Auto-sampler for gas chromatography
Markes International Limited

ULTRA 2 adds to Markes UNITY 2 TD platform to provide automatic desorption of up to 100 industry standard (3.5-inch) or DAAMS (Depot Area Air Management System as used in some chemical agent test facilities) (4.5-inch) tubes with or without RFID tags.

The peerless analytical performance and key sample protection features of UNITY 2 features are maintained on series 2 ULTRA-UNITY systems.

Series 2 ULTRA autosamplers herald a revolution in automated thermal desorption. Every ULTRA 2 offers the option to read information from RFID tags attached to sorbent tubes and to automatically input this information into the sequence table.

At the end of each analysis, ULTRA 2 can also write to the tube tag e.g. to increment the number of thermal cycles, input any high back-pressure anomalies, change the tube status and clear sample-specific data from the tag ready for the next field monitoring operation.

Markes TubeTAG technology allows error-free tracking of samples from field to laboratory & within a laboratory (transit tagging) and logging of key tube-specific data such as type & date of sorbent packing. In combination with a series 2 ULTRA-UNITY system TubeTAG further enables:

Automatic logging of the history of a tube throughout its life: Number of thermal cycles, back-pressure anomalies, number of leak test failures, etc.

Automatic input of sample-specific information to the ULTRA TD automation sequence table: Tube number, sampled volume, diffusive sampling time, date of sampling, etc.
