Highlights

Flow path features

The flow path of the 850 Professional IC is metal-free

and biocompatible. Most applications permit Green Che-

mis try without toxic solvents, corrosive eluents or even

cartridges that have to be disposed of as hazardous

waste. Nevertheless the system is 100% solvent-resistant

and withstands even rough surroundings. Eluents are

automatically degassed inline and the MagIC NetTM soft-

ware ensures that they are always fresh.

Automated eluent preparation

The time-consuming manual preparation of the eluents

can be automated. One of the options offered by

Metrohm to realize this is the 845 Eluent Synthesizer,

which prepares eluents from up to four freely selectable

concentrates and one main component. Compared to

the traditional manual eluent preparation, the fully auto-

mated system guarantees precise mixtures and excellent

batch-to-batch reproducibility by simple mouse-click in

the «Mix Control» program.

04 Another option is preparing the eluent directly inline. This

is done by connecting the 849 Level Control and the 800

Dosino to the 850 Professional IC system. Controlled by

MagIC NetTM, the 849 Level Control monitors the eluent

level while the Dosino carries out all the required dosing

and liquid-handling operations. In this case, eluent pre-

paration runs parallel to the determination. The system

allows continuous ion chromatographic analyses over a

month without any manual eluent preparation being

required.

The error-prone and time-consuming eluent pre-

paration can be automated at small additional

cost.

05

Gradients – if necessary

High-pressure or low-pressure gradients are used only

where they are really needed. Gradient form and mixing

are freely selectable: step, linear, convex and concave

gradient functions are available and can be combined.

The 850 Professional IC system is available as a high-

pressure or low-pressure gradient version. Moreover, all

850 Professional IC systems can be operated with the

Dosino Gradient as well.

The high-pressure gradient system can be expanded to

a quaternary gradient system with the 872 Extension

Mo dule.

The low-pressure gradient version is the economic alter-

native to the powerful high-pressure gradient system.

The low-pressure gradient module can also be used for

method development or as eluent selector for the auto-

matic switchover from one application to another.

The gradient systems are available with chemical suppres-

sion, with sequential suppression or without suppres sion,

depending on the requirements. They can be combined

with a broad range of detectors and are suitable for hy -

dro xide as well as carbonate gradients. When working

with sequential suppression and conductivity detection,

the flexibility of the carbonate/hydrogencarbonate elu-

ents can be combined with the low background conduc-

tivity of an hydroxide eluent by the CO2 suppression

app lied after the chemical suppressor.

For gradient applications we recommend the high-ca pa-

city Metrohm Suppressor Module «MSM-HC» to be used

for chemical suppression.

06 Self-monitoring for zero fault tolerance

The intelligent system components monitor and optimize

all functions, which are, if required, documented in an

FDA-com p liant form. The configuration of the system is

as simple as can be imagined, as the components log

themselves in automatically and provide the MagIC NetTM

software with all the relevant information. The way from

the sample to a precise result has become quicker as

even complex sample preparation steps are now carried

out inline and automatically. If necessary, the system will

also automatically optimize sample preconcentration or

sample dilution. The optimal operation of the 850 Pro-

fessional IC and the results are monitored. If a parameter

leaves the predefined range then the user is infor med by

E-Mail or SMS.

Intelligent system

850 Professional IC is a system composed of discrete,

intelligent modules that are optimally matched to one

another. The way from the sample to a precise result has

now become easier, as the system thinks for itself and

makes logical decisions. This prevents operating errors

and improves reliability of results.

The 850 Professional IC is a complex and very efficient

system that can still be operated simply and intuitively

with the MagIC NetTM software. This applies for both

power users with complex applications and complicated

calculations and users who value «one-button opera-

tion». Any user level is possible. Innovation, flexibility and

extremely simple operation result from the intelligence of

the 850 Professional IC, the 872 Extension Module, the

858 Professional Sample Processor and the MagIC NetTM

software.

Intelligent components for an intelligent system

07

The 850 Professional IC system is highly flexible. The prin-

ciple of discrete modules combined into a system means

that users are perfectly prepared to meet ever new and

more demanding challenges. Read more about new

options with the 872 Extension Modules from page 22

on. Moreover, all 850 Professional IC systems can be

com bined with Metrohm’s unique Inline Sample Pre pa-

ra tion techniques (page 13). They provide for a fully

auto mated and reliable analysis of liquid, solid and even

gaseous samples in a single run.

Flexibility in the use of the detection method

Conductivity detection is the most frequently used detec-

tion method in ion chromatography. Metrohm’s iDetec-

tor is a state-of-the-art, powerful and intelligent detec-

tor. If your sam ples require a different detection method,

you can use UV/VIS detection, electrochemical methods

or mass spectroscopic methods as well.

