Sepax Technologies Inc Sepax HPLC Column GP-C18, 3 µm, 120 Å, 4 x 10 mm
GP-C18 uses full coverage bonded silica packing, which provides exceptionally high stability. The unique mono-functional bonding chemistry of GP-C18 avoids the formation of multiple C18 layers. Such uniform stationary phase allows the separation to achieve high selectivity and high efficiency.
YMC America, Inc Cell-C guard 10um 10x10mm
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 Triart C8 grd 120A 3um 10x3mm
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 PVA-Sil guard 120A 5um 20x3mm
YMC-Pack PVA-Sil is prepared from a 5 m 120 silica support which is bonded with a monomolecular polymer coating of vinyl alcohol The polymerized PVA completely covers both external and internal surfaces of the silica support protecting it against aggressive high pH buffers and solvents
YMC America, Inc Amyl-SA guard 10um 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
YMC America, Inc YMCbasic guard 10um 10x4mm
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 TMS guard 120A 10um 10x4mm
YMC-Pack TMS columns are bonded with trimethylmonochlorosilane to create a phase with intermediate polarity This makes for a versatile stationary phase that is useful for analysis of extremely hydrophobic compounds using conventional reversed-phase solvents or highly polar compounds using high aqueous solvents The unique chemistry of this packing material is also well-suited for the analysis of multifunctional compounds Selectivity characteristics of a C1 bonded phase can be unique and samples must be evaluated to determine the applicability of the phase
Waters Corp XBridge BEH Shield RP18 Sentry Guard Cartridge, 130Å, 5 µm, 4.6 mm X 20 mm, 2/pk
XBridge BEH Shield RP18 columns complement the XBridge BEH C18 and C8 phases and provide a necessary and powerful tool for HPLC method development. The embedded carbamate group in the bonded phase ligand provides alternate selectivity, especially for phenolic compounds compared to straight chain alkyl columns.
Sepax Technologies Inc Sepax HPLC Column HP-C18, Guard cartridge with holder, 5 µm, 200 Å, 2 x 10 mm
HP-C18 uses full coverage bonded silica packing, which provides high stability.
