Cooled Injection System

Internationally the most frequently used PTV-type universal inlet, with patented septumless sampling head.

Gas chromatographic analysis is now more versatile, reproducible and has lower detection limits than ever before, thanks to temperature programmed sample injection using GERSTEL Cooled Injection System.

The GERSTEL CIS provides two essential system-functions:

  • Universal injection system for all injection techniques: split, splitless, on-column and large-volume up to 1000 µl.
  • Cryotrap enrichment system in combination with sample preparation systems, for example, the GERSTEL Thermal Desorption System TDS, the GERSTEL Dynamic Headspace DHS, the GERSTEL Thermal Desorption Unit TDU or the GERSTEL MultiPurpose Sampler MPS.

The CIS is easily and conveniently controlled from the GERSTEL MAESTRO Software – stand alone or through the Agilent Technologies ChemStation software.
