Automatic True Density Analyzer

• 

Test function

◆ True density testing (powders, granules, blocks, flakes, liquids, slurries, etc.)

◆ Porosity (open porosity, closed porosity) (bulk materials, foam materials, cores, metal components, etc.)

Test principle

◆ Applying Archimedes' principle - gas expansion displacement method, using the Boyle's Law (PV=nRT) of inert gases with small molecular diameters under certain conditions, the true density of the sample is accurately determined by measuring the volume of gas displaced by the sample in the test chamber to precisely determine the skeleton volume of the sample (including closed pores), so the true density is obtained as mass divided by skeleton volume.

◆ The gas expansion displacement method replaces the liquid with gas to measure the volume displaced by the sample. This method avoids the test error caused by sample dissolution in the immersion method and has the advantage of not damaging the sample. Because gas can penetrate into the tiny pores and irregular surface pores of the sample, the measured sample volume is closer to the skeleton volume of the sample, which can be used to calculate the density of the sample, and the test value is also closer to the true density of the sample.

◆ The test system of the instrument consists of a test chamber and a reference chamber, as shown in the figure.
