[The use of a thin-layer chromatographic method for measuring the concentrations of mixtures of the dyes scarlet 2G and black 2K in the air of a work area].
Scarlet 2G and black 2K dyes were divided and measured by thin-layer chromatography with mixture of acetone and toluene (3:4) used as an eluent for dividing scarlet 2G and a mixture of chloroform, benzene and acetone (3:2:1) for eluting black 2K. The method permits the detection of the aforesaid dyes in the air of working area at the level of 0.5 MAC in the presence of admixtures.
