LINEX is a new revolutionary approach, allowing you to perform direct (in-injector) analysis of different samples with little, if any, sample preparation. The automated GC liner exchange is a technique developed by ATAS GL Science.

LINEX Advanced Features 

•  Can be installed on an Agilent or other type of GC
•  Little, if any, sample preparation is required
•  Can be automated by CTC Analytics PAL Combi-xt autosampler
•  Based on proven OPTIC injection technology
•  Uses standard wide bore (3.4 mm ID) OPTIC liners
•  Sample tray for 28 or 98 samples (option)
•  Uses standard 11 mm septa or Merlin Microseal™
•  Retains true injector septum purge
•  Liquid injection can also be done while injector head is closed
•  No liner transport adapter is required
•  Low consumable costs

LINEX-DMI

LINEX-DMI is a system designed to be used for the GC analysis of dirty samples. It can be quickly, in a matter of minutes, mounted on any standard OPTIC injector. Standard wide-bore DMI liners can be handled by LINEX either in manual or automated mode. In the automated mode liners are transported between the sample tray and inlet by Combi PAL sampling robot equipped with a pneumatic gripping arm.

The newly developed LINEX-DMI is a most promising automated system for the analysis of samples containing difficult non-volatile or solid-like suspended matrix using the ATAS GL Science Difficult Matrix Introduction (DMI) technique.

LINEX-TD 

Originally the automated GC liner exchange has been successfully used in ATAS GL Direct Thermal Desorption (DTD) unit. LINEX-TD is a new version of DTD, allowing you direct (in-injector) extraction of volatiles and semi-volatiles from various matrices including the solid state samples.

LINEX-TD can be quickly, in a matter of minutes, mounted on any standard OPTIC inlet. Wide-bore OPTIC liners can be handled by LINEX either in manual or automated mode. In the automated mode liners are transported between the sample tray and inlet by PAL sampling robot equipped with a pneumatic gripping arm.

With LINEX-TD, the multi-sample analysis sequence works in a simple way: head of the inlet is automatically opened and a liner containing sample is introduced into the inlet. The head is closed and the liner is purged with carrier gas. Next, the inlet is heated and volatile and semi-volatile compounds are extracted and transferred onto the column. At the end of the analysis the liner is moved back to the tray and the cycle is repeated.
