An infrared analyzer for detection of mineral oil in water has been developed. Special techniques are used in the designing of the instrument, including liquid core waveguide infrared absorption techique, spectral retina technique, source stabilization technique,high precision source modulation technique,and simple, stable and safe sample introduction technique. The instrument has excellent analytical performance: high stability and precision (RSD<1%),high sensitivity (10 times highter than conventional instruments),wide linear dynamic range (0.10～120.00mg/L),low detection limit (0.027mg/L,oil/extractant)and good linearity. The correlative coefficient R2 is >0.999. It can be widely used for quantitative determination of mineral oil in water, animal and vegetable oil in water, oils in soil , oils in oil smoke as well as residual oils on surfaces of semiconductor devices and other industrial products.
