PAL Applications for Gas Chromatography
|
|
Chromtech TDAS Applications
TDAS stands for Thermal Desorption Autosampler. Developed by Chromtech, GmbH. as an accessory for the CTC Combi PAL.

Chromtech SMM Applications
SMM or Single Magnet Mixer Developed by Chromtech, GmbH. as an accessory for the CTC Combi PAL.
The most beneficial application of the Single Magnet Mixer is SPME. SMM is gentle to the fiber and needle increasing fiber lifetime.
The liquid is mixed by a small magnet inside the vial and creates a vortex at high speeds up to 750rpm, 1500rpm optional. Samples can be heated
up to 150C or cooled with the peltier option.

SPDE Applications
SPDE features full automation for dynamic sample extraction, desorption and analysis using the CTC Combi PAL. Most of our customers use SPDE for
food and flavor research, forensic analysis or environmental applications.
A gas-tight 2.5mL syringe is equipped with a special needle that is coated on the inside with an extraction phase. During the adsorption process A liquid
or headspace sample is drawn up into a 2.5mL syringe, thereby adsorbing analytes onto
the stationary phase.
Then, the autosampler moves the syringe over to the hot GC inlet, and the analytes are desorbed.
