Agilent DB-35ms Ultra Inert GC Columns

Agilent J&W DB-35ms Ultra Inert is a mid-polarity column for applications where different selectivity is needed for enhanced separations, including pesticide analysis and drugs of abuse testing. This column quantifies components at a lower level, with broader linearity and optimized separation, ultimately increasing productivity.
