HPLC Guard Columns and Cartridges
YMC America, Inc HS C18 grd 120A 5um 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 Cell-SC guard 3um 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 ODS-A guard 200A 5um 10x3mm
YMC-Pack ODS-A is a high-coverage fully-endcapped C18 phase which exhibits exceptional lot-to-lot reproducibility It is available in three different pore sizes and is suitable for the separation of a wide range of compounds YMC-Pack ODS-A in 120 pore size is used for high performance reversed phase separations It has selectivity for the separation of many organic compounds found in pharmaceutical chemical and biotechnology industries 200 ODS-A offers a unique mix of moderately large pores and high surface area for the analysis of compounds ranging from small organics and pharmaceuticals to moderately-sized proteins
YMC America, Inc TMS-HG 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
YMC America, Inc TDH guard 120A 3um 20x2.1mm
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 ProC4 guard 120A 5um 10x3mm
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 ODS-AL guard 120A 5um 20x3mm
YMC-Pack ODS-AL is a non-endcapped high carbon load monomeric C18 phase It exhibits different selectivity from conventional ODS columns due to the use of not only hydrophobic interaction but also secondary interactions caused by silanol groups YMC-Pack ODS-AL is intended for use only in those situations where residual silanol activity is beneficial to the separation
YMC America, Inc Cell-SC guard 10um 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 Cell-SJ 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 CN guard 120A 5um 10x3mm
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 Holder for 10mm grds -0110CC
Guard cartridge holder for 10 mm ID YMC guard cartridges
YMC America, Inc ProC18 RS guard 80A 5um 20x3mm
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 Cell-SB 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
