Embodiment Construction
[0022] (1) Summary
[0023] The drawings to be referred to in the following description of the embodiments are all schematic representations. That is, the dimensional (including thickness) ratios of the respective constituent elements shown on the drawings do not always reflect their actual dimensional ratios.
[0024] The detection method according to the present embodiment is the detection method of the detection device 1 . Such as figure 1 As shown in , the detection device 1 has a detection chamber 10 that forms a part (flow path L1 ) of a flow path of a gas (sample gas). The detection device 1 is configured to detect chemical species present in a gas in a detection chamber 10 . That is, the detection device 1 further includes a sensor 11 provided in the detection chamber 10 and configured to detect a chemical substance contained in the sample gas. The detection device 1 further includes an adsorption part 12 disposed in the detection chamber 10 and configured to adsor...

The purpose of the present disclosure is to reduce the time required to concentrate a chemical substance while simplifying the flow path of a gas. This detection method has a calibration mode, a firstdetection mode, a first adsorption mode, a second adsorption mode, and a second detection mode. In the calibration mode, a sensor (11) is calibrated while a low-concentration gas flows from the sensor (11) toward an adsorption unit (12). In the first detection mode, which follows the calibration mode, a chemical substance is detected while a sample gas flows from the sensor (11) toward the adsorption unit (12). In the first adsorption mode, which is executed to partially overlap in time with the execution of the first detection mode, the chemical substance is adsorbed in the adsorption unit (12). In the second adsorption mode, which follows the first adsorption mode, the chemical substance is adsorbed in the adsorption unit (12) while the sample gas flows from the adsorption unit (12) toward the sensor (11). In the second detection mode, the chemical substance adsorbed in the first and second adsorption modes is separated from the adsorption unit (12), and the chemical substance is detected by the sensor (11).
Description
technical field [0001] The present disclosure generally relates to a detection method, a control system, a detection system and a program of a detection device. Specifically, the present disclosure relates to a detection method of a detection device for detecting a chemical substance present in gas, a control system for controlling the detection device, a detection system including the detection device, and a program. Background technique [0002] As a conventional example, Patent Document 1 describes an odor detector. The odor detector includes: an odor sensor configured to output signals corresponding to various odor substances; an adsorption and desorption part configured to adsorb and desorb a sample gas; The desorbed gas is directed to the odor sensor. In this odor detector, an adsorption and desorption section and an odor sensor are provided independently of each other, and are connected to each other via a flow path (pipe) and a switching valve. [0003] The flow p...
