1 Introduction

1.1 Instrument description

The 883 Basic IC plus is an intelligent, very compact ion chromatograph

for education and routine analysis. The instrument is distinguished by:

￭the intelligence of its components, which are able to monitor, opti-

mize and document all functions.

￭its compact design.

￭its transparency. All components are easily accessible and located for

simple visibility.

￭its safety. Chemicals and electronics are separated.

￭its environmental compatibility.

￭its low noise emission.

The instrument is operated with the MagIC Net Basic software. It is con-

nected to a PC on which MagIC Net is installed via a USB connection. The

software detects the instrument automatically and checks its functional

readiness. MagIC Net controls and monitors the instrument, evaluates the

measured data and manages it in a database. The operation of MagIC Net

is described in the "Tutorial for MagIC Net" as well as in the online help.

The instrument contains the following components:

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 contami-

nation 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

2￭￭￭￭￭￭￭￭ 883 Basic IC plus

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

ration column with the eluent.

Suppressor

The suppressor consists of the suppressor drive, the MSM Rotor A and an

adapter.

Peristaltic pump

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

can rotate in both directions.

Conductivity detector

The conductivity detector continuously measures the conductivity of the

liquid passing through and outputs these signals in digital form (DSP –

Digital Signal Processing). The conductivity detector exhibits outstanding

thermal stability and thus guarantees reproducible measuring conditions.

Separation column

The intelligent separation column separates different components accord-

ing to their interactions with the column. Metrohm separation columns

are equipped with a chip where their technical specifications and history

(start-up, operating hours, injections etc) are stored.

1.2 Intended use

The 883 Basic IC plus is used for the determination of anions or polar

substances with chemical suppression using ion chromatography. It can

also be used as needed for the determination of anions without chemical

suppression or for cations.

This instrument is suitable for processing chemicals and flammable sam-

ples. Therefore, the use of the 883 Basic IC plus requires the user to have

basic knowledge and experience in handling toxic and caustic substances.

Knowledge regarding the application of fire prevention measures prescri-

bed for laboratories is also mandatory.
