YMC America, Inc TriC18 120A 1.9um 150x.5mm1/16
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 NH2 120A 5um 100x0.5mm 1/32
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 YMCbasic 3um 100x0.3mm 1/16
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 SIL 60A 5um 50x0.3mm 1/32
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 Amyl-C Neo guard 5um 10x30mm
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-AHG col 120A 20um 500x30mm
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

Microsolv Technology Corporation HPLC Column, HPS Cyano, 5um, 4.6mm ID x 250mm Length, 120A. 1 EA.
This Cogent HPS Cyano™ Stationary Phase has been a premium value and used by HPLC laboratories for many years. It is fully end capped and is manufactured with a mono functional, 3 carbon ligand that has an attached terminal Cyano (Carbon & Nitrogen) group which includes a triple bond, and it is bonded to our 120A High Purity Silica, making this Column ideal as an Alternate in USP Methods that use the L10 Classification or for new Methods. With a 5 µm Particle, this Column works well with higher flow rates and lower back pressures compared with smaller Particles. It is often used for polar or neutral compounds in Reversed Phase HPLC and you should expect shorter retention times and faster equilibration ( between runs ) than with a non-modified, Silica Column. Compare the performance to Inertsil and Luna brands.
Sepax Technologies Inc Sepax HPLC Column PolyRP-1000, 10 µm, 4.6 x 30 mm
GP-C8 phase is synthesized with monomeric and fully endcapped chemistry. The uniform octyl stationary phase allows high efficiency with lower hydrophobicity compared to ODS phase. GP-C8 phase is suitable for separating compounds with a wide range of hydrophobicity. It is highly recommended for separating the compounds which are too strongly retained on C18 phases.
Mac-Mod Evosphere AQUA, 100 Å, 1.7 µm, 0.15 x 150 mm Monodisperse Fully Porous Particle HPLC Column
Evosphere UHPLC and HPLC columns are 100 A Monodispersed Fully Porous Silica-based columns designed to combine the benefits of Fully Porous and Core-Shell particle technology into an improved particle design and morphology that brings cutting-edge loading capacity to ultra-high-resolution particle columns. The Monodispersed Particles provide similar efficiency to Core-Shell products when comparing them directly via particle size matching and significantly increase loadability which allows ultra-high resolution analytical separations to scale to preparative separations for isolation work if needed. The bonded phase chemistries are exciting as well to maximize selectivity with novel C12 bonded phase, 2 multi-modal C18/AR, and C18/PFP bonded phases, an extended and stabilized phenyl funtionality in the Diphenyl bonded phase, a polar endcapped AQUA phase, a Phenyl-Hexyl phase, a propyl PFP phase and the RP18-Amide bonded phases which is great for doing bases at low pH.
