Rxi GC Columns

All Rxi® columns are guaranteed to exhibit reliable column-to-column reproducibility and low bleed because we individually test every column for inertness, selectivity, film thickness, efficiency, and bleed—measuring the results against strict QC specifications. Rxi® columns are never batch tested. The critical performance values, including bleed, that we obtain with our tests are listed on the chromatographic test report included with your Rxi® column. Every Rxi® column that leaves our facility has been proven to meet or exceed the most stringent requirements.
