Abstract: A quantitative analysis assistant program that creates a quantitative table showing the relationship of compounds, quantitative values and other related information for each of two data files A and B, and displays on each of the view areas “a” and “b”. The analysis operator specifies one compound in one of the quantitative tables. Then, the other quantitative table is automatically searched for a compound having a name identical to the specified compound. A chromatogram, mass spectrum and other related information corresponding to that compound and are based on data file B are displayed on the view area “b” along with the quantitative table. Then, measurement results corresponding to the compound based on data file A are displayed on view area “a” along with the quantitative table. A comparison of the measurement or quantitative determination results for the same component can be easily and efficiently performed in a simultaneous multicomponent analysis.

Abstract: Problem to be Solved To select a marker peak which characterizes a difference between groups, even when the number of samples belonging to each group is small. Solution A peak matrix is created based on the peaks detected from mass spectra of a plurality of samples belonging to a plurality of groups (S1-S3). Each row of the peak matrix represents a peak-intensity distribution for a large number of samples at one mass-to-charge-ratio value. If there is no difference between the groups at a certain mass-to-charge-ratio value, the peak-intensity distribution at that mass-to-charge-ratio value should be a lognormal distribution (or normal distribution). Accordingly, a hypothesis test for the conformity of the peak-intensity distribution to the lognormal distribution is performed for each mass-to-charge-ratio value (S5). A mass-to-charge-ratio value at which a significant difference has been found is selected as a candidate of the marker peak (S6).
Abstract: When a column is attached to an attachment location, first, a ferrule through which the column is inserted is heated and thus is fixed to the column. Then, the column to which the ferrule is fixed is attached to the attachment location. As described, when a user performs work of attaching the column to the attachment location, the ferrule is always fixed to a certain spot of the column. Therefore, it is possible to omit work of holding the ferrule such that the position of the ferrule with respect to the column does not shift when the work of attaching the column is performed. As a result, the column can be easily attached to the attachment location.

A laser beam is excited by the excitation light from the excitation source; a saturable absorber 4 is between the input mirror and the output mirror and increases a transmittance along with an absorption of the laser beam from the laser medium. A wavelength conversion element converts a fundamental wave of the laser light from the output mirror to a higher harmonic. A control element generates a phase-matched signal to adjust the phase-matching between the fundamental wave and the higher harmonic based on the output from the wavelength conversion element and the laser output setting value, and controls the laser output by outputting the phase-matched signal to the wavelength conversion element.
