Concentrate and Store Analytes from Water; Sample Indoor Air - The SPME portable field sampler is an efficient and economical way of extracting and transporting volatile and semivolatile compounds from field samples. Extracted compounds storage losses for pesticides extracted and stored using a portable field sampler were significantly lower than losses from stored whole water samples. The sampler can be reused 50-100 times, and is disposed of when the fiber is no longer usable.
The portable field sampler also efficiently detects organic compounds in air. In our studies, the sampler allowed us to monitor typical HPLC and GC solvents at ppb levels in laboratory air. Four fibers are available: a polydimethylsiloxane
(PDMS)/Carboxen fiber for trace levels of volatiles, a general purpose PDMS fiber, a PDMS/DVB fiber for semi-volatiles and larger volatiles, and a Carbowax/DVB fiber for polar semivolatiles.
