Extends UHPLC, HPLC, SFC, and PREP column lifetime

SecurityGuard Guard Cartridge System Column Protection is designed to fit any manufacturers’ standard HPLC column, making it the ultimate HPLC Guard Column.   SecurityGuard Guard Cartridge System is guaranteed to extend the lifetime of your 2.0 mm, 3.0 mm, 3.2 mm, 4.6 mm, and 7.8mm ID column by capturing sample contaminants that can cause an increase in backpressure and effect baseline noise.     Features:…

Universal fit to virtually all manufacturers’ analytical columns Saves expensive columns and equipment from damaging microparticulates Convenient, disposable in-line filter There are two types of KrudKatchers depending on system backpressure and dead volume demands: KrudKatcher Classic The PEEK filter body of the KrudKatcher Classic houses an integrated 2.0 µm 316 stainless steel depth filter that efficiently…

SecurityGuard offers a convenient and economical way to extend HPLC column lifetimes. Did you know a common cause of high backpressure, split peaks, broad peaks, baseline noise, baseline drift and loss of resolution is contaminants? The fact is all mobile phases contain some chemical contaminants or microparticulates, from the sample, solvent, or wear on the polymeric seals of the pump or injector. These contaminants can…

The EXP® Pre-Column Filter is ideal for protecting small-particle UHPLC columns at extreme pressures. Such techniques analyze samples in the most demanding applications, which can decrease the life of these expensive columns. EXP® Pre-Column Filters help extend that life and protect your column investment without sacrificing performance. Free-Turn® architecture allows the user to change cartridges by hand without breaking flui…

OPTI-GUARD® 1mm Guard Columns set 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® requ…

 The qEV10 / 35nm is designed for separating exosomes from a 10mL biological sample and comes with Luer Lock fittings.

Use Micro-Guard Cation H Cartridges to protect any Aminex H-form HPLC Column.

Perform derivatization and other small-scale reactions reliably and with ease using the Thermo Scientific™ Reacti-Therm™ Heating and Stirring module.

Widely considered the premium columns for analyzing biopolymers by GFC, TSKgel G2000SWXL, 5 μm columns are an excellent choice for small proteins and peptide separations.

The TSKgel Alpha-4000 column is packed with rigid, porous polymer beads which show minimal shrinkage or swelling in polar organic solvents (methanol, acetonitrile, DMSO, isopropanol, THF, and HFIP). This column is stable in a wide variety of organic solvents at concentrations up to 100%.

Extend your LC column lifetime while maintaining chromatographic performance.

VanGuard Pre-Columns for UPLC® separations are guard columns that are designed for use with the ACQUITY UPLC® system. These guard columns use an ultra-low volume design (patent pending) that efficiently protects UPLC column performance. This ultra-low volume design does not compromise the UPLC holistic design approach to higher efficiency, greater resolution and increased throughput. Guard columns are typically used in appli…

HisTrap FF is a ready-to-use column, prepacked with precharged Ni Sepharose 6 Fast Flow for preparative purification of histidine-tagged recombinant proteins by immobilized metal ion affinity chromatography (IMAC).

The EXP® Guard Column cartridge system is rated to 15,000 psi with hand-tight replaceable cartridges. This unique design connects directly to any UHPLC column with the auto-adjusting Titanium Hybrid Ferrule and EXP® Fittings, providing repeated zero-dead-volume connections and easy adjustability between various column types. Free-Turn¨ architecture allows the user to change cartridges by hand without breaking fluid connections…

As an alternative to conventional columns, PharmaFluidics offers micromachined nano-LC columns or micro Pillar Array Columns (µPAC™). These µPAC™ columns display exceptional separation properties with unprecedented peak capacity and narrow peak shapes at low operating back-pressure. µPAC™ column, 200 cm length, with pillar array backbone at interpillar distance of 2.5µm, C18.

The UNIGUARD drop-in cartridge fits both our guard systems: the stand alone UNIGUARD and the Direct Connection UNIGUARD. Product detail: We recommend all analytical columns are protected by a guard cartridge, which is replaced on a regular basis. The ID of the analytical column determines the correct ID for the guard cartridge. We offer 10x1.0, 10x2.1, 10x3.0, 10x4.0 (for use with both 4.0 and 4.6mm ID analytical columns) i…
