Guard columns are a simple yet highly effective way to protect your valuable analytical and preparative columns. By capturing particulates, strongly retained compounds, and contaminants before they enter the main column, guard columns prevent blockages, minimize peak distortion, and maintain reproducible performance over time.
Using guard columns significantly extends the lifetime of your main column, reducing the need for frequent replacements and lowering overall operating costs. They are easy to install, cost-efficient, and available in different dimensions to match your analytical or preparative setup.
For laboratories aiming at reliable results and maximum value from their chromatography systems, guard columns are the smart investment in long-term performance.
Protect and Prolong. Analytical guard columns safeguard your main column from particulates and contaminants, ensuring consistent performance, reproducible results, and extended column lifetime – all at minimal cost.
Protection at Scale. Preparative guard columns shield your main prep hardware from particulates and strongly retained impurities, extending lifetime and preserving separation performance. They offer an easy, economical way to reduce downtime, lower operating costs, and ensure reproducibility in large-scale purification.
Tailored Protection for Mid-Bore Applications. Specifically designed for 8 mm ID analytical and semi-preparative columns, these guard columns efficiently trap particulates and contaminants before they reach the main column. The result: extended column lifetime, reduced replacement costs, and reliable performance across demanding applications.
Universal Protection for Multiple Column IDs. All-Guards offer a flexible and economical way to protect your analytical columns. Designed for use with 2.1 mm, 3.0 mm, and 4.6 mm ID formats, these cartridge-based guard systems trap particulates and contaminants before they reach the main column.
Efficient Pre-Concentration and Protection. Trapping cartridges capture particulates and strongly retained impurities before they reach the analytical column, improving sensitivity and extending column lifetime. Available in multiple formats, they provide a simple, economical way to stabilize nano LC-MS workflows and ensure reliable performance.
