TDU/TDU 2 - Thermal Desorption Unit

The GERSTEL Thermal Desorption Unit (TDU) was initially developed to be a dedicated instrument for use with GERSTEL Twister stir bars, but due to continued system development, it now adds 5 additional sample introduction techniques for GC and GC/MS analysis. The TDU is used with the GERSTEL Cooled Injection System (CIS) on a GC or GC/MS system to enable ultra-trace analysis of a wide range of samples. The TDU mounts directly onto the CIS, eliminating the need for a transfer line and this prevents analytes from contacting active sites and thus provides a completely inert sample path.
