Title:
METHOD OF ANALYSING GRANULAR COMPOSITION BY ACOUSTIC EMISSION
Document Type and Number:
WIPO Patent Application WO2002070136
Kind Code:
A3
Abstract:
The present invention relates to a method for acoustic emission analysis of a granular composition comprising a biologically active compound, said method comprising colliding the granular composition with at least one surface transmitting low frequency vibrations, recording low frequency vibration data in range of 10 Hz to less than 50 kHz, arising from the collision, with at least one vibration detector and subjecting the recorded low frequency vibration data to computerized data processing.
