Introduction to Sampling The AirCheck Kit™, Models K8573, K8573NB, and K8573NX are designed to follow the ISO 8573 sampling protocols with a few modifications made to the sampling and analytical techniques that provide equivalent results at a fraction of the cost. For details, see AirCheck Notes, 3-3.

The K8573NB, our most popular model allows collection of air samples for solid particles, water vapor, oil aerosol and oil vapor, Model K8573 in addition also allows for capturing gas contaminants, and Model K8573NX in addition also includes Nitrogen Oxides (NOX) and Sulfur Dioxide (SO2) by detector tube. Most samples can be performed simultaneously. If a par-ticular analyte is not required; text in blue provides information on how to correctly eliminate the test.

It is important to note that the sampling equipment design should not be altered in any way that will disrupt the straight flow of gas stream from the sampling outlet to the filter cassette. If a device is installed upstream of the filter cassette; the restrictive orifice should be at least 100 times the size of the largest particle expected.

NOTE: Prior to sampling, it is important to identify the TYPE OF DRYER INSTALLED and the PRESSuRE AT THE SAM-PLINg OuTLET. This information is necessary to select the appropriate water vapor detector tube, flowrate and sampling time, see Table 3: Anticipated Water Level. Accurate sampling point pressure is required as it is used to calculate dew point.

Other gases that can be analyzed include: Routine: Oxygen (O2), Nitrogen (N2), Argon (Ar), Carbon Monoxide (CO), Carbon Dioxide (CO2), Methane (CH4), Total Volatile Hydrocarbons (sample captured in Source Bottle, Model K8573) ISO 8573-6: Carbon Monoxide (CO), Carbon Dioxide (CO2), Sulphur Dioxide (SO2), Hydrocarbons (C1 to C5), Nitrogen Oxides (NOx) (sample captured in Source Bottle and detector tubes, Model K8573NX) Other: Total Halogenated Hydrocarbons, pure gases, or contact us with your specific requirements.

The AirCheck Kit, can be used for a variety of specifications other than ISO 8573. Contact Trace Analytics, LLC to discuss your specific requirements. Sampling media is customized per your air quality testing needs.

Trace Analytics now offers rental equipment for microbial and liquid oil sampling. Contact us for information.

SAMPLINg FOR PARTICLES, WATER VAPOR, OIL AEROSOL, OIL VAPOR, ROuTINE gASES, NITROgEN OXIDES, AND SuLFuR DIOXIDESTEP 1 – Preparation INSPECT and CLEAN Bottle Holder to avoid sampling problems or invalid tests. Disassemble two-part Bottle Holder. Remove o-ring and run Needle Cleaner through both needles from the bottom of the Bottle Holder. Check needles for damage. Replace needles that are crooked, overly bent, or jagged by sliding Needle Tool over needle into slots at base of the needle. Make sure needle is tightly seated. Replace damaged o-rings. Reassemble Bottle Holder. Inspect and clean threaded parts.

INSPECT and CLEAN all other parts to avoid sampling problems or in-valid tests. When there is reason to believe that the adaptor may have been contaminated by aerosol (oil or particulate), the adaptor should be cleaned.

1. Place the adaptor in provided reclosable clear bag or other suitable container.2. Add apx. 20 drops of the provided Luminox™ Low-Foaming Neutral Cleaner*.3. Add warm tap water until the bag is approximately 2/3 full.4. Seal the bag, hold adaptor through bag walls and gently agitate until all of the cleaner is dissolved. Do not shake bag without holding adaptor. Adaptor’s sharp corners can puncture bag.5. Agitate for one additional minute.6. Empty bag into an appropriate sink.7. Rinse the adaptor in the bag under warm running water until all traces of the cleaner have disappeared.8. Using the bag as a glove, turn the bag inside out while holding onto the adaptor through the bag wall.9. Rinse the adaptor with isopropanol until all traces of water are re-moved. (Isopropanol not provided.)10. Shake the liquid from the adaptor; it is now ready for use.NOTE: Luminox cleaner and isopropanol do not interfere with ISO 8573-1 contaminants determination.

*MSDS available in Helpful Technical Info at www.AirCheckLab.com.

Adaptors can also be cleaned in ultrasonic bath or other method. Do not clean with solvents such as acetone, hexane, etc. that can interfere with GCMS analysis.

