Abstract:
Monocyclic aromatic solvents like benzene, p, m, o-xylenes, styrene, ethylbenzene, etc., are derived from reformates or synthesized, and therefore may contain reaction intermediates/unreacted starting material or other residual compounds. Determination of purity is vital for many labs since they are used as a starting component in synthesis of different plastics, drugs, insulation, shoes, cars, to name a few. Purity analysis by ASTM D7504 method is performed using a long polar column that separate un-retained non-polar hydrocarbons from aromatic hydrocarbons which are then individually reported. Faster analysis can be achieved using more efficient, shorter and narrower bore column. However, to meet the resolution requirements and minimum limits of detection, the sample loading capacity should be considered. Presented is our solution for switching to a shorter narrower bore column.
