Rapid application of samples to thin-layer chromatographic plates
Abstract
An inexpensive device for 16–21-s application of samples to thin-layer chromatographic plates is described. The reproducibility of application is comparable to that of standard methods and is adequate for quantification. Samples may be dissolved in a variety of solvents; those tested were chloroform, diisopropyl ether, ethyl acetate, butan-1-ol and plasma-water (1 + 1).
