Varian FactorFour™ Capillary Columns: Features

The FactorFour™ line stands alone. With an average bleed specification one-fourth the measurable bleed of other so-called ultra low bleed columns, no competitor even comes close. Offering the lowest bleed specifications available, column bleed is minimized so all the benefits of low bleed are provided:

increased sensitivity.
 
Less spectral interference from bleed ions results in more accurate and reliable confirmations.
 
Faster stabilization leading to more uptime of your equipment.
 
Reduced detector contamination leading to higher throughput
