WebAnother example of the impregnation approach to the chiral TLC separations involves the impregnation of diol-bonded HPTLC plates with the chiral ion pair reagent N-benzoxycarbonyl-glycyl-l-proline (ZGP). These plates are prepared by first washing with dichloromethane, then dipping in a 4 mmol L −1 solution of ZGP and 0.4 mmol L −1 ... WebThin-Layer Chromatography. A TLC plate is a thin sheet of solid adsorbent (usually silica or alumina) spotted with known and unknown substances. From: Demystifying Explosives, 2015. ... There have also been several examples of the use of chiral IP reagents for the separation of enantiomers.
