The Chelsea Technologies Group's OIL-Wader and OIL-Wader Pro systems provide surveyors and regulators with real-time in situ measurement of dissolved Polycyclic Aromatic Hydrocarbon (PAH). The OIL-Wader comprises a CTG UviLux fluorometer and a Hawk handheld display and logging unit. CTG’s UviLux fluorometers detect UV fluorescence with industry-leading sensitivity and selectivity and have been optimised for minimal interference from water turbidity.
Data is displayed on the Hawk’s colour touchscreen and logged internally. If required, the Hawk can be programmed to apply a user calibration to the reported values. The Hawk also incorporates a GPS receiver so that all logged data can be position and time stamped.
Examples of detectable compounds include:
- Naphthalene (NDSA)
- Pyrene (PTSA)
