YMC America, Inc ProC18 guard 120A 3um 10x3mm
YMC-Pack Pro C18 columns start with a tightly controlled highly purified silica gel followed by a high-coverage C18 bonding and finished with a unique endcapping procedure utilizing Lewis acid/Lewis base chemistry Together these features provide unequaled separations with sharp and symmetrical peaks for all types of organic molecules especially basic pharmaceuticals and chelating compounds
YMC America, Inc YMC Carotenoid grd 5um 20x3mm
YMC Carotenoid is a C30 bonded silica-based reversed phase column that is markedly more hydrophobic than classical C18 phases Even when pure organic eluents are applied many sample solutes are retained The YMC Carotenoid C30 stationary phase provides sufficient phase thickness to enhance interaction with long chain molecules therefore geometric and positional isomers of conjugated double-bonding systems are recognized and resolved It can be used to separate carotenoids in blood samples food products natural product extracts and commercial preparations In addition YMC Carotenoid operates with low aqueous or non-aqueous mobile phases that are desirable in LC/MS and prep fraction recovery
