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.
