HPLC Guard Columns and Cartridges
Waters Corp µBondapak C18 Radial-Pak Guard, 125Å, 10 µm, 40 mm X 10 mm, 2/pk
µBondapak C18 columns are general purpose, silica-based, reversed-phase C18 columns that are based on 10 µm particle technology. As a starting point for preparative chromatography, no other column can provide the balance between resolution, throughput and cost.
Waters Corp Porasil Silica Radial-Pak Column, 125Å, 15 - 20 µm, 25 mm X 100 mm, 1/pk
Waters Porasil 15 - 20µm silica packing material provides long column life and low backpressure. The packing also has a high surface area making it ideal for preparative work.
Waters Corp XBridge BEH C18 Sentry Guard Cartridge, 130Å, 3.5 µm, 4.6 mm X 20 mm, 2/pk
As a workhorse for HPLC method development, XBridge BEH C18 sorbent can be used over an entire range of mobile phase pH (1-12). The trifunctionally bonded C18 ligand provides you with a universal column for most HPLC separations and gives you the widest usable pH range, superior low pH stability, and ultra-low column bleed.
Waters Corp XBridge BEH C8 Sentry Guard Cartridge, 130Å, 3.5 µm, 3 mm X 20 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.

Mac-Mod Princeton PFP 100 Å, 5 µm, 21.2 x 10 mm Guard Cartridges (1/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!
Mac-Mod Evosphere AQ, 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.
