Abstract

A terminal system has a mass spectrometric for inspecting of dangerous substances is installed in an inspection area, and a support system for determining whether or not a dangerous substance is present and identifying the type of the substance, based on the mass spectrometric data on the target element that has been measured by the mass spectrometric, is installed in a security service enterprise'"'"'s office. Both systems are connected to each other via a communication network so that they can exchange information. Thus, the support system can send the determination result of dangerous substances and a precautions guide to the terminal system via the communication network.

Claims
