| titleOfInvention | Absorptiometer and analysis method |
| abstract | (57) [Summary] [Purpose] A compact, potable, and inexpensive absorptiometer that can measure colored substances adsorbed on an adsorbent with high sensitivity and accuracy and that can be used for analysis and evaluation at sampling sites. Provided analysis method. [Structure] Semiconductor laser emitting monochromatic light is a measurement light source 1 In addition, a tungsten lamp that emits white light is used as the correction light source 2, and the light from each light source is alternately irradiated to the sample, and the absorbance with the measurement light and the absorbance with the correction light are measured to determine the difference in absorbance between the two light sources. As the measured value, the concentration of the unknown sample is determined based on the calibration curve prepared in advance with the sample of known concentration. The measurement light source is a semiconductor laser with a large output per wavelength, and the correction light source is white light that is not monochromatic. It can be detected by the amount of light, improving the measurement accuracy and sensitivity. |
