Methionine Detection on Paper Chromatograms.

The Identification of Streptomycin on Paper Strip Chromatograms.

Separation and estimation of organic acids on paper chromatograms.

Spray detection of phospholipids on thin-layer chromatograms.

A new spray reagent with copper, ammonium molybdate, and sulphuric acid for the detection of phospholipids on thin-layer chromatograms is described. The specificity and sensitivity of the spray reagent is also shown.

A new reagent for detection of peptides, nucleotides, and other N-H-containing compounds on paper chromatograms.

The detection of small quantities of nitrogen-containing compounds on paper chromatograms is a problem of long standing interest. The ninhydrin technique, first introduced by Consden, Gordon, and Martin (l), has partially solved this problem and has proven to be extremely valuable. However, the narrow range of compounds detected, the decreased sensitivity with increased molecular weight of pept...
