        Pyrolysis modes with the OPTIC 3 injector
The OPTIC pyrolysis solution has several modes:

Single Shot
With this method or mode the sample is heated after introduction with a fast speed to the pyrolysis temperature. Only one temperature step is used.

Multistep programmed pyrolysis
Analytical runs may be programmed for up to nine temperature steps per sample.

Sample Cup or Micro Vial
A small glass sample cup is available to introduce a sold or liquid sample.

Evolved Gas Analysis (EGA)
the sample is dropped into the furnace which is at a relatively low temperature (ca. 40-100°C). The furnace is then programmed to a much higher temperature (ca. 600°C). Compounds "evolve" from the sample as the temperature increases. A plot of detector response versus furnace temperature is obtained.

Thermal Desorption (TD)
Thermal desorption is simply a technique for analyzing the constituents evolving from the sample over a given temperature range.

Reactive Pyrolysis
Thermally assisted Hydrolysis and Methylation (THM) can easily be done under Helium conditions.

Cryofocusing
Option-produces sharper peaks for early eluting compounds. A cryotrap mounted in the GC oven cools the first part of the column for refocusing of the compounds. (device is cooled by LN2 or CO2)
