The Thermal Desorber TD 3.5+ is a flexible automated solution for thermal desorption and thermal extraction. The TD 3.5+ fits on top of any modern GC without the need for additional bench space and it is perfectly suited for materiel emission analysis and for thermal desorption of sorbent tubes used to sample whole air. The TD 3.5+ handles standard 3.5” tubes, as prescribed in several standard methods, in addition to GERSTEL plus tubes, which hold up to 20% more sorbent for enhanced break-through volume, improved recovery as well as improved limits of detection. The TD 3.5+ incorporates the latest advances in thermal desorption technology. Intelligently designed and based on a “Liner-in-Liner” concept, it has no valves, transfer lines or cold spots. The TD 3.5+ is connected directly to the GERSTEL Cooled Injection System (CIS), which serves both as a 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 TD 3.5+ can be operated in single split, dual split or true splitless mode enabling it to cover the widest range of concentrations, protect the column from water and contamination and to achieve the lowest possible limits of detection. The TD 3.5+ low-flow split pneumatics provide improved flexibility and performance. For extreme sensitivity, the multi-desorption mode can be selected in MAESTRO software.
Supports multiple techniques:
The TD 3.5+ supports manual operation and it can be removed in seconds to enable direct liquid sample introduction into the GERSTEL Cooled Injection System (CIS), a PTV-type universal GC inlet.
When configured with the GERSTEL MultiPurpose Sampler (MPS robotic), up to 40 samples are stored per TD 3.5+ tray in individually sealed sample positions. The system can easily be scaled up by using up to three TD 3.5+ trays per tray holder. The number of tray holders depends on size and configuration of the MPS robotic.
