Determination of chlorine-containing compounds in disinfectants using ion-exchange chromatography

Determination of chlorine in organic compounds containing mercury

The standard procedure for the determination of chlorine in organic compounds of mercury consists in decomposition of the material, separation of mercury and determination of chlorine as chloride. Decomposition of the sample could be achieved by wet mineralization [1,2], ignition in a stream of oxygen [3—7] or nitrogen [8], ignition in a flask with oxygen [9], etc. [10, 11]. Chlorine and mercur...

Ion exchange chromatography of prolactin in urea-containing buffers.

Moore and Stein (1) have reviewed the work of Boardman and Partridge and others on problems encountered in attempting the chromatography of nonbasic proteins on Amberlite IRC-50 by elution analysis with the use of buffers of constant composition for the elution. Boardman and Partridge (2) suggested that the difficulty in achieving reversible equilibrium binding was due to hydrogen bonding betwe...

Determination of Cyanogenic Compounds in Edible Plants by Ion Chromatography

Cyanogenic glycosides are HCN-producing phytotoxins; HCN is a powerful and a rapidly acting poison. It is not difficult to find plants containing these compounds in the food supply and/or in medicinal herb collections. The objective of this study was to investigate the distribution of total cyanide in nine genera (Dolichos, Ginkgo, Hordeum, Linum, Phaseolus, Prunus, Phyllostachys, Phytolacca, a...

Simultaneous determination of fluorine and chlorine in rocks by ion chromatography in combination with alkali fusion and cation-exchange pretreatment.

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...
