Cyanide and Sulfide Detection Using a New Column for Optimized Separation
22 Jan 2015Trace determination of cyanide and sulfide require an alkaline eluent and amperometric detection. This application note describes a new column/eluent combination for optimized separation. The combination consists of the Metrosep A Supp 10 - 100/4.0 column and a sodium hydroxide eluent containing a trace of EDTA for transition metal complexation. This yields a better peak shape and detection level limits below 0.1 μg/L.
