4th generation of OPTIC multimode Inlet for gas chromatography

OPTIC is a highly advanced gas chromatograph multimode inlet system with sophisticated temperature and gas flow control that can be used for the most demanding GC analyses. OPTIC has a long history starting from 1992. The current version, OPTIC-4, can be used for hot, cold, large volume and on-column injections, in-liner derivatisation, thermal desorption, pyrolysis and much more. Dirty, solid or liquid samples can be analyzed using Difficult Matrix Introduction (DMI) technique. With DMI, a sample is introduced into a small micro-vial placed inside an OPTIC liner. In addition, the OPTIC controller is capable of a Deans’ switch or flow modulator control. An optional cryogenic trap with the fast heating ramp rate is also a valuable feature. The patented low thermal mass design of the inlet body together with direct resistive heating provides fast linear temperature programming up to 600 °C at rates as high as 60 °C/sec.

With the OPTIC-4, an analyst can introduce into GC a wide range of samples including the ones containing matrix or thermally labile compounds. The samples can also be water based or solids. Automated solvent venting procedure based on the standard solvent sensor in the split line makes the large volume injections as easy as the industry standard split or splitless.
