YMC America, Inc C8 120A 3um 100x0.3mm 1/16
YMC-Pack C8 columns are prepared using exhaustive bonding of a monomeric octylsilane to totally porous and spherical silica gels The functionalized silica is then treated with an endcapping process which produces a moderate 10% carbon loading on the standard 120 pore material Available in three pore sizes YMC-Pack C8 columns will separate many classes of compounds including pharmaceuticals organic chemicals and biologics
Mac-Mod Evosphere BIO INERT 300 Å, C4, 5 µm, 4.6 x 100 mm Monodisperse Fully Porous Particle Column in Inert-Coated Hardware
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.
YMC America, Inc C4 120A 5um 5x0.5mm 1/16
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 Diol-NP 120A 5um 50x0.3mm 1/32
YMC-Pack Diol-NP is a versatile alternative to silica for normal phase separations and provides much better reproducibility when compared to bare silica material It shows typical normal phase retention behavior when used with low-polarity mobile phases due to hydroxyl groups on the surface of the stationary phase acting as polar groups YMC-Pack Diol-NP can also be used in HILIC-mode with organic/water mobile phases
YMC America, Inc ProC8 120A 3um 100x.075mm 1/16
YMC-Pack Pro C8 columns are made using advanced endcapping technology to reduce residual silanol activity This results in excellent peak shapes for basic compounds In addition the ultra pure silica and very low residual silanol activity means that these columns frequently do not require the use of ion-pairing reagents or ion-suppression techniques making them ideal for LC/MS applications Surface hydrophobicity is lower than that of ODS making Pro C8 useful for fast analysis of compounds of greatly differing hydrophobic properties Pro C8 can also be useful for separation of hydrophilic and planar compounds in cases where resolution is hard to achieve on ODS materials

Microsolv Technology Corporation HPLC Column, HPS Cyano, 5um, 4.6mm ID x 150mm 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. This is one of our HPS Cyano Columns and compare the performance to Inertsil and Luna brands.
