Tubes and samplers

Carbon tubes for sampling of solvents
Diffusion samplers 3M 3500 for solvents (Menu A1-A6)
Diffusion samplers 3M 3520 for solvents (Menu A1+vinylchloride
XAD-2 tubes
OVS tubes for sampling of PCB

Carbon tubes and diffusion samplers can be ordered from this website.

For sampling with diffusion samplers, a field blank is recommended.
Analyses are carried out in collaboration with a subcontractor.
Other air analyses are available. Please contact the laboratory for information.
