Key Properties
Pumice stone granular (for elementary analysis) is a specific granular grade of pumice, a volcanic glass that is formed when lava cools rapidly and traps gas bubbles, resulting in a light, porous material. This product is primarily used as a support or packing material in elemental combustion analysis, particularly in CHN analyzers, where it aids in the accurate measurement of carbon, hydrogen, and nitrogen in organic compounds. Its unique properties, including low density and high porosity, make it an ideal choice for ensuring optimal performance in analytical applications. The granular form allows for easy handling and effective packing in analytical instruments, enhancing the efficiency of combustion processes.
Also known as Volcanic glass, Pumice.

- Substance
Pumice stone granular typically appears as light gray to tan porous granules, characterized by its low density and high porosity. The specific gravity of pumice ranges from 0.5 to 0.9 g/cm³, making it significantly lighter than many other minerals. The material is insoluble in water and most organic solvents, which is advantageous for its use in analytical applications. The average particle size for this granular grade is generally between 0.5 to 2.0 mm, allowing for effective packing in combustion tubes. Pumice does not have a defined melting point due to its amorphous nature, but it can withstand high temperatures typically encountered in combustion analysis.
