J. Biochem. (Tokyo) 107, 685-688 (1990). Identification of blood group A-active glycosphingolipids from human erythrocyte membranes by the combination of TLC and matrix-assisted secondary ion mass spectrometry (TLC/SIMS). Detection by TLC-immunostaining assay using anti-A antibody. Presentation of detailed information, such as molecular weight, molecular species, ceramide portion, and oligosaccharide sequence.

J. Planar Chromatogr. 3, 359-361 (1990). HPTLC of phytoecdysteroids on silica with chloroform - ethanol 4:1. Detection by fluorescence quenching at 254 nm. Mass spectra directly from the aluminium-backed silica gel TLC plate. The coupling of TLC with off-line MS-MS without the need for prior elution of the separated ecdysteroids provided significant additional information on the molecular structure of the ecdysteroids compared with previous studies employing only TLC-FAB-MS.

J. Planar Chromatogr. 7, 344-348 (1994), Use of AMD for the improvement of the identification and determination limit by FTIR of hexobarbital to between one half and one third of their original values; AMD can be recommended for such application. When thinner silica gel layers on a reflecting carrier are used, these values can be reduced once again (by half). In order to achieve optimum results, certain procedures must be followed: dot spotting and mobile reference measurement taken at the level of the substance to be analyzed. Detection limits for hexobarbital = 55 ng, phenobarbital = 55 ng, caffeine = 30 ng, salicylic acid = 220 ng and ascorbic acid = 240 ng. The reasons for and significance of these different limits of identification are discussed.
