At least one stable isotope reagent is added to each biological sample and standard sample to prepare biological samples for analysis and standard sample for analysis. The quality of the biological samples is evaluated using data of one set of biological samples for analysis composed of a plurality of biological samples for analysis. Besides, the quality of a pretreatment and/or analysis of each set of samples for analysis is evaluated using data obtained by analyzing the standard sample for analysis before and after an analysis of one set of samples for analysis. An abnormality in a chromatograph or mass analyzer used for the analysis of one set of samples is evaluated by the data obtained by analyzing a sample for device evaluation before and after the analysis of one set of samples for analysis. Thus, the quality of data obtained by chromatographic mass spectrometry on biological samples is comprehensively evaluated.

Method and device for chromatographic mass spectrometry

A laser tip, a laser treatment tool, a laser treatment device and a laser treatment system are provided for performing laser treatment surgery and minimizing any bleeding. A laser tip is attachable to a laser radiation opening located at the tip end of a laser transmission tube. The laser tip includes an attaching portion detachable from the laser radiation opening and a contact portion contactable with biological tissue. The contact portion is at the front of the attaching portion in the direction in which the laser light exits the laser radiation opening. An open space is located between the contact portion and the attaching portion, and a coupler couples a part of the contact portion and a part of the attaching portion. The contact portion has a reflective surface at a rear end thereof which reflects the laser light toward the coupler.
