Thermal Desorption Unit – TDU 2
The new GERSTEL Thermal Desorption Unit (TDU 2) is the heart of the most flexible and powerful sample introduction platform available for your GC/MS.
The TDU 2 is a fourth generation Thermal Desorption instrument from GERSTEL, building on more than 20 years of experience. The TDU 2 offers the highest performance, new low split pneumatics for improved LODs, built-in alignment support for easy liner change, and automation performed by the MPS robotic offering high precision delivery of samples, Barcode reading capability and up to 240 TDU tube sample capacity in standard configurations.
The TDU 2 enables ultra-trace analysis of a wide range of samples. Mounted directly on top of the CIS inlet without the need for a transfer line, the TDU provides a completely inert sample path for best possible analyte recovery.
The GERSTEL MultiPurpose Sampler (MPS/MPS robotic) is extremely versatile. The system performs automated spiking of adsorbent tubes with liquid standards as well as multiple sample introduction techniques such as Liquid, HS, SPME plus the following seven:
- Thermal Desorption of sorbent packed tubes
- Direct Thermal desorption/extraction of solids
- Thermal Extraction of liquids in μ-vials
- Dynamic Headspace – DHS and DHS Large (1 L)
- Hot injection and trapping (HIT) for HS
- Stir Bar Sorptive Extraction (SBSE)
- Pyrolysis using the GERSTEL PYRO
It is extremely easy to add – or switch between – sample introduction techniques. All techniques are fully controlled by GERSTEL’s powerful, yet easy to use MAESTRO software. The complete integration of MAESTRO into Agilent’s GC/MS software allows set up through dropdown menus and combined storage and reporting of all method parameters.
