1 Introduction

1.1 Instrument description

The 930 Compact IC Flex is a robust ion chromatograph. It is distinguished

by:

￭Its intelligence: All of the functions are monitored, optimized and docu-

mented in an FDA-compatible manner. Intelligent components, such as

iColumns, save important data onto a chip.

￭Its compact design: It has a small footprint.

￭Its transparency: All components are easily accessible and located for

simple visibility and can be monitored during operation through a large

window.

￭Its safety: The wet end and the electronics are physically separated.

This prevents fluids from coming into contact with the electronics to a

large extent. A leak sensor is integrated into the wet end.

￭Its environmental compatibility.

￭Its low noise emission.

￭The intelligent MagIC Net software.

The 930 Compact IC Flex is operated using the MagIC Net software. A

USB cable is used to connect the device to a computer with MagIC Net

installed. The intelligent software detects the device automatically and

checks its functionality. The software controls and monitors the device,

evaluates the measured data and manages it in a database.

The 930 Compact IC Flex Oven/SeS/PP consists of the following modules:

Housing

The sturdy housing contains the instrument's electronic components,

including their interfaces and one connector for a separation column. In

addition, the housing provides space for a conductivity detector or an

amperometric detector. Capillaries and cables can be fed into and out of

the instrument through several openings.

Leak sensor

The leak sensor detects leaking liquid that collects in the instrument's base

tray. Liquid that leaks in the instrument is routed to the base tray using

drainage tubing and detected there.

Column oven

The column oven regulates the temperature for the separation column

and the eluent, thereby providing stable measuring conditions. There is a

column holder with chip reader in the column oven.

High-pressure pump

The intelligent and low-pulsation high-pressure pump pumps the eluent

through the IC system. It is equipped with a chip where its technical speci-

fications and "life history" (operating hours, service data, etc.) are stored.

Inline filter

Inline filters protect the separation column reliably from potential contam-

ination from the eluent. The filter pads with 2 µm pore size can be

replaced quickly and easily. They remove particles from the solutions, such

as bacteria and algae.

Pulsation absorber

The pulsation absorber protects the separation column from damage

caused by pressure fluctuations, e.g. when the injection valve is switched,

and reduces interfering pulsations during highly sensitive measurements.

Injection valve

The injection valve connects the eluent path to the sample path. By a

quick and precise switching of the valve, a quantity of sample solution

defined by the size of the sample loop is injected and flushed to the sepa-

ration column with the eluent.

Metrohm Suppressor Module (MSM)

The chemical suppressor MSM consists of the suppressor drive, a rotor

and, where applicable, an adapter. The suppressor drive gives you the flex-

ibility to use different rotors according to the principle "one drive – many

rotors". Suppression rotors with different capacities and construction or a

rotor for sample preparation (SPM Rotor) are readily interchangeable with

appropriate adapters as needed. The rotors are not included in the instru-

ment's scope of delivery. The rotor required for the application and any

adapter that is required must be ordered separately.

Peristaltic pump

The peristaltic pump is used for pumping sample and auxiliary solutions. It

can rotate in both directions.

Metrohm CO2 Suppressor (MCS)

The Metrohm CO2 Suppressor (MCS) removes the CO2 from the eluent

stream. This lowers the background conductivity, improves detection sen-

sitivity and minimizes the injection peak and system peak.

Detector

Metrohm offers a series of different detectors for various analysis tasks. A

suitable detector type must be ordered as a separate device.