If flowmeters are contaminated or non-functioning, they will need to be replaced. Refer to parts list for part number.

Inspect and remove any glass shards from previous tests in Tube Holder of Tube Flowmeter.

Select sampling media (filter cassette, detector tube, charcoal tube, and field blanks as appropriate) and data sheet to be used based on your spe-cific testing requirements. Enter all required information on data sheet except for flow rates and sampling times.

Clear Needles Prior to Sampling



STEP 2 – Assemble EquipmentSlowly open the sampling outlet valve and allow air/gas to flow for at least two minutes before attaching equipment to sampling outlet. Select NPT adaptor to be used. If outlet pressure is 20-50 psig; use the unrestricted adaptor marked UNR, if outlet pressure is 51-125 psig; use adaptor marked 41.

Inspect Double Tee and tighten connections as necessary. Attach labeled end of the appropriate NPT adaptor to the male threaded end of the Double Tee and securely tighten (if not already attached). Attach appropriate fitting to connect to your sampling point (not included). Attach Bottle Holder to top threaded hole on the Adaptor taking care not to cross-thread fittings. Attach the 1/4” NPT adaptor to the sampling outlet.

Using 9/16” and 1/2” wrenches to connect the Swagelok tube fittings, from the base of the H2O/OV Tube Flowmeter (1-5 LPM) to one side-arm of the Double T. The upper back hole of Tube Flowmeter must remain unplugged to vent air.

Select the small 5/16” Tube Holder for Water test (or larger 3/8” Tube Holder for Oil Vapor test if not performing water test), thread the Tube Holder onto top of H2O/OV Tube Flowmeter (1-5 LPM), and close needle valve (turn clockwise, do not overtighten). CAuTION Take care to avoid stripping plastic threads of Tube Holder, spares included in plastic bag.

Using 9/16” and 1/2” wrenches to connect the Swagelok tube fittings, from the base of the NOX/SO2 Tube Flowmeter (0.04-0.5 LPM) to the other side-arm of one of the Double T. A 5/16” Tube Holder should be attached to top of Flowmeter. The upper back hole of Tube Flowmeter must remain unplugged to vent air. Thread male threaded Filter Cassette side with red label marked “NPT” onto the female threads of the manifold. Thread plastic fitting from tubing to downstream side of Cassette labeled “FLOWMETER”. Slip open end of Tubing onto barbed fitting at base of Filter Flowmeter (20-140 LPM). The upper back hole of Filter Flowmeter (20-140 LPM) must remain unplugged to vent air.

Note: Flowmeter Reading Diagram: Flowmeter must be level for proper reading. Tube flowmeter is read at the middle of the float; Filter flowmeter is read where the float changes from straight sides to angled (see diagram).

STEP 3 – Begin Filter Testif you are not sampling for particles or oil aerosol; attach “tester” filter cassette and skip to step 4

Aerosols and Particles are collected simultaneously on Filter Cassette.

If sampling for BOTH Aerosols and Particles, use Table 1.

If sampling ONLY for Particles, use Table 1.

If sampling ONLY for Aerosols, use Table 2.

Select the flow rate and sample time based on the ISO 8573-1:2010 Purity Class you are attempting to comply with. If Purity Class is unknown and you are performing a Baseline sample; use either Class 1 or the most stringent Class you anticipate needing. Filter cassette should remain in place until you have completed all other tests (all gases, water vapor and oil vapor.)

Ensure that the TUBE Flowmeter needle valve is closed, turn clockwise (do not overtighten). BEGIN TIMING TEST* Open system valve slowly to obtain a reading from the FILTER Flowmeter. See Flowmeter Reading Diagram to properly read the flowrate. Identify flowrate and sampling time from above Tables. The Flowmeter reading should be steady. If flow-rate drops or varies, determine average flowrate and note on data sheet that steady flowrate not achieved. The Adaptor Assembly may become cold and ice up. This is normal. CAuTION Do not obstruct exit air from flowmeters as this will cause inaccurate flow readings.

* It is helpful to jot down the “clock time,” as the filter test will run while gases, water vapor and oil vapor tests are also performed. The total amount of time air flows across the filter must be recorded. It is accept-able for the length of time to be more than recommended in Tables 1 & 2.

