SPE-tD™ sorptive extraction cartridges
Markes International’s SPE-tD sorptive extraction cartridges are a simple way of sampling less volatile impurities in aqueous samples – applications that would otherwise require manually intensive extraction or distillation before GC analysis.

SPE-tD cartridges are constructed in the form of a hollow tube, coated inside and out with poly(dimethylsiloxane) (PDMS), and operate on the same physical principles as HiSorb probes. The cartridge is simply placed into the sample and agitated, before being removed, rinsed, and placed into an empty TD tube for analysis.
