Title: Method and apparatus for measuring concentration of butane gas
Inventor: FUKUNAGA HIROSHI
IPC: G01N21/35
Filed: 1987-01-30
Abstract: PURPOSE:To enable highly accurate measurement from a very remote point, by detecting measuring light and reference light with a detector to determine the ratio therebetween. CONSTITUTION:A butane gas used is an n-butane gas or i-butane gas. Light with at least one of wavelengths within the characteristic absorption wavelength band, 1.66-1.80mum, of the butane gas as its center wavelength is used as measuring light, while light with at least one of wavelengths outside the characteristic absorption wavelength band as its center wavelength is used as reference light. Then, light of the measuring wavelength and light of the reference wavelength selected are used and passed through a measuring cell to measure the intensity of the light at respective wavelength. From among the resulting measured values, one or several ratios between the measured values at the measuring wavelength and those at the reference wavelength are determined. Thus, the concentration of the n-butane gas or i-butane gas to be measured can be determined from the ratios thus obtained and a relationship between the absorption rate and the concentration predetermined based on n-butane gas or i-butane gas with the known concentration.
