OPTICAL DEVICE FOR MEASURING OPTICAL PROPERTIES OF A SAMPLE AND METHOD RELATING THERETO

摘要

A device for measuring optical properties of a sample comprises a housing surrounding a flow-cell The flow-cell has a sample inlet positioned proximate to a first end of the flow-cell and a sample outlet positioned proximate to a second end of the flow-cell A sample chamber is positioned between the sample inlet and the sample outlet A plurality of excitation sources are positioned on the housing in an operable relationship to the sample chamber At least one excitation source has a wavelength that is different from the other sources At least one fluorescence emission detector is positioned m an operable relationship to the flow-cell The fluorescence emission detector detects a continuous broadband spectrum of emission wavelengths emitted from the sample upon excitation by each excitation source The device may incorporate at least one absorbance detector for measuring transmitted power that is spectrally dependent on the absorbance characteristics of the sample.
