Ores (sodium carbonate fusion in Pt0 followed by HCl dissolution - blank levels of Li in sodium carbonate critical)
GC column, LIPODEX D, 25 m L, 0.25 mm ID, proprietary df 5190-2277 Me-Sil is more inert thanCapillary columns for GC enantiomer separation. LIPODEX cyclodextrin phases are made of cyclic oligosaccharides consisting of six ( cyclodextrin), seven ( cyclodextrin) or eight ( cyclodextrin) glucose units bonded through 1,4 linkages. Regioselective alkylation and or acylation of the hydroxyl groups leads to lipophilic phases with varying enantioselectivity, which are well suited for chiral analyses. Important advantage many compounds can be
