Each Chemcatcher® deployment requires the following
1 A Chemcatcher® deployment unit
2 This must must be fitted with 3 detectors (i.e. the housing plus disk and membrane). You will also need a field blank detector per site and 1 x fabrication blank detector per assessment. Therefore a total of 5 detector units are required. (However, if a number of sites are being monitored at the same time, one set of blanks (i.e. 1 x fabrication blank and 1 x field blank) is sufficient.
Chemcatcher® can be adapted to detect a wide range of substances – from trace metals, PAHs, PCBs and pesticides to pharmaceutical and personal care residues – depending on the materials chosen for the receiving phase and the membrane selected.
Use the tables below to determine the most appropriate deployment unit and the correct disk and housing for the pollutant(s) being detected.
1. Choose deployment unit
| Deployment Unit | Comments |
|---|---|
| Stainless Steel Cage | Recommended option, in terms of best stability, particularly in flashy rivers Suitable for all parameters except metals Can accommodate up to six disk detector disks, meaning two studies can be carried out simultaneously |
| Plastic Plate | Suitable all parameters, including metals |
| Mesh Bags | Least recommended option in terms of stability Suitable for all parameters, including metals |
2. Select the correct housing, disk and membrane for your application
Table 2a Requirements for Detecting Mollusc Pesticides or Pharmaceuticals/Personal Care Products/Illicit Drugs
| I want to detect | System Required | Housing Size and Price | Disk & Membrane Required |
|---|---|---|---|
| Mollusc Pesticides | Metaldehyde Chemcatcher® | 52 mm housing | HLB-L receiving disk PES membrane |
| Pharmaceuticals /Personal Care Products/illicit drugs | Polar Pharma Chemcatcher® | 52 mm housing | HLB-L receiving disk PES membrane |
Table 2b Requirements for Detecting Metals (e.g. PD, Cd, Zn, Cu), Radionuclides, Acid Herbicides/Pesticides, Perfluorooctane Sulfonic Acid/Perfluorooctanoic Acid (PFOS/PFOA), Polycyclic Aromatic Hydrocarbons (PAH) and Polychlorinated Biphenyls (PCBs/PAHs) or Organometallics
(e.g. Buytlins)
| I want to detect | System Required | Housing Size | Disk & Membrane Required |
|---|---|---|---|
| Metals (eg PD, Cd, Zn, Cu) | Metal Chemcatcher® | 47 mm housing | Metal receiving disk PES membrane |
| Radionuclides | Radionuclide Chemcatcher® | 47 mm housing | RAD receiving disk PES membrane |
| Acid Herbicides/ Pesticides | Polar AP Chemcatcher® | 47 mm housing | Anion SR receiving disk PES membrane |
| PFOS/PFOA | Perfluoralkyl Chemcatcher® | 47 mm housing | Anion SR receiving disk PES membrane |
| PCBs/PAHs | Non-Polar Chemcatcher® | 47 mm housing | C18 receiving disk LDPE membrane |
| Organometallics (e.g. buytlins) | Organometallics | 47 mm housing | C18 receiving disk PES membrane |
