CELL FOR MEASURING PHYSICAL PROPERTY OF PARTICLE AND INSTRUMENT FOR MEASURING PHYSICAL PROPERTY OF PARTICLE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a cell for measuring physical properties of particles, capable of reducing a measurement error due to reflected light without applying a reflective coating film when a detection object with high concentration or large absorption coefficient is optically measured without dilution.;SOLUTION: A cell for measuring physical properties of particles, includes a first aperture plate having a first outer face and a first inner face opposite to the first outer face, a second aperture plate having a second inner face and a second outer face opposite to the second inner face and arranged so that the second inner face is opposite to the first inner face, and a gap formed between the first inner face and the second inner face for storing a detection object. In a light transmitting area where light penetrates at least the first aperture plate and the second aperture plate, at least one face of the first outer face, the first inner face, the second inner face and the second outer face is inclined to a part or all of faces of the others.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
