Abstract: A particle size distribution measuring apparatus includes a light source that emits measurement light to a sample accommodated in a cell including a pair of light transmission plates separated from each other, one or a plurality of detectors that detects the measurement light scattered in the sample, and a particle size distribution calculator that calculates a particle size distribution of a particle group included in the sample based on output signals of the detectors. The particle size distribution measuring apparatus further includes a force applying mechanism that moves at least one of the light transmission plates to apply pressure or a shearing force to the sample in the cell, in which the particle size distribution calculator is configured to calculate the particle size distribution at the time when the pressure or the shearing force applied to the sample has changed from a first state to a second state.

Abstract: A particle group characteristic measurement device includes an image acquisition portion that acquires images of a particle group, a particle information extraction portion that processes acquisition images acquired by the image acquisition portion, and then extracts particle information which is information about particles appearing in the acquisition images, and a particle group characteristic calculation portion that calculates a particle group characteristic at a plurality of time points in a time series based on the particle information extracted from a plurality of the acquisition images acquired prior to respective time points. The particle group characteristic calculation portion calculates the particle group characteristic at each time point based on the plurality of acquisition images used to calculate the particle group characteristic at time points previous to that time point, and on the particle information extracted from the plurality of acquisition images whose image acquisition time periods partially overlap each other.

Abstract: An element analysis method is capable of maintaining accuracy of zero-point correction equivalent to that in the related art while shortening the time required for element analysis. The method includes heating a sample placed in a crucible in a heating furnace, and measuring an amount of an element contained in a gas discharged from the heating furnace by an analysis mechanism to analyze the element contained in the sample. The method includes: a blank measurement step of measuring the amount of the element contained in the gas discharged from the heating furnace when only the crucible is heated; and a step of setting an amount of zero-point correction based on a measurement value in a transient state region where the measurement value rises in blank data obtained in the blank measurement step.
