Simultaneous Analysis of Anions and Cations by Tandem Chromatography with Conductivity Detection
Application Note Dec 08, 2010
Cecil Instruments Ltd
Tandem chromatography is emerging as a
powerful technique to double the output of HPLC equipment by simultaneously
carrying out two different analyses on the same sample. The principle is
straightforward: the sample is split in two at the injection port, and each
aliquot is eluted on a different column and analysed by a different detector.
This Application Note describes the implementation of this principle to the simultaneous analysis of anions and cations in water, by using “two isocratic ion chromatography systems” working in tandem mode.
