The Pycnomatic ATC device is suitable for solids and powders and it is the most accurate technique for real density measurement. Helium is a noble gas with a very small dimension of mono-atomic molecule that can permeate into even extremely narrow pores in tested samples, thus permitting determination of the real volume occupied by a material. The ratio of the dried mass and its volume gives as a result the real density of tested material."@en . . "2"^^ . . "Nen\u00ED k dispozici"@cs . . "2"^^ . "51;54" .
