Title:
GAS DETECTOR
Document Type and Number:
Japanese Patent JP2023142212
Kind Code:
A
Abstract:
To provide a gas detector capable of detecting a gas component in a gas sample.SOLUTION: A gas detector comprises: a first concentrator capable of concentrating first and second gas components. The first concentrator is configured so that, a ratio of concentration rates of the first and second gas components is a first concentration ratio. The gas detector has; a second concentrator capable of concentrating, the first and second gas components. The second concentrator is configured so that, a ratio of concentration rates of the first and second gas components, is a second concentration ratio. The gas detector has a first sensor and a second sensor capable of measuring concentration of the first and second gas components. The first sensor is configured so that, a ratio of measurement sensitivity of the first gas component and measurement sensitivity of the second gas component, is a first sensitivity ratio. The second sensor is configured so that, a ratio of measurement sensitivity of the first gas component and measurement sensitivity of the second gas component is a second sensitivity ratio. The gas detector has a channel forming part which can form: a first gas path extending from the first concentrator to the first and second sensors; and a second gas path extending from the second concentrator to the first and second sensors.SELECTED DRAWING: Figure 1
