Abstract: Spectral retina is a quite new technique in spectroscopy. It has been employed for the first time to an IRoil content analyzer. The instrument using this technique has a series of merits: compact, pegged (without moving parts), simple in operation as well as high speed in measurement. In this paper, a Model 450 oil content analyzer based on spectral retina technique is described in details. The results show that the instrument has such excellent analytical performance as a good stability, a high precision (RSD< 1 %), a low detection limits 0.027 mg/L(oil/extractive reagent), a high sensitivity (a faster of 10 improvement compared), and a wide linear ranges (103).

Key words: Spectral retina technique, Infra-red, Oil content analyzer
