Detection in chromatography

Numerous redox reactions are used for detection in thin-layer and paper chromatographies. 

This reaction is also used for the characterization of peptides. Treating the thin layer (after migration) by sodium hypochlorite gives N-chloroamide groups in place of the initial peptide bonds  

3 Titration Reactions for Which the Equivalence Point Is Detected Through the Occurrence of a Redox Reaction 

Under this heading, titration reactions themselves are not redox ones or, in any case if they are, are not implicated in the detection of the equivalence point. One example is given by the method sometimes called nitritometry evoked in connection with the indirect iodometry. Nitrous acid in excess appearing once the equivalence point is reached during the titration of aromatic primary amines is detected by the formation of bromine. Bromide ions, added in the medium before the beginning of the titration, are indeed oxidized by nitrous acid in excess. The titration reaction itself is 

At the equivalence point, the following redox reaction occurs

Also low pressure ICPs and MIPs, often used as ion sources (see e.g. Creed et al. [606]) are very similar in their performance to glow discharges, except for them being electrodeless discharges. They have shown particular merits for element-specific detection in chromatography, where detection limits down to the pg/s level...

Birks has recently prepared a monograph on chemluminescence and photochemical reaction detection in chromatography which is likely to be of particular interest to analytical chemists. Few papers on chemiluminescence have appeared in the mainstream chemical literature. A significant exception is a theoretical treatment of the mechanism of the chemiluminescent decompositon of 1,2-dioxetanes . A series of phenyl N-alkylacridinium 9-carboxylates have been synthesised and their chemiluminescent properties evaluated. ...
