Calculation of the Optical Path Optimal Length of the Flow Cell of Spectrometric System for the Research of Gasolines

Abstract

In this paper, the calculation of the optical path optimal length of the flow cell for commercial gasoline based on the spectral absorption coefficients of gasoline and its components in the near infrared region is suggested. A mathematical model and a criterion for estimating the optical path length of the cell are presented. The calculations determined the working range of the coefficients of transmission and error measurements.
