METHOD AND APPARATUS FOR DETECTING CHEMICAL CONTAMINATION |
摘要 |
The method detects the presence of poly-chlorinated biphenyls on a surface, by the use of UV fluorescence spectroscopy in the back-emitting mode. The apparatus comprises a source of UV radiation. Exposure means are provided fo r conveying UV radiation from the source to the surface. Collecting means collect radiation back-emitted from the surface. A filter filters the collected radiation, and a spectrometer analyses the filtered collected radiation. The filter allows radiation having a wavelength within the range of from 320 nm to 360 nm to pass to the spectrometer.
