Abstract
The present invention is one which reduces running costs by eliminating the need for a catalyst, which is a consumable item, and comprises a measurement cell into which sample gas is introduced, an infrared light source that irradiates the measurement cell with infrared light, an infrared light detector that detects infrared light that has passed through the measurement cell, and a gas filter within which a plurality of interference components that interfere with a measurement component in the sample gas are enclosed.
Claims7
An infrared gas analyzer, comprising:
- a measurement cell into which sample gas is introduced;
- an infrared light source that irradiates the measurement cell with infrared light;
- an infrared light detector that detects infrared light that has passed through the measurement cell;
- and
- a gas filter within which a plurality of interference components that interfere with a measurement component in the sample gas are enclosed.
An infrared gas analysis method of analyzing a measurement component in a sample gas by irradiating a measurement cell into which the sample gas has been introduced with infrared light and detecting the infrared light that has passed through the measurement cell with an infrared light detector, wherein
- interference effects of a plurality of interference components on the measurement component are reduced by using a gas filter within which the plurality of interference components that interfere with the measurement component are enclosed.
