AN71410: Ion Chromatography: A Versatile Technique for the Analysis of Beer (Part E: Inorganic Cation Analysis)

Instrument Type: IC

This application note describes the use of ion-exchange or ion-exclusion chromatography for the determination of five classes of compounds of interest to the brewing industry, including: carbohydrates, alcohols, organic acids, inorganic anions, and inorganic cations. One of two forms of electrochemical detection is used, pulsed amperometry or conductivity detection.This part of the application note describes the inorganic cation analysis which uses conductivity detection. This was formerly Dionex AN46.

AN71410: Ion Chromatography: A Versatile Technique for the Analysis of Beer (Part A: Carbohydrate Analysis)

Instrument Type: IC

This document describes the use of ion-exchange or ion-exclusion chromatography for the determination of five classes of compounds in beer, including carbohydrates, alcohols, organic acids, inorganic anions, and inorganic cations. Although many of these constituents can be determined individually using unrelated analytical techniques, reduced analysis time and equipment costs can be realized by using one instrument with multi-species capability. This part of the work deals with the carbohydrate determination which uses pulsed amperometry determination. This was formerly Dionex AN46.
