Silicone rubbers – standard shape
Silicone sheet samplers were chosen because accurate polymer – water partition coefficients (Kpw) are available for many contaminants and there is a good agreement between hydrodynamic theory and experimental sampling rates for these samplers. The SRs with a standard shape are often used in marine environment as is described in the Guidelines for passive sampling of hydrophobic contaminants in water using silicone rubber samplers, Guidelines No. 52, Foppe Smedes, Kees Booij, ICES Techniques in Marine Environmental Sciences, 2012.
The SRs were often used in special sampler holders where usually six sheets are fitted on two neighbouring mounting stems of the holder and are kept in place by a fixing rod without protecting mesh. A standard shape of the sheet is 90 x 55 mm with two 5.5 mm diameter mounting holes (center-to-center distance of 33 mm and center-to-top rim of 30 mm). The active area of one sheet is Approximately 100 cm2. A material is a experienced and tested thin highly-permeable PDMS membrane SSP-M823.
The price of one sheet is without spiking of PRC (performance reference compounds). However, inner standard PRCs are used for proper quantification. A price with PRCs depended on more factors and amount salles are possible that is why a price will be set individually.
