Abstract: The method and apparatus for detecting a chemical substance of the present invention perform the detection of a chemical substance by capturing the chemical substance with a capturing body prepared by utilizing a molecular template. The present invention provides a chemical sensor easy to use for general consumers at home as well as for medical personnel (medical doctors, medical technicians and nurses). In particular, an object of the present invention is to diagnose the symptom of stress disorder by detecting, with high sensitivity, a steroid hormone such as cortisol closely related to stress disorder, and to herewith contribute to the prevention and early treatment of stress disorder. The present invention provides a molecular template for a steroid hormone, including a polymer to interact with the steroid hormone. The polymer preferably includes, in the polymerization unit thereof, two or more functional groups to interact with the steroid hormone.

Abstract: A mass spectrometer and a mass spectrometry method adapted for mass spectrometry of a hardly volatile minuscule organic foreign matter of several ?m often causing a device defect are disclosed. A sample gasified by a sample heating probe is introduced into an ion source, and the sample thus ionized is detected by being separated in accordance with the mass-to-charge ratio. In this mass spectrometry technique, the sample heating probe is covered with a cylindrical gas guide mechanism, and the gasified sample is led efficiently to the ion source by the gas guide mechanism, thereby making possible the contribution by the sample components which otherwise might be dispersed and wasted in the prior art. As a result, the mass spectrometry with higher sensitivity and S/N than in the prior art is realized.

Abstract: An object of the present invention is to extract a micro foreign body of a few ?m, which may cause a product defect of a device or the like, and to subject the foreign body to a mass analysis at a favorable S/N ratio without any contamination. A micro sample heating probe includes a sample holder made up of two members different in diameter, a supporting part, and a terminal part. The sample holder includes a heating mechanism only in a limited part, and just a region extremely close to the micro sample being an analysis target is heated locally. Therefore, even when a contaminated substance is attached to the probe, such substance is not heated, thereby preventing a noise from occurring, and enabling an analysis at a quite favorable S/N ratio.
