Abstract

Measurement systems typically use the overflow method of Arquimedes, but it has the inconvenience of moisten the sample due to the immersion, and also has a relatively low resolution. This project contributes to a study already undertaken on a system of volumetric measurement capable of measuring the volume of the dry samples with relatively high resolution (~ 100 microliter). The Work Plan is the realization of new measurements with samples of standard volume to complete and close a calibration curve by using nitrogen gas. (AU)
