Embodiment 1
[0055] The embodiment of the present invention provides a method for measuring the content of complex solution components by dual optical path and multi-position fluorescence spectroscopy. The devices used are such as figure 1 As shown, it includes: a fluorescent excitation light source 3 , a packaging bag 5 , a displacement platform 6 and a spectrum receiving device 7 .
[0056] Wherein, ensure that the light outlet of the fluorescence excitation light source 3 and the incident slit of the spectrum receiving device 7 are close to the packaging bag 5, the fluorescence excitation light source 3 is under the two optical paths at the position a: position a (corresponding to the first optical path 1) and position a' (corresponding to the second optical path 2) to excite the complex solution sample in the packaging bag 5, and the fluorescence spectrum is collected by the spectrum receiving device 7; then the fluorescence excitation light source 3 is controlled by the displacement pl...
Embodiment 2
[0065] The difference between the embodiment of the present invention and embodiment 1 is only that the fluorescence excitation light source 3 and the movement mode of the spectrum receiving device 7 are different, see the following description for details:
[0066] see figure 2 , to ensure that the light outlet of the fluorescence excitation light source 3 and the incident slit of the spectrum receiving device 7 are close to the packaging bag 5, the fluorescence excitation light source 3 excites the complex solution sample in the packaging bag 5, and the spectrum receiving device 7 is placed at position a Fluorescence spectra of positions a and a' are collected under dual optical paths. The spectrum receiving device 7 is controlled by the displacement platform 6 to move to position b, and the fluorescence spectrum under the double optical path at position b is collected, namely: the fluorescence spectrum at position b and position b'; the spectrum receiving device 7 is contr...
Embodiment 3
[0071] During specific implementation, due to the limitation of the space structure, it may occur that the fluorescence excitation light source 3 and the spectrum receiving device 7 cannot be close to the packaging bag 5. At this time, an optical fiber can be respectively arranged at the fluorescence excitation light source 3 and the spectrum receiving device 7 , as the incident fiber 4 and the exit fiber 8 .
[0072] see image 3 , the fluorescence excitation light source 3 excites the complex solution sample in the packaging bag 5 through the incident optical fiber 4, the fluorescence spectrum is collected by the spectrum receiving device 7 through the outgoing optical fiber 8, the incident optical fiber 4 and the outgoing optical fiber 8 are respectively close to the packaging bag 5, and the incident optical fiber 4 At position a, the fluorescence excitation light source 3 excites the complex solution sample through the incident optical fiber 4 under the double optical path...
