1.1 Instrument description

792 Basic IC

1 Introduction

1.1 Instrument description

The 2.792.0020 Basic IC with suppressor module is a PC-controlled

system for ion chromatographic analyses. The extremely compact

housing of the 792 Basic IC contains everything needed to carry out ion

chromatography at a high quality level:

x Injection valve – for individual injections

x High-pressure pump – extremely low-pulsation double piston

pump with a flow range from 0.2 }2.5 mL/min and a maximum

pressure of 25 MPa (250 bar)

x Column chamber – the perfect insulation of the housing provides

not only thermally stable conditions for the separation column but

also shields the system against electromagnetic interference

x Columns – whether anion columns with or without suppression,

separation columns for cations or organic acids – the 792 Basic IC

can accommodate them all

x Suppressor – integrated Metrohm Suppressor Module (MSM),

pressure-resistant, with fully automatic regeneration, highest per-

formance and optimal reproducibility

x Peristaltic pump – integrated two-channel peristaltic pump with a

flow rate of 0.5 }0.6 mL/min for regeneration and rinsing of the

suppressor module

x Detector – conductivity detector with outstanding temperature

stability. The detector temperature of 40 °C varies by less than

0.01°C.

All components, which come into contact with eluent and sample are

metal-free.

The operation of the 792 Basic IC takes place via a PC connected to

the RS232 interface with the help of the control and evaluation program

«792 Basic IC». This PC program can be used to open prepared sys-

tems for recording and evaluating chromatograms and modify them if

need be. Time programs can also be created in which a large number

of instrument functions can be triggered for each program step.
