DB-225ms is excellent for FAME separations and is bonded, cross-linked, and operates from 40 to 240 °C.

• Virtually equivalent to (50%-Cyanopropylphenyl)-methylpolysiloxane
• Mid/high polarity
• Excellent for separations of cis- and trans-fatty acid methyl esters (FAMEs)
• Low bleed
• Bonded and cross-linked

J&W DB-225ms 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. These columns are bonded, cross-linked and low-bleed, and have been precision-engineered to be perfectly suited for efficient separations of cis- and trans-fatty acid methyl esters. The mid- to high-polarity DB-225ms columns are operational from 40 to 240 °C and are also solvent rinsable.
