ABSTRACT:
A dangerous substance detecting apparatus comprises an oven for accommodating a wiping member stuck with a sample derived from a dangerous substance, a light source for emitting infrared rays for heating the sample, an ion source for ionizing the sample evaporated in the oven, a mass analyzer for performing a mass analysis on ions, a data processing unit for processing an output signal from the mass analyzer to determine the presence or absence of a dangerous substance, an operation panel for displaying the result of the determination, an alarm unit for generating an alarm based on the result of the determination, and a control unit for controlling the respective components of the apparatus based on operating conditions entered from the operation panel and specified for the respective components of the apparatus.
