1 Introduction
1.1 Instrument description
The 761 Compact IC is a PC-controlled system for ion chroma-
tographic analyses. The two following versions are available:
• 2.761.0010 Compact IC without suppressor module
• 2.761.0020 Compact IC with suppressor module
The extremely compact housing of the 761 Compact IC contains every-
thing needed to carry out ion chromatography at the highest quality
level:
• Injection valve – for individual injections or for use with a sample
changer such as the Metrohm 766 IC Sample Processor
• 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)
• Pulsation dampener – even with low-level pressure variations the
pulsation dampener reliably protects the column against damage
• 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
• Columns – whether anion columns with or without suppression,
separation columns for cations or organic acids – the 761 Compact
IC can accommodate them all
• Suppressor – the Metrohm Suppressor Module (MSM) is already
integrated in the 2.761.0020 Compact IC – pressure-resistant, with
fully automatic regeneration, highest performance and optimal re-
producibility
• 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 built into the 2.761.0020 Compact IC
• Detector – conductivity detector with outstanding temperature
stability. The detector temperature varies by less than 0.01°C and
can be optimally adapted to the ambient conditions.
All components which come into contact with eluent and sample are
metal-free.
