Uv Meter Pah / Oil
PHOTOMETRIC ANALYSER FOR POLYCYCLIC AROMATIC HYDROCARBONS/ MINERAL OILS
The analyser is based on the fluorescence photometric determination of the active species dissolved or suspended in water. The sample is irradiated with a specific wavelength in the UV region. The chemical species in the sample absorb energy from the radiation and release it partially as heat and partially as a new radiation in the visible field. The intensity of the emitted radiation is proportional to the concentration of the molecules to be measured. The instrument is particularly recommended for the determination of aromatic hydrocarbons in aqueous samples.
APPLICATIONS
- Aromatic hydrocarbons in water (including BTEX, PAH, phenol, oil and fuel)
- Ground water
- Cooling water
- Drinking water
- Process water
