Help with selecting the wanted OPTIC-4 version:
First main selection is the liner type: standard type (OD: 5mm x L: 81mm) or ¼ inch type (OD: ¼ inch x L: 3.5 inch).
Most common version of the OPTIC-4 is the standard type, this type has also more possibilities. The ¼ inch version is mainly for thermal desorption applications where the industry standard ¼ inch x 3.5 inch thermal desorption tubes are used. If you are not stuck to the ¼ inch thermal desorption tubes, we advise to select one of the standard versions of the OPTIC-4. The standard version is also very good for thermal desorption and many other techniques.

Next to select is a version with or without cryotrap. A cryotrap option helps to improve peak shape and detection level. The compounds coming from the inlet are refocused on the first part of the column and after trapping the cryotrap is heated in a very fast wat resulting in sharp peaks. Most of the times a trap is used in combination with pyrolysis and thermal desorption techniques.