Flexibility in the choice of the separation coulumn

We offer you a wide range of different columns. Depen d-

ing on your application you can choose columns with

various base materials, selectivity, capacity and dimen-

sions. Be sides columns with an inner diameter of

4 mm we can even offer you 2 mm columns to reduce

eluent consump tion. For these «microbore columns» we

have deve loped our new chemical suppressor «MSM-LC».

850 Professional IC system at a glance

091 Housing

All components of the 850 Professional IC are easily

accessible and well laid out. Extensions can be made

at any time – the system grows to meet your require-

ments. The flow path for the application is metal-free

and already preinstalled. The transparent door allows

visual monitoring during the analysis.

2 Eluent transfer

The iPump is a central element of the 850 Professional

IC. Its extremely low pulsation translates into low noise

and consequently in to highest sensitivity of the ana-

lytical system. The iPump optimizes its flow rate on its

own; its memory chip stores all the important infor-

mation.

3 iColumns

The iColumn, the analytical separating column, is the

heart of any application. Thanks to the iColumn tech-

nology, the optimal chromatographic conditions are

stored on a chip, which prevents damage due to ope-

ra tional errors. Moreover, if the iColumn is used on a

different Professional IC system no information is lost

which means that the analytical process is traceable

without any gaps.

4 Column thermostat – hot or cold?

Any temperature between 0 °C and 80 °C is possible.

The analytical columns and the applications determine

how hot or cold the column thermostat has to be. It

can contain up to two iColumns, a further column can

be operated externally at room temperature.

5 Suppression

Sequential or chemical suppression – both allow highly

sensitive analyses due to very low background conduc-

tivity. The 850 Professional IC is now available not only

with the «MSM II» chemical suppressor but also with

the high-capacity «MSM-HC» suppressor or with the

low-capacity «MSM-LC» suppressor. With 0.2 nS/cm

these suppressors have the lowest noise of all suppres-

sors. Metrohm suppressors are extremely robust and

resistant to both solvents and pressure; the reason why

they come with a 10-year warranty.

6 Detection

After their separation on the iColumn the ions pass,

e.g., the intelligent conductivity detector of the 850

Professional IC. The detector transfers the digitized

signal directly to the MagIC NetTM software. Outstanding

temperature stability, a Faraday cage and the latest

generation of DSP – Digital Signal Processing – guaran-

tee highest pre cision. The wide measuring range of the

iDetector of 0...15 000 μS/cm ensures accurate and

precise re sults from traces to percentage – in one

determination.

7 Automation

The 858 Professional Sample Processor is more than

just a sample changer. Equipped with pumps, injection

valve and Dosinos it makes an integral contribution to

Inline Sample Preparation and Liquid Handling. More

than 30 different sample racks are recognized auto-

matically, which means that with respect to their form

and volume very individual sample vessels can be used.

The standard version accommodates 148 samples.

8 Software

Clear symbols, well-laid-out presentation, intuitive ope-

ra tion, «one-button IC»: that‘s MagIC NetTM. Com plete

system monitoring, control cards, comfortable da tabase

functions are additional features of MagIC NetTM, the

intelligent software for con troll ing the 850 Professional

IC and evaluating the data. All 850 Pro fessional IC

instruments, all intelligent Compact IC ins truments,

872 Extension Modules, 858 Pro fess io nal Sample

Processors, 800 Dosinos and iCo lumns are automati-

cally recognized, monitored and controlled.

Suppression

Ion chromatographic analysis, especially that of anions,

uses chemical as well as sequential suppression to reduce

background conductivity and increase sensitivity. Chemical

suppression is based on salts of weakly dissociated acids

(e.g., NaHCO3 / Na2CO3), which produce carbonic acid

sub sequent to cation exchange. The chemical suppres-

sion improves the sensitivity by a factor of 2 to 5.

Sequential suppression

Sequential suppression combines chemical suppression

with Metrohm CO2 Suppression (MCS). «MCS» removes

any carbonate and the CO2 that is produced by the sup-

pressor reaction. This allows the determination of anions

with the flexibility of carbonate/bicarbonate elu ents while

benefitting from a low background conductivity corre-

sponding to that of hydroxide eluents. More over, the

in terference by the carbonate peak during the quantita-

tion of analyte ions is completely eliminated.

Additionally, sequential suppression improves detection

limits and produces a remarkably smaller injection peak,

which in turn improves the determination of the fast-

eluting ions such as fluoride.

