The MDA contents in the SAT samples were determined after saponification followed by derivatisation
according to methods described by Czauderna et al.
An attempt was made to detect small peptides and amino acids in a similar gel that was modified to 15% acrylamide to favour separation of smaller peptides, by derivatisation
of carboxylic acid moieties with the fluorescent dye PDAM (1-pyrenyldiazomethane).
20 Pre-column derivatisation
of free L-carnitine was done by p-bromophenacyl bromide to form its ultraviolet absorbing ester.
of plates was performed through dipping (Speed: 3, dme:0) with 10% sulphuric acid in methanol reagent using CAMAG Chromatogram Immersion Device and heated to 100[degrees]C for 5 min on the TLC plate heater.
Gas chromatography involves saponification and derivatisation
of the fatty acids in the thermally induced trilinolein samples and separation of the methyl esters using a high resolution capillary column that is suitable for the separation of cis and trans isomers.

Contract Awarded for Purchase of a Post-column Derivatisation
Concentrations of amino acids were determined using pre-column derivatisation
amino acid analysis with 6-aminoquinolyl-N-hydroxysuccinimidyl carbamate followed by separation of the derivatives and quantification by reversed phase high performance liquid chromatography according to Cohen and Michaud (1993) and Cohen (2001).
