Benefits of technology

This technology allows us to measure accurately different types of materials with less manual effort compared to previous methods like weighing or measuring them manually. It also makes it easier than previously possible because there's no need to wait until all measurements have been completed beforehand. Overall, this new technique simplifies the way researchers compare and analyze material properties better while still being able to make accurate calculations faster.

Problems solved by technology

This patented describes different ways to determine how well a specific material contains some atoms called metal. These techniques involve analyzing the atomic weight distribution of these materials beforehand, calculating their densities based upon measurements from various means such as gravimetric analysis or X ray absorption spectrometry. By comparing the resulting values against each other, the concentration of metals may vary due to factors like humidity. To calculate the density value correctly without collecting any data, there must be quick and reliable way to perform the calculations.

Abstract

The invention discloses a method for rapidly measuring the density of a solid insusceptible to absorbing water, comprising the following steps of: during the measurement of the density of the solid, firstly, enabling the temperature of deionized water in a container holding the deionized water to be consistent with the room temperature, measuring the temperature T of the deionized water by using a thermoelectric couple, transmitting the temperature T to a computer by using a temperature acquisition system, acquiring the density rho0 of the water by the computer, wherein the fluctuation of the temperature and the volume of the deionized water is avoided during the measurement; and secondly, sequentially measuring the mass M of the solid to be measured, the mass M1 of the container after a rustproof metal wire suspending mesh bag is immersed into the deionized water and the mass M2 of the container after the solid to be measured is immersed into the deionized water by adopting the rustproof metal wire suspending mesh bag through using an electronic balance, and directly obtaining the density rho of the solid after inputting to the computer . The invention has the advantages of instantaneousness, accuracy, standard and more reasonable operation process. By using the method, the densities of various solids insusceptible to absorbing water can be rapidly and conveniently measured.
