YMC America, Inc Triart C18 grd 120A 5um 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 Cell-SC 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
YMC America, Inc Jsphr H80 grd 80A 4um 10x3mm
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 CN guard 120A 20um 10x10mm
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 C4 guard 300A 3um 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 TriBioC4 300A 1.9um 5x2.1mm
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 ODS-AM guard 120A 3um 10x4mm
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 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 ODS-AL guard 120A 3um 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
