The fritted liner is very useful for the solid thermal desorption, hot and cold split/splitless injections, LVI injections with the maximum injection volume up to 3 µl (the use of some packing material or a glass/quartz wool is advised in this case). A frit is placed at 15 mm from the liner bottom.

When silanized, the OPTIC fritted 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.

Carbosieve S is a large surface area carbon molecular sieve which is ideal for trapping the smallest organics. While it has a higher affinity for water than most other resins, its small pore size provides the best trapping ability for the volatile organics.

Properties:

• Chemical Structure or Name: carbon molecular sieve

• Temperature Limit: 400 degrees C

• Surface Area: 820 square meters per gram

• Average Pore Size; 15-40 angstrom

• Affinity for Water: moderate

• Mesh size: 60/80 mesh
