HPLC Guard Columns and Cartridges
Sepax Technologies Inc Sepax HPLC Column GP-C18, Guard cartridge with holder, 5 µm, 120 Å, 2 x 10 mm
GP-C18 uses full coverage bonded silica packing, which provides exceptionally high stability. The unique mono-functional bonding chemistry of GP-C18 avoids the formation of multiple C18 layers. Such uniform stationary phase allows the separation to achieve high selectivity and high efficiency.
Optimize Technologies OPTI-GUARD™ Biocompatible 1mm Guard Column, Cation Exchange (SCX), 5pk
OPTI-GUARD™ sets the standard for extremely low impact, easy to use pre-column protection. Designed for use with analytical (4.6, 3.0 mm i.d.) and narrow-bore (2.1, 1.0 mm i.d.) columns, the patented floating stem design automatically adjusts to any manufacturer's tube stop depth for a zero-dead-volume connection every time. The best part? It's no larger than a standard fitting. Connecting the OPTI-GUARD™ requires no extra tubing, maintaining the minimal impact philosophy that has made the OPTI-GUARD™ line so popular. As always, custom packing is available. Key Features include: 5 disposable hand-tight holders and cartridges, a ZDV Connection, automatic adjusting to any manufacturer's column, no extra tubing is required for connection, the product does not effect chromatography, and it is no larger than a standard fitting.
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.

CN30S05-02Q1GC: Cyano, 5um, 300A, 20X2.1mm Cartridge, pk/5
Mac-Mod Princeton Benzamide 100 Å, 5 µm, 10 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 Waters Prep Guard Cartridge, CSH C18, 5 μm
This XSelect CSH C18 Prep Guard Cartridge offers alternative selectivity compared to other C18 sorbents, utilizing Charged Surface Hybrid (CSH) technology to improve peak shape and loading for basic compounds. It provides enhanced column protection by acting as a barrier against contaminants and contains the same packing material as the analytical column.
