Japanese Patent JP2023018778
Kind Code:
A
Abstract:
To measure weight of a collected substance, using a filter.SOLUTION: A method, which measures weight of a collected substance using a filter, includes the steps of: measuring weight of only a filter under a plurality of humidity conditions; calculating a regression line expression from the plurality of humidity conditions, and the weight of the only filter measured under the plurality of humidity conditions; calculating the weight of the only filter at specific humidity, using the regression line expression; measuring weight of a filter used in substance collection under the plurality of humidity conditions; calculating a regression line expression from the plurality of humidity conditions, and the weight of the filter measured under the plurality of humidity conditions, and used in the substance collection; calculating the weight of the filter used in the substance collection at the specific humidity, using the regression line expression; and calculating weight of the collected substance by subtracting the calculated weight of the only filter from the calculated weight of the filter used in the substance collection.SELECTED DRAWING: Figure 2
