Description

technical field [0001] The invention belongs to the technical field of metering, and relates to a quantitative sampling device, in particular to a quantitative sampling device for soil thermoluminescence measurement samples. Background technique [0002] In soil thermoluminescence measurement, it is necessary to quantify the samples in order to ensure the comparability of the measured data. However, the number of the same quantitative samples required for each sample measurement is as many as several hundred to one thousand. If a balance is simply used to weigh and determine the samples, not only a highly sensitive balance is required, but also multiple weight adjustments are required. The speed is time-consuming and labor-intensive. Existing quantification techniques usually directly use quantitative funnel or quantitative cup for sample quantification, or combine quantitative funnel (cup) for design, such as application number CN200820156029.9, title "A High-precision Qua...

AI Technical Summary

Problems solved by technology

For example, if quantitative funnel or quantitative cup is directly used for sample quantification, there are often operational errors, and the latter two quantitative devices have relatively high requirements on the fluidity of the quantified substance, so it is very important to develop a sample quantitative sampling device for soil thermoluminescence measurement. necessary
