Simultaneous determination of sodium dialkyldithiocarbamates by ion exchange chromatography.

Rapid determination of urinary total porphyrins by ion exchange chromatography.

Total urinary porphyrins were eluted from a commercially available anion exchange Chromatographie column with hydrochloric acid and determined spectrophotometrically. For 1 ml samples the optimum concentration range for measurement was found to lie between 0.1 and 1.5 mg of total porphyrin/1 urine. Assay of a single sample takes 12 min. The specificity (measurement at three wave lengths), sensi...

Determination of sodium azide in beverages by ion chromatography.

A convenient method for determination of sodium azide in beverages using ion chromatography is described. This method combines the specificity for azide with a simple sample preparation using a bubble and trap apparatus that removes any interferences. Sodium azide in a sample was acidified, and the azide was converted to the volatile hydrazoic acid, which was trapped in 2.5 mM sodium hydroxide ...

Recent progress and applications of ion-exclusion/ion-exchange chromatography for simultaneous determination of inorganic anions and cations.

One of the ultimate goals of ion chromatography is to determine both anions and cations found in samples with a single chromatographic run. In the present article, recent progress in ion-exclusion/ion-exchange chromatography for the simultaneous determinations of inorganic anions and cations are reviewed. Firstly, the principle and the control for the simultaneous separation and detection of ...
