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.
