AS 3741-1990

Sets out recommendations for instrumentation and operating techniques for the chemical analysis of anionic or cationic species by ion chromatography. The Standard includes both suppressed and non-suppressed ion chromatographic techniques. Ion-pairing and ion-exclusion techniques are not covered in this Standard.

This Standard sets out recommendations for instrumentation and operating techniques suitable for chemical analysis of both cationic and anionic species by non-suppressed (sometimes referred to as electronic suppression) and suppressed (sometimes referred to as chemical suppression) ion chromatographic techniques. Accepted methods of ion chromatography are based on ion-exchange, ion-pairing or ion-exclusion separation, all of which have similar principles; for simplicity, only procedures based on ion-exchange are referred to in this Standard. This Standard includes a summary of instrument testing procedures to ensure correct calibration and operation of the instrument.
