Spectrophotometer and spectrometric data processing method

Abstract

A spectrophotometer (10) comprises: a measurement spectrum acquisition unit (151) configured to acquire a measurement spectrum obtained by spectrophotometric measurement; a measurement spectrum peak identifying unit (152) configured to identify a measurement peak which is a peak existing in the measurement spectrum; a removal target wavenumber equivalent value acquisition unit (153) configured to acquire, from a database, a removal target wavenumber equivalent value which is a wavenumber equivalent value of a peak attributed to a molecule of a known component whose concentration in a measurement atmosphere fluctuates; and a removal target peak removing unit (154) configured to perform processing of removing, from the measurement spectrum, a measurement peak located at a position corresponding to the removal target wavenumber equivalent value.
