Thermal Desorber Offers Flexibility for Material Emissions, Flavour and Air Analysis

Designed for material emissions-, flavour- and air analysis, the Thermal Desorber TD 3.5+ fits on top of any modern GC without the need for additional bench space and it handles standard 3.5” tubes, as prescribed in several standard methods as well as Gerstel plus tubes with up to 20% more sorbent for enhanced break-through volume and improved recovery and limits of detection.

The TD 3.5+ incorporates the latest advances in thermal desorption technology. The liner-in-liner design without transfer line reduces analyte loss and memory effects ensuring accurate analysis results. The TD 3.5+ 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 TD 3.5+ can be operated in single split, dual split or splitless mode enabling it to cover the widest range of concentrations, to protect the column from water and contamination, and to reach the lowest possible limits of detection. For extreme sensitivity, multi-desorption mode is simply selected in the method.

The Gerstel MultiPurpose Sampler (MPS robotic) holds up to 120 samples per tray holder, in individually sealed sample positions. The number of tray holders that can be mounted depends on the size and configuration of the sampler. The TD 3.5+ in combination with DHS 3.5+ performs dynamic headspace analysis of samples placed in sample containers ranging from 10 mL to 1 L volume.

The MAESTRO software combined with Agilent Technologies® MassHunter or ChemStation controls the complete process from DHS to thermal desorption to GC/MS analysis with one integrated method and one sequence table ensuring efficient and error-free operation. Samples can be analysed using one or more methods and priority sample inserted as needed.
