ABSTRACT:
A spectrophotometer system including a monochrometer which scans a sample in a sample cell with discrete wavelengths of light, and measures intensity signals of at least two discrete wavelengths of light emitted from the sample. These measured intensity signals are base-line corrected by a computer with respect to reference intensity signals at corresponding wavelengths. The computer also calculates base-line corrected intensity signals for wavelengths of light intermediate said two wavelengths of light from the intensity signals of said two respective discrete wavelengths. All base-line corrected intensity signals are stored for analysis of the sample.
