Protect your expensive GC column from damage, improve productivity and reduce gas costs.

Our Triple Gas Filter provides improved gas quality for maximum protection, improved productivity and significant gas savings. Clean gases extend column life, improve sensitivity, and reduce instrument downtime. Contaminants in gases can significantly impact your analysis. Oxygen, hydrocarbons and moisture can cause loss of sensitivity and accuracy of the GC, and damage your column. Installing a Triple Gas Filter in the gas line immediately before the instrument inlet greatly reduces the level of impurities, thus improving trace analysis. Contaminants entering your GC column will also be reduced, which is critical for high temperature analysis and essential for longer column lifetime.

Replacing the filters when they have reached absorption capacity ensures maximum protection of your GC columns and analytical hardware. The sensitive indicators change color, alerting you that the filter needs to be replaced.

A Triple Gas Filter allows you to use 99.996% pure helium instead of the more expensive 99.999% or 99.9999% grade, while still yielding high quality analytical results. This can save up to 30% per instrument in gas expense.
