METHOD AND DEVICE TO ESTIMATE LEVEL OF ASH CONTENT IN BIOLOGIC MATERIAL Russian patent published in 2015 - IPC G01N23/83 

FIELD: instrumentation.

SUBSTANCE: scope of application: to measure ash content of the biologic material by automatic or semi-automatic method. The essence of invention is that method includes stages of the biologic material scanning using the electromagnetic radiation by at least two energy levels; determination of radiation extent transferred via the specified sample of the biologic material at specified energy levels, and estimation of moisture content of the biologic material based on ratio between specified determined radiation extent transferred via the biologic material at specified energy levels. Then ash content in the biologic material is estimated based on the specified estimation of moisture content of the biologic material and average coefficients of attenuation for the biologic material upon moisture absence, coefficients of attenuation for combustible part of the biologic material, and coefficients of attenuation for ash in the biologic material at specified energy levels. Besides the appropriate device is described.

EFFECT: accurate estimation of moisture content in material sample within wide range of values.
