Abstract
A granular-substance component measuring method comprises steps of emitting detection light to granular substances filled in a space, receiving a reflected light from the granular substances and measuring a component of granular substances by a spectroscopy, and a displacement is given to the granular substances at each measurement, measurements are performed a plurality of times, and measurement results are averaged.
Claims10
A granular-substance component measuring method comprising:
- steps of emitting detection light to granular substances filled in a space, receiving a reflected light from said granular substances and measuring a component of granular substances by a spectroscopy, wherein a displacement is given to said granular substances at each measurement, measurements are performed a plurality of times, and measurement results are averaged.
A granular-substance component measuring instrument comprising:
- a sample holding device with a space in which granular substances are filled and at least one component analyzing instrument mounted on said sample holding device, wherein a detection window is provided in a board facing said space, wherein said component analyzing instrument is configured to irradiate a detection light to said granular substances through said detection window, to receive a reflected light from said granular substances, and to measure components by a spectroscopic analysis, wherein said sample holding device has a displacement giving means for giving a displacement to said granular substances, and is configured to give a displacement said granular substances by said displacement giving means, and wherein said component analyzing instrument is configured to perform measuring granular substances a plurality of times wherein a displacement is given to said granular substances at each measurement and to average measurement results.