If unable to achieve recommended flowrates, use the formula below to determine the number of minutes to sample based on the minimum air volume listed in Table 1 or 2.

FLOWRATE, LPM= Sample Time, min.

DATA SHEET NOTE: Record filter number (if not already done), and flowrate on data sheet. Record Ambient Temperature which is the temperature in room. Record Ambient Pressure which is local barometric pressure (can be found by searching internet). Proceed to next step.

FIELD BLANK: For each batch of samples that will be submitted at one time, prepare one field blank; select a “blank” filter cassette, enter the number on 1 data sheet, and return the unused field blank cassette with day’s batch of sample(s). Samples can be submitted without a Field Blank if blanks are unavailable. Batch is to be determined by end user. Common practice is 1 BLANK per day of sampling. A blank is for laboratory use only - DO NOT flow air through the blank filter.

STEP 4 – Begin Source Bottle Test if you are not sampling for routine gases; skip to step 5.The Source Bottle should be in place during the Water Vapor Test de-scribed in Step 5 to avoid a change in flow rates. To avoid puncturing the blue cap, hold the Source Bottle against the inside wall of the Bottle holder closest to the outer needle. Then slide Source Bottle inside bottle holder. Gently push onto needles. DO NOT • twist bottle when inserting or removing • puncture Source Bottle more than once • reuse Source Bottle or Detector Tubes

STEP 5 – Begin Water Vapor Testif you are not sampling for water vapor; close needle valve, skip to step 6.There are two types of detector tubes: 5/a-P for dew points (-40°F through -4°F) and high dew points (-20°F through +50°F). Select the de-tector tube for your anticipated dew point. If unknown, use the 5/a-P.

Make certain that the 5/18” Tube Fitting is threaded onto top of Tube Flowmeter. Turn Tube Flowmeter needle valve counterclockwise to ob-tain a flowrate of 4 LPM and allow to flow for 2 minutes to expel any ab-sorbed water. See Flowmeter Reading Diagram (p. 1-5) to properly read the flowrate.

Remove both tips of Detector Tube by placing each tip in small hole of Tip Breaker and applying sideways pressure until tip breaks. CAuTION when opening, inserting or removing tube, glass may splinter. Danger of injury due to sharp edges. Position tube and tip breaker over appropriate receptacle to capture any glass shards. Tip Breaker has ends capped to capture broken glass. Remove caps on Tip Breaker to dispose of glass.

Immediately insert detector tube firmly into 5/16” Tube Holder with ar-row on detector tube pointing away from flowmeter. Hand tighten nut on Tube Holder. Re-adjust flowrate if necessary to 4 LPM and BEgIN TIMINg TEST per Water Level Table 3. Apply protective netting over de-tector tube and Tube Holder.

At the end of Sampling Time, close needle valve clockwise, loosen nut, remove tube, and immediately record the following information on the data sheet: number associated with color change from the tube, flowrate, sampling time, sampling point pressure, type tube (5/a-P or 20/a-P) used, and if 20/a-P tube used; circle scale used. At any time during the test if the color changes on the detector tube to a grayish / reddish brown AND reaches the last line/reading on the tube, immediately close Tube Flowmeter valve and remove the tube and note elapsed time on data sheet. Immediately, and in no more than 1 minute, record the NuMBER

FROM THE TuBE associated with the color change on the Detector Tube. Cap both ends of tube and re-apply protective netting. Place tube in re-turn mailer.

DATA SHEET NOTE: Sampling Point Pressure must be deter-mined by pressure gauge. This data should be as accurate as possible as it is used to calculate the dew point at pressure for your AirCheck Report. If pressure gauge unavailable, use line pressure closest to sampling point and make a note in the Comments section on Data Sheet.

REMOVE SOuRCE BOTTLE from Bottle Holder and record Source Bottle Number on data sheet.

STEP 6 – Begin NOX/SO2 Testsif you are not sampling for nox/so2; close needle valve, skip to step 7.

Adjust NOX/SO2 flowmeter to about 0.25 LPM.

6a Select one NOX detector tube for each test. Remove the RED caps from the NOX tube. Further identify the tube by checking the wording on the sides of tubes.

