The analysis of plasticizers by micro-adsorption chromatography

The composition and structure of lymph chylomicrons in dog, rat, and man.

“…Individual phospholipid fractions were separated from phospholipids eluted off the silicic acid column by thin layer chromatography with silica gel G containing Ultraphor for visualization of lipid spots (12). Methyl esters of lipid fractions were prepared by heating the thin layer plate scrapings with 2% HSO4 in methanol at 650 C overnight, except in the case of sphingomyelin, for which 5% H2SO4 was employed (13).…”

Synthetic Organic Products

“…Plasticisers authorised in the USA for use in plastic package Table 146. Rsrvalues of plasticisers in various solvents, referred to dibutyl sebacate = 100 [12] No.…”

“…Compound hRfa materials for foodstuffs, have been analysed by COPIUS-PEEREBOOM [12] on silica gel G layers containing 0.005 % of the water-soluble fluorescence indicator Ultraphor-WTl. 10 (Ll amounts of approximately 5% solutions in ether of each plasticiser or equivalent extraction product were applied and developed with the solvents given in Table 146.…”
