10 reasons to use the GERSTEL Thermal Desorption System 1 2 No valves in flow path; GRAPHPACK fittings 3 Short, heated transfer line; only 15 cm long 4 No cold or hot spots in sample introduction system 5 Multi-level temperature programmed desorption chamber 6 Cooled pre-drying and purging of desorption chamber 7 Reduce sample matrix contribution and improve extraction efficiency 8 The TDS 3 transfer line is 15 cm long and can be heated to 400 ° C. There are no cold spots in the system. These features provide optimum transfer of components and high-boiling materials to the column (see...

Cooled inlet functions as focussing trap; provides split/splitless sample introduction, use of selective adsorbents, and high flow-inert sample transfer. No downtime due to valve failure, contamination or leaks. Optimum analyte transfer with minimal exposure to high transfer line temperatures. Transfer of high boiling compounds with minimal mass discrimination and sample degradation. Transfer only the compounds of interest to the cooled inlet. Reduce analysis time and system contamination. Pre-drying and purging can be used to eliminate water, solvents or oxygen, while still retaining...

The GERSTEL TDS 3 Thermal Desorption System provides you with maximum flexibility Conventional Thermal Desorption Volatile and semi-volatile compounds can be determined by sampling a gas using a wide range of adsorbents. Desorption of the sample can be performed in four different modes using a flexible, software controlled pneumatic system. Direct Thermal Extraction Dynamic headspace of volatile and semi-volatile compounds in solids or gels can be performed directly without sample preparation. Simultaneous Liquid Injection The TDS allows liquid injection to be performed simultaneously in...

Manual thermal desorption system for conventional thermal desorption or direct thermal extraction/dynamic headspace. The system has the option provides complete automated processing of up to 20 samples using multiple analysis methods. The GERSTEL TDS 3PLUS has an integrated Peltier cooling system that eliminates the need for cryogenic

Technical Summary GERSTEL Thermal Desorption Systems Thermal Desorption System Transfer capillary Desorption tubes Conventional thermal desorption systems usually consist of a desorption unit, a cooled trap and a GC inlet. The TDS 3 is a high- performance thermal desorption system that uses the GERSTEL cooled injection system to function as both a cryogenic trap and a GC inlet. Analytes are focussed in the inlet liner, not the column, before being transferred onto the analytical column as a narrow band. The use of the inlet liner as a trap allows much greater flexibility when trapping...

High performance auxiliary modules for even greater versatility GERSTEL Tube Conditioner TC Conditions up to ten GERSTEL thermal This sample preparation system accommodates desorption tubes simultaneously. Tubes larger size samples, separates moisture from are held at a controlled temperature and the matrix, and provides an even higher level are purged with inert gas. Packed and empty TDS tubes. Off-line conditioning system • Conditioned TDS tubes available • Extends useful life of all of tubes • Reduces cost per analysis • Improves detection limits Sample applications Packaging industry •...

Online analysis with the TDS gas streams or large volume headspace. It features automatic sample volume contol and reversed sample desorption flow. Sample taken from rape plants Extracted ion chromtogram. The figure shows the mass traces spiked with a 22 Compound Standard Transfer of Fraction #1 (pre-Benzene) onto the Polar Column Transfer of Fraction #2 (past Benzene) onto the Polar Column

Reliable results with GERSTEL approved consumables subjected to rigoros testing before being approved for use with GERSTEL systems, thus ensuring optimum Stores up to 20 TDS tubes. The automatic sealing system on this interchangeable magazine ensures that tubes are stored safely with an airtight seal. The magazine can be inserted directly into the TDS A. The tubes are then introduced automatically into the TDS 2 for analysis and returned to the magazine when Storage Containers Containers with airtight seal. These have been carefully designed to hold individual TDS tubes during storage or...
