Rapid semi-continuous calibration and field test of membrane-enclosed silicone collector as passive water sampler

Overview of the Chemcatcher® for the passive sampling of various pollutants in aquatic environments Part A: Principles, calibration, preparation and analysis of the sampler

“…Inorganic pollutants can be sampled by DGT (Diffusive Gradient in Thin film) or Chemcatcher s [3]. For organic pollutants, several passive sampler designs have been developed: POCIS (Polar Organic Chemical Integrative Sampler), SPMD (Semi-Permeable Membrane Device), MESCO (MembraneEnclosed SorptiveCOating), Chemcatcher s and others [3][4][5][6].…”

Passive Sampling Technologies for the Monitoring of Organic and Inorganic Contaminants in Seawater

“…These single-phase partition-type samplers have high uptake rates, similar to those of the SPMD, for many nonpolar priority pollutants. Other samplers for hydrophobic organic compounds (logK OW > 3) include the nonpolar version of the Chemcatcher (consisting of an n-octanol-soaked C18-3 M Empore™ disk overlaid by a thin LDPE membrane) (Greenwood et al 2007b) and various configurations of the MESCO sampler (Paschke et al 2006). Polar samplers consist of an adsorption phase overlaid by a thin polar diffusion-limiting membrane.…”

Monitoring of Aquatic Environments Using Passive Samplers

“…A new MESCO that uses a silicone collector instead of a stir bar coated with poly(dimethylsiloxane) (PDMS) has been reported by Paschke et al [30]. The sampler consists of a lay flat membrane strip, 15 cm x 3 cm with 100 μm thickness.…”
