| Abstract: | For the measurement methods of powder samples or muddy samples using infrared spectrometry, we proposed the scattering dilution method and scattering filter method. In our methods, the fabricating pellets are made by pressing mixed alkali halide powders (KBr/CsI). That is why the dilution powder's (KBr/CsI powders') packing ratio becomes almost 100%, thus giving the pellets a sufficient scattering effect. These methods have novel advantages versus transmission or diffuse reflectance methods although our proposal has much criticism and negative comments. |
