Gas chromatography thermal desorber TDU 2

The worlds most flexible Thermal Desorption Instrument The Thermal Desorption Unit (TDU 2) is a flexible automated solution for thermal desorption and thermal extraction. The TDU 2 fits on top of any modern GC without the need for additional bench space and it is perfectly suited for the analysis of gaseous, liquid and solid samples. The TDU 2 incorporates the latest advances in thermal desorption technology. Intelligently designed and based on a “Liner-in-Liner” concept it has no valves or transfer lines. The TDU 2 is connected directly to the GERSTEL Cooled Injection System (CIS), which serves both as a cryo-focusing trap and as a temperature programmable GC inlet. Active sites are eliminated, reducing the risk of analyte loss, discrimination and memory effects to an absolute minimum. The TDU 2 can be operated in split or true splitless mode enabling it to cover the widest range of concentrations, to protect the column from water and contamination and to achieve the lowest possible detection limits. The TDU 2 low-flow split pneumatics provide improved flexibility and performance. For extreme sensitivity, the multi-desorption mode can be selected in MAESTRO.
