DB-225ms Columns

J&W DB-225ms GC columns deliver excellent low-bleed performance in a variety of applications and are QC tested to exacting industry standards in terms of accuracy and reproducibility of results. They are bonded, crosslinked, solvent rinsable, and low bleed, and are precision engineered for efficient separation of cis- and trans-fatty acid methyl esters. A close equivalent to USP phase G7, this mid- to high-polarity column is operational from 40 to 240 °C.
