Abstract
A chromatography quality control device includes a measurement data acquirer that acquires measurement data obtained as a result of measurement in a chromatograph and stores the measurement data in a storage device, a chromatogram factorizer that retrieves the measurement data from the storage device, dimensionally compresses a chromatogram obtained from the measurement data by factorization and stores component data, the component data obtained by the factorization, in the storage device, and a component data outputter that retrieves the component data from the storage device and outputs the component data to a display device.
Claims6
A chromatography quality control device comprising:
- a storage device, a processor and a display,
- wherein:
- the storage device is configured to store measurement data obtained as a result of a chromatographic measurement, the measurement data being three-dimensional data having a retention-time direction, a spectral direction, and an intensity as elements, and
- the processor is configured to:
- retrieve the measurement data from the storage device,
- dimensionally compress the measurement data in a spectral direction by factorization to generate component data including a first main component data piece and an n-th main component data piece, and
- output a graph to the display, the graph having a first axis representing an intensity of the first main component data piece and a second axis representing an intensity of the n-th main component data piece.
