OPTIC-5 Multipurpose Inlet for Gas Chromatography

  1. Home
  2. Versions of OPTIC-5
We are thrilled to announce the upcoming release of OPTIC-5, available from October 2025. OPTIC-5 represents a groundbreaking advancement in GC Inlet technology, designed to deliver extreme performance. With cutting-edge features and innovative design, OPTIC-5 is set to revolutionize the way a sample is introduced onto a GC column. Stay tuned for more updates as we prepare to unveil the next generation of OPTIC Inlet systems.


OPTIC is a highly advanced Gas Chromatograph inlet system with sophisticated temperature and gas flow control that can be used for the most demanding Gas Chromatograph analyses. The OPTIC GC inlet has a long history starting from 1992. The current version OPTIC-5 can be used for hot injections, cold injections, large volume, on-column injections, in liner derivatization, thermal desorption, pyrolysis and more. There are 3 main versions available, all versions can be added with advanced options.

  • More information
All versions can be supplied with options like: Cold Trap with Silent valve, Inlet backflush, Inlet cooling with LN2, CO2 or Peltier, Automatic Liner Exchanger, PAL3 System.

The patented design of the injector body helps to have the best transfer of the compounds from the inlet onto the analytical column. This can be seen both for volatile and non-volatile compounds.
OPTIC-5 GC Inlet can cool and heat very fast because of the low thermal mass. The GC inlet system can work from cryogenic temperatures (-150°C) up to very high temperatures (1000°C for the Pyro version) with a ramp rate up till 100°C/sec.
Depending on solvent type, liner type and injection speed it is possible to inject from 0.1µl till 500µl in the OPTIC inlet.
With the optional inlet peltier cooler it is possible to cool faster and reach initial temperatures of +7°C.

OPTIC-5 Multi Mode Inlet is designed to be compatible with most popular makes and models of GC and GC-MS instruments.

OPTIC systems consists of the injector, the control unit and the dedicated control software - OPTIControl. The standard supplied OPTIControl graphically displays all the system parameters in a real time mode and gives a possibility to save the run-time data for every injection.


OPTIC-5 is available from October 2025.
More information will come soon.
