Density-100 Pycnometer Density Analyzer Introduction

True density is one of the important parameters in measuring physical property of solid materials, especially for powder. Value of true density depends on material purity and compactness which affect the quality of sample. The traditional measuring way of true density is based on Archimedes water displacement method. As its serious inaccuracy of manual operation and drainage exists, the ISO (International Standard Organization) official implemented gas displacement method (ISO 12154) to test the true density in 2014.

If the material has no porosity, the true density can be measured by displacement of any fluid in which the solid remains inert. The accuracy of the method is limited by the accuracy with which the fluid volume can be determined. Usually, however, the pores, cracks, or crevices of the material will not easily be completely penetrated by a displaced liquid. In these instances, the true density can be measured by using a gas as the displaced fluid if the material does not contain closed pores, which cannot be penetrated by the analysis gas. Therefore, the density experimentally determined by gas pycnometry generally is the so-called skeleton density of the material which equals the true solid-state density only for samples without closed pores --- cite from ISO 12154.

Density-100 true density analyzer can quickly and accurately produce true volume and true density for various solid materials such as powders, particles, fibers and blocks. The sample chamber volume range is from 1 ml to 100 ml. It takes about 3 minutes to complete analyses without influencing accuracy.
