Model Optic-4 - Multimode Inlet Instruments



The Optic-4 has a range of features and solution that are not found in any other GC inlet. The patented low thermal mass design of the inlet body together with direct resistive heating provide fast linear temperature programming up to 600 °C at rates as high as 60 °C/s.

In addition to standard sampling modes, the programmable inlet can operate effectively as Large Volume Injection, Pyrolysis or Thermal Desorption sample introduction device. With the options for sub-ambient cooling, back-flush, cryogenic trapping and automated liner exchange, OPTIC-4 is the world's most versatile inlet for gas chromatography.

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