(Example 4)
Next, a fourth embodiment of the present invention will be described.

  7A is a top view of the heating parts 15A and 15B (top view of the top heating parts 151A and 151B), which is a main part of the fourth embodiment of the present invention, and FIG. It is a top view which shows the modification of Example 4 of invention.

  As shown in FIG. 7A, the heating parts 15A and 15B have a half-moon shape when viewed from above, and cylindrical parts 152A and 152B projecting upward are formed near the center of the upper surface.

It is also possible to configure. If comprised in this way, many types of substances can be detected with high accuracy from a plurality of three or more portions of the test piece.

  In the drug trace detection device, as in the present invention, a mechanism for vaporizing at two different temperatures is provided according to a temperature condition in consideration of the vaporization temperature and decomposability of the sample. A plurality of drugs can be detected by the detection operation. In particular, in a detection device having a polarity switching function, there is a great difference in vaporization temperature and decomposability of substances that are likely to be positive ions or negative ions, so that ions of different polarities can be detected by a single detection operation. Even if it is unipolar, there may be a difference in vaporization temperature and decomposability depending on the substance, and it can be expected to detect multiple substances.

  In addition, since drugs such as narcotics, stimulants and dangerous drugs can be measured with high throughput and analytical reliability, it can be applied to high-speed processing of multiple samples. For example, it can be used at inspection sites and laboratories for anti-smuggling such as customs and airports.
