Users will encounter a new type of chromatography, it is claimed: no more injection peak, no more carbonate peak, and a baseline whose stability is better than anything seen up to now
Metrohm says the 861 advanced compact IC launched at Pittcon 2005, represents a plausible extension of its range of compact IC instruments.
Extremely compact design, high sensitivity, low detection limits, comprehensive automation possibilities - all combined with very easy handling - form the basis for the outstanding performance and success of these IC systems, says the company.
With the 861 advanced compact IC, Metrohm says users will encounter a new type of chromatography: no more injection peak, no more carbonate peak, and a baseline whose stability is better than anything seen up to now.
The 861 combines the two most effective suppression techniques into a single instrument, namely the second generation of the Metrohm suppressor module MSM II for chemical suppression, and a completely new development - the Metrohm CO2 Suppressor
This combination guarantees an accurate and reproducible analysis while representing an entirely new type of ion chromatography, says the company.
The elimination of the carbonate peak removes bothersome 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 considerably larger sample volumes to be injected.
From 5ppb bromate up to 500ppm phosphate, with or without suppression, the 861 is said to determine everything that can be recorded using conductivity: standard anions in wastewater, drinking or surface water, perchlorate in soil eluates, sulphite, sulphate and thiosulphate in the paper industry, chloride, nitrite, nitrate and sulphate in the cooling water of conventional and nuclear power stations, phosphate and citrate in cola drinks, cyanate, azide and even chlorate in explosives.
Numerous anion applications for the 861 advanced compact IC are available in more than 200 application notes, accessible online and free of charge.
The 861 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 861 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.
