Ion chromatography

The Metrohm 861 Advanced Compact IC is used for ion chromatography and water analysis. It has a compact design, high sensitivity, low detection limits, comprehensive automation possibilities - all combined with easy handling.

The unit ensures no injection peak, no carbonate peak and a stable baseline. It combines two effective suppression techniques into a single instrument, namely the second generation of the Metrohm Suppressor Module (MSM II) for chemical suppression that coincides with a new development - the Metrohm CO2 Suppressor (MCS).

The elimination of the carbonate peak removes interferences during the quantification of analyte anions. The absence of an injection peak improves the determination of rapidly eluting anions such as fluoride and also allows larger sample volumes to be injected.

From 5 ppb bromate up to 500 ppm phosphate, no matter with or without suppression, the unit determines everything that can be recorded using conductivity: standard anions in wastewater, drinking or surface water; perchlorate in soil eluates; sulfite, sulfate and thiosulfate in the paper industry; chloride, nitrite, nitrate and sulfate in the cooling water of conventional and nuclear power stations; phosphate and citrate in cola drinks; and cyanate, azide and even chlorate in explosives.

Numerous anion applications for the unit are available in more than 200 application notes, accessible online at www.metrohm.com

The IC can be completely controlled from a PC. The IC Net software carries out both instrument control and data evaluation. With IC Cap the operation of the unit becomes workforce-friendly: a single mouse-click is all that is needed to start a measurement. Both IC Net and IC Cap are included in the standard equipment of the 861 Advanced Compact IC.
