Review date: 16 May 2014 | GERSTEL Cooled Injection System 4
The CIS 4 is the most widely used PTV inlet in the world. It is designed specifically to produce the best chromatography for sample introduction into high resolution capillary columns.

The CIS 4 provides unsurpassed temperature control and sample transfer by using patented heating/cooling technology and an optimized 2 mm inner diameter liner. The CIS line of inlets from GERSTEL are the only inlets that can be cryostatically cooled.

If you are using capillary columns, you should be using an inlet design to achieve the best chromatographic performance instead of hot split/splitless or an "all-purpose" inlets that have been designed with packed columns in mind.

The CIS 4 is designed for use with Agilent Technologies 7890, 6890 and 6850 gas chromatographs. It can also be retrofitted into these models.


Features & Benefits:

  • Optimized for use with capillary columns - Seven modes of injection
  • Electronic pressure control
  • Eliminates thermal discrimination
  • Reduces decomposition of thermally labile compounds
  • Lowers detection limits
  • Can be used as an extremely efficient cold trap
