Abstract:
A device for determining one or more parameters of interest for raw materials, intermediates and products of bioalcohol production, comprising a sample presentation unit, a source of radiation and a means of detection characterised in that the source of radiation and the means of detection are configured for recorded one or more spectral characteristics in the spectral region from 1000 cm-1 to 5000 cm-1.
Abstract:
A method of determining components of a flowing heterogeneous sample comprising obtaining a sample of material; measuring mid-infrared attenuation values of the sample and calculating in a data processing unit an indication of the component of interest in the sample from the measured mid-infrared attenuation values characterised in that the method further comprises flowing the sample; concurrently interacting mid-infrared radiation with the flowing sample in a measurement region and subsequently measuring the mid-infrared attenuation values for one or more wavebands of the interacted radiation.
Abstract:
A device for determining one or more parameters of interest for bioalcohol liquors comprising a sample compartment (202), a source of infrared radiation (200), a means for detection (204) of one or more one or more spectral characteristics in the spectral region from 400 cm -1 to 4000 cm -1 , and a means of data processing (206) characterised in that the sample presentation unit is arranged to provide an optical interface for absorption spectroscopy and the means of data processing (206) is specifically configured to predict said one or more parameters of interest from said one or more spectral characteristics.
