SecurityGuard Column Protection
Column Protection
A common cause of high backpressure, split peaks, broad peaks, baseline noise, baseline drift, and loss of resolution is contaminants. All mobile phases contain some chemical contaminants or micro particulates, from the sample, solvent, or wear on the polymeric seals of the pump or injector. These contaminants can clog frits, irreversibly bind to columns, degrade performance, and even damage the flow cell. An easy solution, SecurityGuard is a universal column protection system designed to effectively (and inexpensively), protect your valuable columns, from the damaging effects of chemical contaminants, without altering your chromatographic results.
- Protects chromatographic results
- Extends UHPLC, HPLC, SFC, and PREP column lifetime
- Virtually no change in chromatography
- Simple to use
- Saves time and money
- Compatible with virtually all vendors columns

Overview
Removes Harmful Contaminants and Particulates
It’s a fact! Chemical contaminants and particulates are a natural part of any chromatographic analysis. The easiest way to extend column performance is to remove these contaminants and particulates with the SecurityGuard™ Cartridge System before they reach your column and degrade your chromatography damaging overtightening.

Protect Any Column
Compatible HPLC Fittings
Installing the SecurityGuard protection system into your favorite column is easy. The floating outlet from the SecurityGuard holder automatically adjusts to the precise depth of virtually every manufacturer’s column. This ensures a low dead volume, leak free connection, without the use of unions or adapters, no matter which manufacturer’s column you are using.
Longer Column Lifetimes
Keep Columns Performing Their Best
When contaminates and particulates build up at the head of the column or on the guard cartridges, system pressures dramatically increase. Simply replace the SecurityGuard cartridge instead of your column and you are able to regain normal operating conditions and reclaim original column performance.
Accelerated column lifetime test
In this accelerated column lifetime test, the UHPLC column lasts substantially longer with SecurityGuard ULTRA guard cartridge system.
SecurityGuard Standard Performance
Accelerated lifetime test using endogenous biomolecule matrix on a reversed phase C18 column, 5 μm, 50 x 4.6 mm with SecurityGuard Standard C18 cartridges. Backpressuare values represent additional backpressure contributed by SecurityGuard Standard.
Maintain Column Performance
Virtually No Change in Chromatography
SecurityGuard ULTRA maintains UHPLC column performance without altering chromatographic results. The extremely low dead-volume (<0.3 µL) of this unique guard design minimizes peak dispersion ensuring that ultra high efficiency chromatography is maintained. Unlike competitors’ UHPLC guard systems, SecurityGuard ULTRA has virtually no effect on efficiency, retention time, or backpressure. This leads to longer column lifetime with no loss in column performance.

PREP HPLC Column Protection
Protect Your Purification Results
The SecurityGuard PREP system was designed to effectively and inexpensively protect your valuable prep columns from the damaging effects of mobile phase and sample chemical contaminants and particulates, without altering your chromatographic results.
- Extends preparative column lifetime by as much as 5 times
- Protects column from samples that precipitate out of solution
- Protects column from contaminants
- Stable and leak free up to 60 mL/min within specified pressure ratings
Lower Cost Per Injection
SecurityGuard isn’t only about column protection, it’s about lowering your cost per injection! When you increase the number of injections from a single preparative column you’re lowering your overall cost per injection. With SecurityGuard PREP, the inexpensive cartridge was ruined while the integrity of the prep column was maintained and its performance restored.
