METHOD AND SYSTEM FOR USE IN MONITORING BIOLOGICAL MATERIAL

摘要

The invention provides a system and a method for detection of microorganisms in a biological material. The method includes applying non-invasive in-situ optical measurements to a dead space free portion of a container containing the biological material, by illuminating the region of interest with light including at least first and second wavelengths of substantially narrow spectra corresponding to respectively an absorption peak of at least one metabolic gas and a spectral region outside the absorption peak of the metabolic gas, and measuring transmission of the first and second wavelengths through said dead space. The method also includes analyzing measured transmission data and generating data indicative of the metabolic gas concentration. The generated data being thereby indicative of microorganisms in the biological material.
