Abstract: Raman spectroscopic analyzer including: a beam-casting unit 3 for receiving a light beam generated by a light source and for converging the light beam on a predetermined position in a perpendicular direction to the longitudinal direction of a measurement chamber through which a liquid sample is passed; and a light-receiving unit placed at a distance in the longitudinal direction from the predetermined position, for receiving scattered light emitted from the fluid sample. Among the scattered light which enters the light-receiving unit, the portion which enters this unit after being reflected by the inner wall surface opposite to this unit is eliminated, so that the amount of noise in the Raman spectroscopic measurement is considerably reduced.

Abstract: Provided is a gas absorption spectroscopic system and gas absorption spectroscopic method capable of accurately measuring the concentration or other properties of gas even in high-speed measurements. Laser light with a varying wavelength is cast into target gas. A spectrum profile representing a change in the intensity of the laser light transmitted through the target gas with respect to wavelength is determined. For this spectrum profile, polynomial approximation is performed at each wavelength point within a predetermined wavelength width, using an approximate polynomial. Based on the coefficients of the terms in the approximate polynomial at each point, an nth order derivative curve, where n is an integer of zero or larger, of the spectrum profile is created. A physical quantity of the target gas is determined based on the thus created nth order derivative curve.
