Introduction

GFS Chemicals Inc - Reliable Chemical Manufacturing for 80 Years!

Since we started manufacturing specialty chemicals in 1928 as The

G. Frederick Smith Chemical Company, customers have learned to

rely on GFS for many good reasons:

Our original focus on

ligands and reagents

needed in analytical chem-

istry protocols gave us a

broad understanding of the

quality control issues that

impact your lab and busi-

ness decisions

Our seminal development

of chemistry of perchloric

acid and perchlorate salts spawned a tradition of engineering

excellence and emphasis on safety that applies to all of GFS

Chemicals manufacturing.

Our ability to actually manufacture reagents across the entire

chemical spectrum.

GFS Chemicals added the Amco Clear® and In-Spec® lines to its prod-

uct catalog in 2003 with the purchase of the APS Analytical Stan-

dards. Since this time GFS Chemicals has used its 80 years experi-

ence in manufacturing analytical

lab reagents to further expand

and improve on the products that

we offer in the Amco Clear® and

In-Spec® product lines. The

Amco Clear® product line now

includes standards for most of

today’s common instruments.

R&D work is always on going to

bring out new products.

Amco Clear® Basics

Amco Clear® has several advantages over formazin-based standards.

A typical mean particle diameter of 0.2 micron ensures consistent

light scattering characteristics, and provides the advantage of perma-

nent suspension. The GFS turbidity standards are significantly more

stable and, unlike formazin-based standards, can be used for calibra-

tion under one nephelometric unit (NTU). This is important because

the EPA requires turbidity values not to exceed 0.3 NTU for surface

source drinking water. GFS maintains the strictest standards of ISO-

9001:2000 conformance.

Advantages

Accurate to 1% lot to lot

NIST Traceable

Stable - a consistent suspension

Easy-to-use - No Mixing and no dilution required

Non-Toxic - No concerns over handling, liability, storage and dis-posal

Available in a wide range of values

Amco Clear Guarantee

The primary standards are guaranteed to be within 1% of the

stated value on the Certificate of Analysis for 1 year from the date

of shipment.

The secondary standards are guaranteed to be within 10% of the

stated value on the Certificate of Analysis for 1 year from the date

of shipment.

Precautions for handling and using the Amco Clear® Standards

Do not allow the standards to freeze or be expose to ex-

treme heat.

The standards are ready to use—do not require shaking.

Replace caps promptly on primary standards.

Use a cuvette stand or other glass holder to keep sealed

standards

Individual Turbidity Standards

GFS Chemicals Inc offers the Amco Clear® primary turbidity standards in

125mL, 250mL, 500mL, 1L and 1 gallon bottles (some standards may not be

available in all sizes). The standards are made instrument specific so instru-

ment make and model must be known in order to verify that the proper stan-

dards are being provided.

Secondary sealed standards may also be offered for use as a daily instrument

calibration verification.

A list is provided on the following pages of the most popular instruments of

which we provide standards for. This is not a complete list of all turbidime-

ters on the market. If you do not see your instrument listed please contact

GFS Chemicals Inc and we will work with you to provide you the correct stan-

dards.

Item #8000—0.0NTU can work for all instruments and can be used when a

0.02NTU standard is required.

Emerson Rosemount

Rosemount Clarity II™

The Clarity II™ turbidimeter is in-

tended for the determination of tur-

bidity in water. Low stray light, high

stability, efficient bubble rejection,

and a display resolution of 0.001

NTU make Clarity II™ ideal for moni-

toring the turbidity of filtered drink-

ing water. Because it measures tur-

bidity as high as 200 NTU, Clarity II™

is also suitable for most raw waters.

The Clarity II™ turbidimeter can be

used in applications other than

drinking water treatment. Examples

are monitoring wastewater dis-

charges, condensate returns, and

clarifiers.

In-Spec® Spectrophotometer Standards

In-Spec® photometric standards are well suited for daily determination of the

photometric accuracy of a spectrophotometer. Other, alternative standards

consist of filters and various dilutions of potassium dichromate and potas-

sium hydrogen phthalate (KHP). In-Spec® photometric standards require no

dilution, preparation or special storage conditions, eliminating user variance.

In-Spec® photometric standards are guaranteed to provide a quick and easy

method of validating a spectrophotometer or colorimeter.

Advantages

Accurate

NIST Traceable

Stable - a consistent suspension

Easy-to-use - No Mixing and no dilu-

tion required

Non-Toxic - No concerns over han-

dling, liability, storage and disposal

Flexible - Use at multiple wave-

lengths specific to your current

testing

Uses

Validate absorbance between instrument calibrations

Validate instrument linearity at a single wavelength

Disinfectant Byproducts Testing via Specific UV Absorption (SUVA)

In-Spec® photometric standards are a NIST traceable liquid standard for use

in UV/Vis spectrophotometers and colorimeters. In-Spec® photometric stan-

dards can be used to determine linearity & accuracy in the UV/Vis range of

190-1100nm. The In-Spec® photometric standards are composed of sub-

micron polymer spheres that will not settle out and provide stable readings

over a one-year period.

The In-Spec® product line also consists of wavelength and stray light stan-

dards that you can use to check the complete health of your spectrophotome-

ter.
