Thin Layer Chromatography - An MS Hybrid Thin Layer Plate Transport Interface for Peptide-Like Materials 4
(a) 90 fmol of Valinomycin
(b) 0.83 pmol of Cyclosporin
(c) 6.3 pmol of BOC-Phe-Lue-Phe-Lue--Phe
(d) 2,4,6 trihydroxyacetophenone used as the matrix.
The spectra obtained for four test substances are shown in figure 28. It can be deduced that the sensitivity of the somewhat involved procedure ranges from about 90 fmol to about 6 pmol.
