AbstractThe calculation of the molecular column density from molecular spectral (rotational or ro-vibrational) transition measurements is one of the most basic quantities derived from molecular ...

A common question arises: can density be determined using the free space measured on a gas adsorption analyzer, rather than a device specifically designed for density measurement? This article ...

Compressibility(C p): Compressibility is a calculation of a powder’s unit volume change after applying pressure. C p =100(ρ T −ρ B /ρ T) In this video, Shelly Zhang from Bettersize instrument teaches ...
