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…
