CHROMATOGRAM DATA PROCESSING DEVICE AND PROCESSING METHOD |
摘要 |
Regarding a chromatogram data processing device configured to process three-dimensional chromatogram data collected on a target sample in which dimensions are made up of time, wavelength, and absorbance, and the chromatogram data processing device includes a differential spectrum generating means configured to generate a differential spectrum that represents a change in a wavelength differential coefficient, which is a differential coefficient in a wavelength direction in a predetermined wavelength range, based on the three-dimensional chromatogram data, with respect to an absorbance spectrum representing a relation of the wavelength and the absorbance at each time in an entire temporal range or a predetermined temporal range, and a determination means configured to determine whether or not one or plural other components are included in a peak of a target component, based on a temporal change in a waveform of the differential spectrum, so that the determination on whether or not a target sample includes impurities can be performed with high accuracy without the requirement of complicated computation processing. |

1. A chromatogram data processing device configured to process three-dimensional chromatogram data collected on a target sample in which dimensions are made up of time, wavelength, and absorbance, comprising:
a differential spectrum generating means configured to generate a differential spectrum that represents a change in a wavelength differential coefficient, which is a differential coefficient in a wavelength direction in a predetermined wavelength range, based on the three-dimensional chromatogram data, with respect to an absorbance spectrum representing a relation of the wavelength and the absorbance at each time in an entire temporal range or a predetermined temporal range; and a determination means configured to determine whether or not one or plural other components are included in a peak of a target component, based on a temporal change in a waveform of the differential spectrum. |