«MSM II», «MSM-HC» and «MSM-LC»

With the chemical suppressors «MSM II», «MSM-HC» and

«MSM-LC» you can choose exactly the right suppressor

for your application. The «MSM II» is our standard supp-

ressor. The «MSM-HC» was developed for gradient app-

li cations, but can also be used for isocratic applications

with columns with very high capacity. The low capa-

city «MSM-LC» was developed to be used with 2 mm

columns. The very low noise of less than 0.2 nS/cm for

all three suppressors guarantees an extremely high sensi-

tivity of the 850 Professional IC system. The robustness

and resistance against solvents and pressure allows

Metrohm to grant a unique 10-year warranty for these

suppressors.

11

Reproducibility of suppression

The state-of-the-art tri-chamber suppressor technology

provides a fresh suppressor chamber for each measure-

ment. The complete regeneration of the chamber after

each sample ensures highly efficient cation exchange –

today, tomorrow and even after years of continuous

operation.

Automation

Automation in ion chromatography not only ensures

opti mal use of the working hours but also improves the

reproducibility of the results. There is no more reason to

waste time on routine tasks such as manual sample in-

troduction or sample preparation. The sample changer

takes over all these functions. We offer you five different

sample changers: The 858 Pro fessional Sample Processor,

the 863 Compact IC Auto sampler, the 889 IC Sample

Center, the 814 USB Sample Processor and the 815

Robotic USB Sample Processor XL.

858 Professional Sample Processor – the perfect

match for the 850 Professional IC

The 858 Professional Sample Processor is more than a

simple sample changer. Equipped with pumps, injection

valve and Dosinos, it can be an integral part of Inline

Sample Preparation and Liquid Handling. More than 30

different sample racks are automatically recognized,

allowing the use of sample vessels that are different in

shape and volume. The standard version of the 858 Pro-

fessional Sample Pro cessor accommodates 148 samples.

The 858 Professional Sample Processor can access up to

999 sample positions. It is also possible to use an external

position for performing tasks such as dilutions or rinsing

the needle.

The 858 Professional Sample Processor handles sample

volumes ranging from 500 μL to 500 mL. Sample trans fer

is carried out by a peristaltic pump or a Dosino. De pend-

ing on the version of the 858 Professional Sample Pro-

cessor, an additional six-port injection valve is available

for sample preparation.

13Metrohm Inline Sample Preparation (MISP)

Crystal clear, clinically pure, no bacteria and no particles:

this would be an ideal sample for ion chromatography.

Unfortunately, apart from the ions to be determined, the

samples often contain large amounts of interfering sub-

stances that make the analysis difficult if not impossible.

Critical samples such as milk, chocolate, caustic soda so -

lutions, biodiesel or strongly loaded waste waters re quire

sample preparation before they can be analyzed by IC.

However, manual sample preparation is time-consuming

and in many cases results in poor reproducibility, in ac cu-

rate results and high costs.

With Metrohm Inline Sample Preparation «MISP», many

of these steps can be automated, significantly increasing

the quality of the results and drastically reducing costs. In

these systems, sample preparation is integrated between

the sample changer and the IC system.

Combined with the 858 Professional Sample Processor,

the 850 Professional IC offers a variety of fully automated

inline sample preparation steps such as Ultrafiltration,

Dia lysis, Preconcentration, Matrix Elimination, Neu trali-

zation, Inline Calibration, intelligent Partial Loop Injection

Technique and Sample Dilution.

Metrohm’s powerful MagIC NetTM chromatography soft-

ware further expands the application range and provides

the ability to make logical decisions such as applying the

automatically calculated dilution factors.

Metrohm Inline Sample Preparation (MISP): These techniques are the key to complete automation of your analyses. Samples are introduced by means of a Sample Processor. Sub -sequently, they are subjected to one of Metrohm’s Inline Sample Preparation techniques. Finally, they are directly injected into an ion chromatograph. This fully automated sequence is the common principle of all MISP techniques.

tion – in the ppb range (μg/L).

The sample is transferred to the preconcentration col-

umn fully automatically and with high precision by the

intelligent 800 Dosino. The anions or cations are retained.

The matrix can be removed in a rinsing step. The clean

sample is then transferred to the IC system.

The 850 Professional IC – Prep 2 is equipped with an

additional valve for liquid handling. The peristaltic pump

transfers the standard. The intelligent MagIC NetTM soft-

ware controls and monitors the system.

Applications

• Ultratrace analysis for anions and cations in

- Nuclear power plants

possi bilities of Inline Sample Preparation and Liquid Hand-

ling. Additional flexibility results from implementing column

selection systems, cutting techniques or multi di men sional

IC applications.

The 872 Extension Modules enhance the capabilities of

the 850 Professional IC family.

The flexibility of the 850 Professional IC allows to tailor

the system to the application according to your needs.

Determination of anions and cations in parallel for one

application and a quaternary gradient for another appli-

cation are all simple tasks.
