Sepax Technologies Inc Sepax HPLC Column PolyRP-NP5, 2 x 10 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.
Sepax Technologies Inc Sepax HPLC Column HP-Silica, 3 µm, 120 Å, 4 x 10 mm
HP-Silica phase is made of activated hydroxyl (-OH) functional group with the pore size selection of 120 Å and particle size selection of 1.8, 3, 5, and 10 µm. Carbon loading is 0.0%. HP-Silica is used as the normal phase as well as HILIC phase. HP-Silica phases are suitable for separations of polar and basic organic compounds, such as vitamins, steroids, as well as pharmaceuticals.

Mac-Mod Evosphere RP18-Amide, 100 Å, 5 µm, 30.0 x 10 mm Monodisperse Fully Porous Particle Guard Cartridge
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.
Mac-Mod Princeton AMINO 60 Å, 5 µm, 2.1 x 10 mm Guard Cartridges (5/pk)
Princeton Chromatography Achiral SFC columns are designed and manufactured in the US, well known for innovating novel and robust workhorse phase chemistries, for the analysis of achiral SFC applications. Princeton designs myriad phase chemistries to improve the selectivity and efficiency of SFC analysis. Known for originally innovating the 2-EP phase chemistry, explore what Princeton has to offer. Columns are available from analytical to preparative sizes and are available in a wide range of pore sizes, particle sizes, column ID's and lengths. If you do not see something that you want, please just ask!
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.

Waters Corp XBridge BEH C8 Sentry Guard Cartridge, 130Å, 5 µm, 2.1 mm X 10 mm, 2/pk
The XBridge BEH C8 sorbent is less retentive compared to the XBridge BEH C18 sorbent. Anyone developing methods may prefer the speed offered by a less retentive column, while improving peak shape and chromatographic performance. The trifunctionally bonded sorbent offers you the widest usable pH range (1-12), superior low pH stability, and ultra-low column bleed.
