Pycnometer is the preferred spelling in modern American English usage. Pyknometer is to be found in older texts, and is used interchangeably with pycnometer in British English. The term …

In addition to its use in measuring the true density of a powder, pycnometry can also be used to discriminate among different crystalline phases or grades of materials, different alloys, …

Gas pycnometry is a fast, precise, and cost-effective technique for measuring the volume of powders, solid, and liquid materials, enabling reproducible and accurate density determinations.

The density measured by Helium Pycnometry is often referred to as “helium density” implying that open pores excluded in the calculation. Since He cannot access closed pores, they are …

There are usually at least three valves used: the first (V1) to provide gas to the sample chamber, the second (V2) to allow expansion of the gas from sample to reference chamber, and the …

The AccuPyc II determines density and volume by measuring the pressure change of nitrogen within a calibrated volume. This technique is non-destructive as it uses the gas displacement …

Apr 25, 2025 · This guide covers various pycnometer types, including gas pycnometers and those used for solids, semi-solids, and helium pycnometry, explaining their applications in …

Gas pycnometry is a technique used to determine the true volume of a solid material. Unlike methods that measure geometric volume, gas pycnometry accounts for closed pores and …

An inert gases, such as helium, nitrogen, or air are commonly used as the displacement medium for gas pycnometry. A sample is placed in a chamber of known volume, which is sealed and …

Gas Pycnometry provides fast, high-accuracy determination of density, porosity, purity, quality, volatile organic content and more.
