1.0.1 OPTIC Liners

This liner is normally used for the hot and cold splitless injections of the sample volumes below 3 µl. The narrow, 1 mm internal diameter of the liner ensures fast sample transfer  to the column under the splitless conditions. We also advise this liner for SPME technique. (not SPME Arrow)

When silanized, this liner becomes very inert. It is deactivated using a proprietary deactivation process. The maximum working temperature for the silanised liners is 320°C. More about our deactivation.

The sintered glass liner is suitable for the large volume injections of high molecular weight compounds. The capacity of the liner is a bit lower than that of a packed liner (approx. 50 µl, depending on a solvent used). To maximize the sample capacity, the liner should be used in combination with a syringe fitted with a dome tipped side-hole needle.

When silanized, this liner becomes very inert. It is deactivated using a proprietary deactivation process. The maximum working temperature for the silanised liners is 320°C. More about our deactivation.

The DMI liner is used for Difficult Matrix Introduction (DMI) in combination with 2414-1015 (Glass Needle Guide) and 2406-1010 (DMI Sample Insert). The liner has 2 or 3 indentations to hold a sample insert. The DMI technique extends the OPTIC capability to the analysis of dirty liquid samples containing non-volatiles and/or solid-like suspended matrix.
Raw sample or roughly filtered extract is placed into a sample insert (2406-1010) and is inserted into the liner. The needle guide 2414-1015 is used to ensure an accurate sample injection.

When silanized, this liner becomes very inert. It is deactivated using a proprietary deactivation process. The maximum working temperature for the silanised liners is 320°C. More about our deactivation.
