What are the optimal uses of the FS 3100 and ion chromatography (IC) in an inorganics laboratory?
Continuous flow analysis (CFA) and ion chromatography are complementary analytical techniques, both of which are commonly used in inorganics lab for automated ion analysis. CFA is optimally used for large sample loads due to its high sample throughput capability. CFA is also used for parameters that cannot be determined by IC including TKN, TP, cyanides, and total recoverable phenolics. IC is best used when a lab needs to determine several anions in the same sample. From a single injection, up to 10 analytes can be determined in drinking water. However, nitrate in drinking (well) water is often in higher demand than the other ions, so a two-channel CFA system running nitrate/nitrite and nitrite simultaneously with automated nitrate calculation are preferable for this application.
