Unique
sampling capabilities include custom designed and manufactured samplers
for carbonyl compounds, whole air samples (bags or canisters), and sorbent
cartridges.
- Custom
designed and manufactured samplers for carbonyl compounds that can
collect up to six samples unattended.
- Bag/canister
samplers that can collect up to 24 samples in a series with less than
one second of sample loss in switching.
- Custom
designed and manufactured canister samplers that can collect up to
seven samples (six plus one co-located) or up to three samples in
series or simultaneously with no operator intervention.
- Stainless
steel canisters for volatile organic compounds, including new StabilizerÔ
canisters.
- Tenax
cartridge sampling for semi-volatile organic compounds (C8-C20).
- High and
medium volume organic semi-volatile compound sampling and particulate-matter
sampling (filter and PUF).
- Four channel,
fine particulate/PUF samplers equipped with PM 2.5 cut-off
inlet.
- Aircraft
canister and carbonyl samplers.
- DRI designed
dilution tunnel, suitable for source sampling.
The
Organic Analytical Laboratory maintains all of its equipment according
to strict quality assurance standards.
Quality control procedures define schedules for periodic calibration and
performance t esting including blank and replicate analyses. Pre-defined
tolerances have been established for each piece of equipment, and specific
actions are mandated if tolerances are exceeded during performance tests.
