Sulphur and Halide Determination by Combustion Ion Chromatography

The fully automated combustion ion chromatography (CIC) system presented here combines a highly efficient combustion system with the separation power of ion chromatography (IC). CIC allows for the simultaneous, speciated trace analysis of halide (F, Cl, Br and I) and sulphur compounds (as sulphate) from sub-ppm to percent levels in any nonaqueous sample matrix.

Trace-Level Aliphatic Amines in Cationic Drugs

The analytical challenge treated in the present work consists in determining sub-ppb concentrations of low-molecular-weight amines in the presence of strongly retained cationic drugs by using ion chromatography (IC) with upstream in-line coupled-column matrix elimination (CCME).
