Detecting halogens and sulphur using combustion ion chromatography

This article presents a method that combines combustion digestion and ion chromatography into a single analysis (combustion ion chromatography [CIC]) making it possible to detect halogens and sulphur in complex matrices. The method is suitable for use in a wide range of application areas.

Tips on troubleshooting HPLC problems

In the latest instalment of The Essentials, the following questions were submitted by CHROMacademy members as part of the “HPLC Troubleshooting Master Class” series, which focused on real life problems in the modern chromatography laboratory.

The ins and outs of ion chromatography

Ion chromatography (IC) is often used for the chromatographic separation of a wide range of compounds. In a laboratory that already uses HPLC or UHPLC, will the implementation of ion chromatography be expensive in terms of instrumentation or resources? The Column found out more.

The benefits of capillary ion chromatography

The first commercial capillary ion chromatography (IC) systems became available in 2010, but uptake of the technique has been slow even though it has many benefits. Here, we review those benefits and present selected application areas where it is proving especially useful.
