True density is one of the important parameters in measuring physical property of solid materials, especially powder. Value of true density depends on material purity and compactness which affect the quality of sample. The traditional measuring true density of materials is based on Archimedes water displacement method. As the serious inaccuracy of manual operation and drainage exists, ISO (the International Standard Organization) officially implemented gas displacement method (ISO 12154). Densi 100 Series True Density Analyzer can quickly and accurately produce true volume and true density of various solid materials such as powders and blocks. The sample chamber volume range is 1 cm³ - 100 cm³. It takes about 3 minutes to complete analyses without influencing accuracy.

The Micro Series can accurately produce surface area and pore size results of powder materials. According to the different test functions, this series of instruments are divided into three types, there are A, B, and C, the C type is configured with 1 torr or 0.1 torr high-sensitive pressure sensors and turbo molecular pump with ultimate pressure of 10^-8 Pa, it can effectively take microporous analysis of microporous materials such as molecular sieve, catalyst, activated carbon, and other microporous materials.

The main focus of MSI is high resolution glow discharge mass spectrometry (GDMS); a mature, versatile technique for the direct determination of elemental content (matrix to sub-trace) in a variety of materials.

The Acorn AreaTM is a revolutionary instrument designed to measure the surface area of nanoparticles dispersed in a liquid. This patented nuclear magnetic resonance based method offers many advantages in comparison with conventional surface area techniques. Measurements take about 5 minutes from start to finish. No sample preparation such as drying or degassing is required. High concentration dispersions are measured directly; without dilution. Acorn Area measurements are orders of magnitude faster than any other surface area measuring technique.
