摘要： A large number of kinds of azo compounds which are representative hazardous substances in fiber products are divided into two groups. The compounds included in the first group are detected by an MRM measurement by a tandem mass spectrometer unit (12) in a measurement section (10) while a two-liquid gradient elution under an acidic condition is performed in a liquid chromatograph unit (11), using an aqueous ammonium acetate solution as mobile phase A, and a mixture of acetonitrile and an aqueous ammonium acetate solution as mobile phase B. On the other hand, the compounds included in the second group are detected by an MRM measurement while a two-liquid gradient elution under a neutral or weakly basic condition is performed using an aqueous ammonium bicarbonate solution as mobile phase A and acetonitrile as mobile phase B. An exhaustive quantitative analysis for major azo compounds can be achieved by performing the two analyses for the same sample. An efficient test with a shortened analysis period can thereby be performed.

摘要： A model for locating a peak portion in a chromatogram or similar waveform is trained by machine learning using multiple sets of partial waveforms prepared by dividing each reference waveform having a known peak position. An analysis-target waveform is divided into partial waveforms, and whether or not a partial waveform is a peak portion is determined for each partial waveform by the trained model, to estimate different kinds of regions in the analysis-target waveform, including an overlap-peak region. For an overlap peak within a region estimated to be an overlap-peak region, whether or not that peak is a multimodal peak originating from one component is determined, using at least the height of a peak in the overlap peak, the depth of the trough between two neighboring peaks, or the horizontal width of the portion between the bottom of the trough and the top of one of the neighboring peaks.

摘要： First product ion spectrum data is acquired by dissociating a precursor ion derived from a sample component by collision between the precursor ion and an inert gas molecule to generate product ions, and detecting the product ions after separating the product ions according to a mass-to-charge ratio; second product ion spectrum data is acquired by dissociating the precursor ion by a reaction of the precursor ion with hydrogen radicals to generate product ions, and detecting the product ions after separating the product ions according to a mass-to-charge ratio; and a set of product ions having a predetermined mass difference is extracted in the first product ion spectrum data and the second product ion spectrum data.

摘要： The present invention provides dielectric barrier discharge ionization, including a dielectric barrier discharge tube and an electrode pair consisting of a first electrode and a second electrode. At least a portion of the dielectric barrier discharge tube is provided between the first electrode and the second electrode. The electrode pair can ionize the sample after the power is turned on. The dielectric barrier discharge tube is in communication with a vacuum portion. The pressure range in the dielectric barrier discharge tube is 0.01 to 100 Pa. The dielectric barrier discharge ionization provided by the invention remedies the defects of existing low-pressure ion sources in the pressure range, and provides the low-pressure ion source with high ionization ability, high versatility and simple devices.

摘要： 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. In the case of a parameter search using a multi-task Bayesian optimization method, the present technique improves the efficiency of the parameter search even if the correlation between the target observation data and reference observation data is low.
