Silicone Rubbers – description

Silicone rubbers are well-established passive samplers of nonpolar compounds.
This is what you need:

  1. Sampler housing
    We recommend the standard housing or the housing for shallow waters that are also used for SPMDs.  You can also use your own housing design.
  2. Silicone rubber sheets
    • Our “Silicone rubbers strips – shaped like SPMD” are easily mounted in the housings for SPMDs.
    • Our “Silicone rubbers – standard shape” fit the housing that is listed in the ICES guidelines (90×55 mm with 5.5 mm mounting holes that are 33 mm apart)
    • We can manufacture sheets of any other shape that fits your specific housing design, using laser cutting technology.
    • We recommend the following number of samplers per study.
      – exposed samplers: number of sites times replicates per site
      – field/trip control samplers: number of sites times 0.2
      – fabrication control samplers (for determining initial PRC amounts and blank levels): 4
  3. PRC spiking
    • We can reproducibly spike samplers with PRC, but you can also purchase samplers without PRCs.
    • We recommend the following standard set of PRCs:
      – PCB 1, 2, 14, 30, 50, 104, 145, 204
      – benzo[b]fluoranthene-d12
    • We recommend a spiking level of approximately 100 ng per sampler for PCBs-type PRCs and 300 ng per sampler for deuterated PAHs. Spiking levels can be made higher or lower, depending on your preference.
    • The standard set of PRCs can be extended for improved accuracy or modified if needed. Please refer to the options on separate page.
    • Check that selected PRCs are not used as analytical internal standards in your laboratory
