VF-DA

VF-DA from Agilent Technologies

Agilent J&W VF-DA is a unique, guaranteed low-bleed column for drugs of abuse confirmation testing. The column has high recovery for trace components and excellent resistance to direct methanol injections. Drugs of abuse are measured in a variety of matrixes. In urine, most general screenings are performed using full-scan GC/MS (El). Since column bleeding can negatively influence detection limits in full-scan mode, the exceptional low bleed of VF-DA columns is critically important. Low bleed are provides reduced detection limits, improved accuracy, and a cleaner detector
