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 …

Gas pycnometry is an analytical method used to determine the volume and density of various types of solid samples. Helium is the gas most commonly used during the measurement, …

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 …

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

With a pycnometer (Greek, „gauged vessel”) the amount of a certain medium (liquid or Helium or other analytical gases) displaced by a solid can be determined.

A gas pycnometer determines the volume of a material by measuring the pressure change of an inert gas within two calibrated volumes. Density is calculated from the measured volume along …

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 …
