HPLC Guard Columns and Cartridges
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 3um 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

YMC America, Inc Cell-C guard 5um 10x4mm
YMC s CHIRAL ART series features polysaccharide-derived chiral stationary phases (CSPs) based on amylose and cellulose tris-carbamate derivatives available in both coated and immobilized formats These columns provide exceptional stereoselectivity durability and solvent versatility supporting normal-phase reversed-phase and supercritical fluid chromatography (SFC) modes
YMC America, Inc SIL guard 120A 3um 10x3mm
The high-purity silica found in YMC-Pack SIL columns provides virtually complete sample recovery The absence of silica impurities reduces non-specific sample adsorption and the totally porous nature of the silica provides high sample loading The elevated chemical purity of YMC silica results in a particle structure exhibiting high mechanical strength YMC-Pack SIL is suitable for separation of fat-soluble compounds using non-polar mobile phases as well as the separation of positional isomers that are difficult to separate in reversed-phase mode SIL-06 (60 pore size) has greater adsorption properties than SIL (120 pore size) due to its larger surface area and is generally useful for separating natural products with low molecular weight
YMC America, Inc C4-HG guard 120A 10um 10x4mm
YMC-Pack C4 is ideal for analyzing mixtures with a wide range of component polarity This is due to the C4 bonded phase exhibiting shorter analysis time while still maintaining high resolution when compared to longer-chain bonded chemistries YMC-Pack C4 (Butyl) columns are available with three pore sizes to accommodate optimum separations of virtually any molecular-weight compound The 120 phase is used extensively with non-polar peptides which are too strongly retained on C8 and C18 The 200 and 300 phase columns effectively resolve many classes of proteins and biopolymers
YMC America, Inc Cell-SB guard 10um 10x30mm
YMC s CHIRAL ART series features polysaccharide-derived chiral stationary phases (CSPs) based on amylose and cellulose tris-carbamate derivatives available in both coated and immobilized formats These columns provide exceptional stereoselectivity durability and solvent versatility supporting normal-phase reversed-phase and supercritical fluid chromatography (SFC) modes

YMC America, Inc ProC8 guard 120A 3um 10x3mm
YMC-Pack Pro C8 columns are made using advanced endcapping technology to reduce residual silanol activity This results in excellent peak shapes for basic compounds In addition the ultra pure silica and very low residual silanol activity means that these columns frequently do not require the use of ion-pairing reagents or ion-suppression techniques making them ideal for LC/MS applications Surface hydrophobicity is lower than that of ODS making Pro C8 useful for fast analysis of compounds of greatly differing hydrophobic properties Pro C8 can also be useful for separation of hydrophilic and planar compounds in cases where resolution is hard to achieve on ODS materials
