- High Performance Liquid Chromatography -

CALCE uses the Dionex-600 high performance liquid chromatograph (HPLC) with the AS4A-SC column with eluent 1.8mM Na2CO3/1.7 mM NaHCO3 for the determination of anions at the ppm level in the extraction solution of plastic materials and printed wiring boards (PWBs). CALCE can detect chloride, bromide, fluoride, nitrite, nitrate, phosphate, sulfate, and oxalate anions with this column and eluent solution.
