Vent-free GC/MS Adapter

On sale

GC/MS interface that allows quick column exchange without venting MS to the atmosphere

Vent-free GC/MS Adapter is a simple and useful interface used for GC/MS analysis, and allows switching of a GC separation columns while the MS detector is in operation by connecting a highly deactivated capillary tube (id 0.15 mm, length 50 cm or 70 cm) between the separation column and the MS detector.
Changing columns takes only a few minutes. The Vent-free GC/MS Adapter is especially useful when a Py-GC/MS separation column and a capillary tube for evolved gas analysis (EGA) are switched between analysis using a Multi-Shot Pyrolyzer.

  • Features

  • Specifications

  • It allows fast switching of a separation column and/or an EGA tube without venting the MS detector which saves time and increases productivity.
  • When the Vent-free GC/MS Adapter is not in use, attach a plug at the end of the VF tube. This will greatly save the consumption of the carrier gas.
  • The VF tube is rugged and inert and will not absorb polar species when in use.
  • Vent-free GC/MS Adapter is easily installed by users.
