Automated Thermal Desorption Tube Spiking of Volatile Organic Compounds (VOCS) Using GERSTEL Dynamic Headspace Sampler
The spiking of standards (internal standards, surrogates and recovery standards) onto Thermal Desorption Tubes is done widely in laboratories which do environmental & occupational exposure testing.
There are currently two main approaches:
- Spiking with gas standards (manual or automated)
- Manual tube spiking with liquid solutions directly onto the sorbent
Spiking with gas standards is relatively easy to automate using valves and mass flow controllers but, requires a gas standards generator or the purchasing of standards in canisters.
