KAS4-1 Cooled Injection System (CIS)

The GERSTEL Cooled Injection System is the most widely used PTV type gas chromatographic inlet in the world. It is a true universal inlet, allowing you to perform up to 10 sample introduction techniques for gas chromatography with unsurpassed precision, accuracy and robustness, while eliminating analyte degradation, sample discrimination and septum bleed associated with hot split/splitless inlets.

The CIS ensures sample integrity while providing the lowest possible detection limits. It is the best choice for all your GC sample introduction applications, especially when combined with high resolution mass spectrometry where sample introduction can be the weak link to getting the answers you need to solve your critical challenges.

When used as a PTV inlet, the following injection modes are available

  1. Cold split liquid injection
  2. Cold splitless liquid injection
  3. Cold splitless liquid injection with solvent vent
  4. Large volume liquid injection
  5. Cool on-column liquid injection
  6. Headspace injection
  7. Multiple headspace extraction
  8. Gas sampling
  9. SPME
  10. Pyrolysis

The GERSTEL CIS can also be used as an advanced cold trap, and with the addition of Thermal Desorption and Dynamic Headspace options, doubles the number of sample introduction techniques that can be used on GC-MS platform.

  1. Thermal Desorption with TDU
  2. Headspace HIT
  4. Twister
  5. TF SPME
  6. Direct Thermal Extraction
  7. Packed tubes
  8. Micro-vial (ATEX)
  9. Dynamic Headspace
  10. Full Evaporative DHS
  11. Dynamic Headspace – Large Vessel
