With the GERSTEL DHS option, dynamic headspace can be 100% automated.
The DHS station completely extracts, concentrates and injects VOC and/or SVOCs from liquid or solid samples placed in standard Headspace vials.
The sample is thermostatted and agitated while the headspace is purged with a controlled flow of inert gas, providing controlled and efficient extraction conditions.
The DHS station also holds the replaceable adsorbent- or sorbent filled tube used for analyte concentration.
Sample temperatures can be selected from 10 °C to 200 °C.
The temperature of the adsorbent tube during the DHS process can be varied from 20 °C to 70 °C for optimal trapping of the analytes in question.
Collection and more
Adsorbent tubes used are standard GERSTEL Thermal Desorption Unit TDU tubes filled with Tenax/Carbopack/Carbotrap of your choice. Following analyte concentration, the tube is automatically transferred to the TDU for Thermal Desorption and analyte transfer to the GC.
Tubes are fitted with individual adapters enabling both automated movement and leak-free sealing during the Dynamic Headspace and Thermal Desorption steps and during storage in the autosampler tray.
