摘要
An absorption spectroscopic system is provided with a detector that detects an intensity of light transmitted through a gas, a total pressure sensor that measures a total pressure of the gas, an interference gas partial pressure-absorbance relationship storage unit that stores interference gas partial pressure-absorbance relationship data, an interference gas partial pressure estimation unit that estimates the partial pressure of the interference gas based on the total pressure measured by the total pressure sensor, an interference gas absorbance conversion unit that converts an estimated partial pressure of the interference gas estimated by the interference gas partial pressure estimation unit into an absorbance of the interference gas based on the interference gas partial pressure-absorbance relationship data, and a target gas absorbance calculation unit that calculates an absorbance of the target gas based on output values from the detector and on the absorbance of the interference gas.
