  • Publication number: 20220107294
    Abstract: A sample chromatogram produced by measurement of a mobile phase into which a sample has been injected is acquired by a sample chromatogram acquirer. A background chromatogram produced by measurement of a mobile phase into which a sample is not injected or a mobile phase into which a control sample is injected is acquired by a background chromatogram acquirer. Alignment of a sample chromatogram and a background chromatogram is performed by an alignment processor by causing of baselines of the acquired sample chromatogram and the acquired background chromatogram to coincide with each other. Subtraction processing of subtracting a background chromatogram from a sample chromatogram after alignment is executed by a subtraction processor.

  • Publication number: 20210089952
    Abstract: A model estimator (11) estimates a model function of an analyzing system (20) based on target observation data and reference observation data. For this estimation, the amount of variation between the model of the target system and that of a reference model is estimated from the target observation data and reference observation data. The model function of the target model is estimated after the observation data are corrected based on the estimated amount of variation. A parameter determiner (12) calculates an acquisition function based on the mean and covariance of the model function, and determines a parameter value for the next observation, using the acquisition function. A data acquirer (13) sets the parameter value in the analyzing system (20) and acquires a corresponding observed value. A loop process with the feedback of the observation data is repeated to determine an optimal parameter value.
