Performance optimization of a passive sampler for monitoring hydrophobic organic pollutants in water
Journal article, 2005
The performance of an integrative passive sampler that consists of a C18 Empore disk sorbent receiving phase fitted with low d. polyethylene membrane was optimized for the measurement of time-weighted av. concns. of hydrophobic micropollutants in water. A substantial improvement of sampling characteristics including the rate of sampling and the sampling precision was achieved by decreasing the internal sampler resistance to mass transfer of hydrophobic org. chems. This was achieved by adding a small vol. of n-octanol, a solvent with high permeability (soly. * diffusivity) for target analytes, to the interstial space between the receiving sorbent phase and the polyethylene diffusion-limiting membrane.
