A waveform processing assistance device includes an acquirer that acquires a plurality of waveform data obtained by an analysis of a sample, a selector that selects reference data among the waveform data, an extractor that extracts correct answer peaks and correct answer data from the reference data a determiner that determines each processing section including a correct answer peak and each parameter initial value, a waveform processor that performs waveform processing in each determined processing section based on each parameter initial value, an adjuster that generates a parameter adjustment value at which a waveform processing result obtained in each processing section matches or approximates corresponding correct answer data, and a program creator that creates a waveform processing execution program that includes an instruction to execute waveform processing using the parameter adjustment value in each processing section.

Waveform processing assistance device and waveform processing assistance method

Provided is a mass spectrometer including: a measurement condition setter () configured to set a plurality of measurement conditions which are different from each other in terms of the set value of at least one measurement parameter; a measurement executer () configured to acquire a plurality of sets of mass spectrometric data respectively corresponding to the plurality of measurement conditions; a product ion extractor () configured to extract product ions detected with intensities exceeding a previously determined reference value; an MRM spectrum element information creator () configured to determine the mass-to-charge ratios and measured intensities of the extracted product ions, the mass-to-charge ratio of the precursor ion, as well as the measurement condition, and to create a plurality of pieces of MRM spectrum element information; an MRM spectrum composer () configured to compose an MRM spectrum from the mass-to-charge ratios and the measured intensities of the product ions included in the plurality of pieces of MRM spectrum element information; and a library data creator () configured to relate the MRM spectrum to information concerning the target compound to create library data for the target compound.

Mass spectrometer and mass spectrometric method

A control device for automatic analysis including a unit which stores an analysis parameter file in which setting values of multiple setting items related to analytical equipment control are specified; a unit which describes at least identification information for the sample to be analyzed and the analytical parameters file to be used for analysis, for multiple analyses to be executed in the analysis device, and generates an analysis schedule table which describes setting values relating to one or more of the multiple setting items contained in the analytical parameters file for each analysis; and a control unit which controls the operation of the analytical equipment according to the analysis schedule table. The control unit is made such that the setting values specified in the analysis schedule table are applied preferentially for setting items for which the setting value is described in both the analytical parameter file and analysis schedule table.

Automatic analysis control device and program

Sequential identification numbers are automatically provided and undisplayed, constant, unique numbers are assigned to each event registered in an analysis condition setting table. Since correspondence information between the identification numbers and the unique numbers changes due to the reassignment of identification numbers when an event is deleted from the table, event identification numbers for each compound are changed by referring to the correspondence information on a compound information table. As a result, it is possible to avoid the misalignment of event identification numbers between both tables. In addition, when an instruction is given to coordinate the time information or m/z information on both tables, the information on one table is reflected on the other table in accordance with the identification numbers.

Chromatograph mass spectrometer

Provided is a preparative separation liquid chromatograph system and preparative separation condition searching method which allows for an easy setting of the preparative separation condition. A sample temporally separated into components by a separation column is introduced into a detector and a fraction collector, with each component fractionated and collected by the fraction collector based on the result of a detection by the detector. A controlling and processing unit holds the following data for each sample or compound in the form of a database: chromatogram data obtained when a liquid chromatograph analysis in a preparative separation condition searching mode is performed for various standard samples under a search condition; and chromatogram data obtained when a liquid chromatograph analysis in a preparative separation mode is performed under one or more sets of preparative separation conditions for the various standard samples, along with the preparative separation condition used in this analysis.

When an analysis is finished in the GC/MS, which is an analyzing apparatus, and a file including the data obtained by the analysis is created by the analysis data file creator, the file transfer processorsends the file to the web serverby way of the intranet. The file transfer processorconverts the data received into a format capable of being posted on a web page and stores it in the memory, and simultaneously notifies the analysis unitof a link address for reading it out. The e-mail creation processorcreates an e-mail with the link address in the body and sends it to a predetermined mail address. The user receives and opens the e-mail on the mailerof the client terminaland clicks a link address corresponding to the desired analysis data. In response to this operation, the web serversends the corresponding data to the terminal, which allows the analysis data to be viewed by the web browser
