Bulk density

Thereby the measured variable is the proportion of the outgoing intensity to the incoming intensity after the transmission respectively absorption of the sample. The different molecule groups and chemical combinations of the sample are caused to oscillate at characteristic wavelengths of the infrared light. By measuring the progression of the transmission respectively the absorption of a defined wavelength range specific transmission or absorption bands can be matched to appropriate molecule groups and hence this result can be used for a structure determination of the sample. Usually the evaluation is simply done automatically by the comparison of the spectrum with an IR-database.
