Most Powerful Multimode Inlet for GC and GCMS  

Shimadzu (Germany) introduces the new OPTIC-4 injector, the 4th generation of the highly successful OPTIC multimode injection system from Atas GL, Eindoven, Netherlands. This versatile tool increases application range and detection limits of the Shimadzu GC and GCMS series.

In addition to the standard sampling modes, the programmable OP-TIC-4 can be operated as Large Volume injector, Pyrolysis or Ther-mal Desorption injection system. DMI (Difficult Matrix Introduction) is also possible by injecting µ-vials filled with sample (solid or highly matrix-loaded) into the OPTIC-4 liner, allowing direct analysis of the compounds in the sample.

The patented low thermal mass design together with direct resistive heating provides a linear temperature range up to 600 °C at rates as high as 60 °C/sec, opening the possibility to apply the OPTIC-4 for a wide range of applications. Combined with the AOC-5000 Plus auto sampler, fully automated sample injection can be utilised using an automatic liner exchanger (LINEX). The variety of different liners supports the wide range of applications using the OPTIC-4.

Using the OPTIC-4 injector as a cold injection system, compounds which usually degrade in hot injectors; for example thermal labile pesticides, can be analysed without any difficulty. Precise and reproducible results can therefore be obtained for low boiling point compounds. The OPTIC-4 temperature range is +10 °C above RT to 600 °C (alternatively -180 °C or -50 °C to 600 °C with the injector cooling option using direct LN2 or CO2 cooling, respectively). The unique solvent monitor enables easy method development for Large Volume injections, which improves detection limits and can be used in all application areas with a need for high sensitivity.