Remove both tips of Detector Tube by placing each tip in small hole of Tip Breaker and applying sideways pressure until tip breaks, as shown previously. CAuTION when opening, inserting or removing tube, glass may splinter. Danger of injury due to sharp edges. Position tube and tip breaker over appropriate receptacle to capture any glass shards. Tip Breaker has ends capped to capture broken glass. Remove caps on Tip Breaker to dispose of glass.

Insert the tube in the NOX/SO2 flowmeter (0.1-0.5 LPM) with the arrow pointing away from the flowmeter, and BEgIN TIMINg the test for 5.0 minutes. Apply protective netting over detector tube and Tube Holder. Immediately adjust flows to 0.2 LPM and readjust as necessary to main-tain. After 5.0 minutes, remove the tube and cap securely.

You can proceed to Step 7 to begin the oil vapor test concurrently with NOX/SO2 sampling.

Immediately after sampling, read the tube in a well lighted area using a light background such as the reverse side of the Data Sheet. Record the reading of the final edge of discoloration; comparing to an unused tube will aid in taking this reading. NOTE: If no discoloration, enter a 0 on the Data Sheet.

6b NOX produces a color change from pale green to blue gray.

If the color change on the 5/a-P tube reads greater than 200 between 5.0 and 12.5 minutes, stop test; and redo test using the 20/a-P tube.

If color change on the 5/a-P tube is between 100-150 for less than 5 minute; use Class 4 sampling time with the 20/a-P tube.

If color change on the 5/a-P tube is greater than 150 for less than 5 minutes; use Class 5 sampling time with the 20/a-P tube.

use 0.1-0.5 Flowmeter

for NOX & SO2



Record the ACTUAL flow rate, tube reading, and total minutes sampled in Section 7 of data sheet and NOX.

6c Select one SO2 detector tube for each test. Remove the GRAY caps from the SO2 tube. Further identify the tube by checking the wording on the side of the tube.

Repeat instructions from 6a.

6d NOTE: The SO2 tube has two scales; use the 1-25 scale. NOTE: If no discoloration, enter a 0 on the Data Sheet.

SO2 produces a color change from gray blue to white.

Record the ACTUAL flow rates, tube readings, and total minutes sam-pled for EACH Detector Tube in Section 7 of data sheet for NOX/SO2, respectively.

STEP 7 – Begin Oil Vapor TestThis portion of the test will take a minimum of 10 minutes or more de-pending on the ISO Class you select. if you are not sampling for oil vapor; close needle valve, skip to step 8.

Make certain that the 3/8” Tube Fitting is threaded onto top of Tube Flowmeter. Turn Tube Flowmeter needle valve counterclockwise to obtain a flowrate of 4 LPM. See Flowmeter Reading Diagram (p. 1-5) to properly read the flowrate.

Remove tips of Oil Vapor Tube by placing each tip in LARGE hole of Tip Breaker and applying sideways pressure until tip breaks. CAuTION when opening, inserting or removing tube, glass may splinter. Danger of injury due to sharp edges. Position tube and tip breaker over ap-propriate receptacle to capture any glass shards. Tip Breaker has ends capped to capture broken glass. Remove caps on Tip Breaker to dispose of glass.

Insert charcoal tube with arrow on charcoal tube pointing away from flowmeter into 3/8” Tube Holder atop Tube Flowmeter. Push gently until it reaches the bottom of Tube Holder. Hand tighten nut on Tube Holder. Re-adjust flowrate if necessary to 4 LPM and BEgIN TIMINg TEST as indicated in Oil Vapor Flowrate Table. Apply protective netting over detector tube and Tube Holder. If Purity Class is unknown and you are performing a Baseline sample; use either Class 1 or the most strin-gent Class you anticipate needing.

At end of sampling time, remove charcoal tube, close needle valve clockwise. Record tube number (if not already done), flowrate and sam-pling time on data sheet. Cap both ends of charcoal tube and re-apply protective netting. Place charcoal tube in return mailer.

Record TOTAL time sampled for the Filter Cassette.

FIELD BLANK: For each batch of samples that will be sub-mitted at one time, prepare 1 field blank; select a “blank” charcoal tube, enter the number on 1 data sheet, break tips and immediately cap, and return the unused field blank charcoal tube with day’s batch of sample(s).
