Larger porous shell particles with narrow particle size distribution, used in Supelco's BIOshell™ columns for the reversed-phase U/HPLC analysis of peptides and proteins, provide increased efficiency per unit pressure drop.
Pesticide residue testing of turmeric and other (dried) spices is challenging due to their complex compositions and high matrix. An efficient SPE clean-up can be achieved by a new Dual-layer cartridge.
Two metabolic pathways exist for the biosynthesis of isopentenyl pyrophosphate and dimethylallyl pyrophosphate: The mevalonate pathway, predominantly used by plants and in a few insect species. The non-mevalonate pathway or methyl D-erythritol 4-phosphate (MEP) pathway, which occurs in plant chloroplasts

Phosgene is 170 times more reactive than TP, the main phosgene substitute. Therefore, reactions with phosgene can be carried out under much milder conditions than with TP. Compounds will react faster and at lower temperatures (often at -78°C), preserving sensitive
