VF-DA Columns

Agilent J&W VF-DA is a unique, guaranteed low-bleed column for forensic drug confirmation testing. The column has high recovery for trace components and excellent resistance to direct methanol injections.;Most general screenings for forensic drugs are performed in a variety of matrices, using full-scan GC/MS (EI). Since column bleed can negatively influence detection limits in full-scan mode, the exceptional low bleed of this column is critically important for achieving reduced detection limits, improved accuracy, and a cleaner detector.
