About OPTIC MultiMode Inlet for any Gas Chromatograph

OPTIC is a highly advanced Gas Chromatograph multi mode inlet system with sophisticated temperature and gas flow control that can be used for the most demanding GC analyses. The OPTIC has a long history starting from 1992. The current version OPTIC-4 can be used for hot injections, cold injections, large volume, on-column injections, in liner derivatisation, thermal desorbtion, pyrolysis and more.
Starting from Evolution Workstation software version 4.5.1 it is even possible to control a Deans’ Switch or flow modulator with the OPTIC Multi-Mode Inlet.

Increase capacity of your GC system with MultiMode OPTIC!

OPTIC-4 Multi Mode Inlet can cool very fast because of the low thermal mass. The GC inlet system can work from cryogenic temperatures (-150°C) up to very high temperatures (600°C) with a ramp rate up till 60°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-4 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 - Evolution Workstation. The standard supplied Evolution Workstation graphically displays all the system parameters in a real time mode and gives a possibility to save the run-time data for every injection.
The Evolution Workstation can be integrated into Master lab, MassHunter, Chemstation, Clarity, Analyst, EZChrom and Xcalibur by the Chronos master software. The PAL system can be controlled direct from Chronos as well.

OPTIC-4 can be delivered in different configurations, with or without cryotrap, auxiliary gas control for back flush or flow modulation, different versions of the inlet body and even custom build OPTIC's are possible.
A special version for thermal desorption is available, this version is compatible with 1/4 inch x 3.5 inch TD tubes.
There are many applications, publications and posters available.
