Chromatography Columns and Cartridges
YMC America, Inc Amyl-SA guard 3um 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 ODS-AM guard 120A 5um 20x3mm
YMC-Pack ODS-AM is produced with specific emphasis on lot-to-lot reproducibility of the packing material Strict manufacturing control is performed on all aspects of quality including physical properties of the silica base gel as well as surface modifying processes ensuring exceptional reproducibility
YMC America, Inc ProC18 RS guard 80A 3um 10x3mm
YMC-Pack Pro C18 RS exhibits elevated recognition of stereoselectivity due to high carbon trifunctional bonding Columns maintain a strong resistance to acid and alkali and the separation selectivity for compounds that differ only slightly in hydrophobicity is outstanding In addition extensive endcapping of the stationary phase results in excellent peak shape for basic compounds
YMC America, Inc C8 guard 120A 3um 20x3mm
YMC-Pack C8 columns are prepared using exhaustive bonding of a monomeric octylsilane to totally porous and spherical silica gels The functionalized silica is then treated with an endcapping process which produces a moderate 10% carbon loading on the standard 120 pore material Available in three pore sizes YMC-Pack C8 columns will separate many classes of compounds including pharmaceuticals organic chemicals and biologics
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 CN-HG guard 120A 20um 50x30mm
YMC-Pack CN can be used for both normal phase and reversed phase analyses due to the medium polarity of the cyanopropyl phase bonded to the silica base particle It can be used in normal phase with low-polarity mobile phases such as hexane or in reversed phase with highly-polar mobile phases such as methanol and water YMC-Pack CN can be useful for shortening analysis time in situations where retention is substantial using C18 or C8 or when separation optimization is difficult
YMC America, Inc Diol guard 200A 3um 20x4mm
YMC-Pack Diol is a size exclusion chromatography column packed with dihydroxypropyl-bonded silica and available in four different pore sizes It exhibits high mechanical strength and is useful for molecular weight determination of proteins and sugars The 2 m and 3 m particle sizes provide high resolution and fast analysis
YMC America, Inc Jsphr L80 grd 80A 4um 10x4mm
The J sphere series of columns consists of three kinds of ODS made from the same silica gel base each with a different ligand coverage The 4 um 80 silica support provides outstanding chromatographic efficiency while the high surface area material (500 m2/g) offers exceptional interaction with analytes This combination provides excellent peak symmetry across all J sphere products The variations in ligand coverage produce three columns with different hydrophobicity hydrogen bonding capacity and steric selectivity for tertiary structures Because of this J sphere can be used with confidence to identify structural differences of solutes and to improve the efficiency of separation optimization

YMC America, Inc ProC4 guard 120A 5um 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 The wide pore butyl chemistry allows minimal distortion of tertiary conformation for large biomolecules and results in samples that are pure concentrated and high in biological activity
YMC America, Inc PolyamII grd 120A 5um 10x3mm
YMC-Pack Polyamine II is a silica-based normal-phase stationary phase bonded with polyamine that is particularly useful for the separation of sugars The column lifetime in aqueous mobile phases is longer than conventional silica-based amino columns and is therefore applicable for the separation of oligosaccharides using high-aqueous mobile phases In addition YMC-Pack Polyamine II can be used to separate ionic compounds with a combination of normal-phase and weak anion-exchange modes
