FLP Oil-in-Water Analyzer

Operating Principle

The FLP Oil-in-Water Analyzer utilizes a 255 nm deep ultraviolet (DUV) LED as its excitation light source. A small portion of this light is captured by a reference detector to compensate for fluctuations in the light source, while the majority excites the water sample. The resulting 365 nm ultraviolet fluorescence is detected and analyzed to determine oil-in-water concentration.
