Infrared analyzer |
摘要 |
An infrared analyzer where infrared radiation is passed through a measurement cell containing a material that includes a component that absorbs infrared radiation. The radiation exiting the measurement cell passes into a first detector, through an optical filter to a second infrared radiation detector. By analyzing the outputs from each detector and by knowing the characteristics of the optical filter, the concentration of certain infrared absorbing components in the material can be determined.
