HPLC Guard Columns and Cartridges
YMC America, Inc Holder for 10mm grds -0110CC
Guard cartridge holder for 10 mm ID YMC guard cartridges
YMC America, Inc Jsphr L80 grd 80A 4um 20x3mm
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 HS C18 grd 120A 3um 20x3mm
Hydrosphere C18 is based on highly inert ultra-pure pH neutral silica and is designed to maintain a hydrophilic surface for superior separation of hydrophilic compounds Minimal metal content and very low concentrations of residual silanols make this an ideal phase for the analysis of basic pharmaceuticals and chelating compounds even under LC-MS conditions such as separation in non-phosphate buffered systems In addition the ability to separate polar compounds under highly aqueous mobile phase conditions without loss in retention plate counts and peak performance greatly enhances the versatility of Hydrosphere C18
YMC America, Inc YMCbasic guard 3um 10x3mm
YMCbasic is a unique reversed-phase column designed for analysis of pharmaceuticals and basic compounds Innovative silica synthesis and state-of-the-art silane bonding result in a chromatographic material with neutral silanols This minimizes interactions with both basic and acidic compounds
YMC America, Inc Cell-C guard 5um 20x2.1mm
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 PolyamII grd 120A 5um 20x3mm
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
YMC America, Inc Ph guard 120A 5um 10x3mm
Phenyl columns provide unique selectivity when compared to aliphatic straight chain reversed phase materials such as C18 C8 and C4 YMC-Pack Phenyl is a monomerically-bonded phenyl and is fully endcapped Typical applications include aromatic compounds phenols fullerenes sweeteners
YMC America, Inc NH2 guard 120A 5um 20x3mm
YMC-Pack NH2 is a normal phase separation column utilizing the polarity of primary amino groups bonded to silica It is a versatile stationary phase often used for the separation of sugars but can also be used for separations utilizing weak anion-exchange
YMC America, Inc Triart C8 120A 3um 10x2.1mm
YMC-Triart phases are based on organic/inorganic hybrid particles that combine the high mechanical stability and efficiency of a silica-based packing material with the robust chemical stability of a polymer-based packing material This versatile resin is produced using tightly controlled particle formation technology adapted from micro-reactor technology The resulting uniform particle and pore size distributions as well as the smooth surface greatly contribute to excellent peak shape and separation reproducibility In addition YMC-Triart materials are highly resilient and robust when used at extreme pH elevated temperature and high pressure
YMC America, Inc Cell-C guard 3um 20x4mm
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
