Embodiment Construction
[0025] The present invention will be further described below in conjunction with accompanying drawing.
[0026] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the online fluorescence reactor 1 of the present invention is provided with a sample chamber 2, a light inlet 13, a light outlet 20, a fluorescence receiving channel 17, a sampling channel 22, a first channel 36 and a second channel 37, and the sample chamber 2 is located in Between the light inlet 13 and the light outlet 20; the light inlet of the sample chamber 2 is opposite to the light inlet of the light inlet 13, and the light outlet of the sample chamber 2 is opposite to the light outlet of the light outlet 20, so that the light can pass through the light The light enters through the hole 13 , passes through the sample chamber 2 and exits through the light exit hole 20 . A first transparent pressure-resistant device 11 is sealed and fixed between the light inlet of the sample chamber 2 and the li...

The invention discloses an on-line fluorescence reaction kettle. A sample room is positioned between a light inlet hole and a light outlet hole; a light inlet port of the sample room is opposite to a light inlet port of the light inlet hole; a light outlet port of the sample room is opposite to a light outlet port of the light outlet hole; a first transparent pressure-resisting device is hermetically fixed between the light inlet port of the sample room and the light outlet port of the light inlet hole; a second transparent pressure-resisting device is hermetically fixed between the light outlet port of the sample room and the light inlet port of the light outlet hole; a third transparent pressure-resisting device is hermetically fixed in a fluorescence receiving channel; the third transparent pressure-resisting device separates the fluorescence receiving channel into a first section and a second section; the second section is communicated with the sample room; a light inlet port of the first section is positioned on a first side surface of the reaction kettle; a first channel and a second channel are respectively communicated with the sample room; the inlets of the first channel and the second channel are positioned on a second side surface of the reaction kettle; and the first side surface is opposite to the second side surface. The reaction kettle of the invention can be used for simulating on-line detection in a deep sea extreme environment condition.
Description
technical field [0001] The invention relates to an on-line fluorescence reaction kettle, in particular to on-line fluorescence detection for simulating a flow system under extreme deep-sea environmental conditions. Background technique [0002] In the process of biomolecular research, fluorescence method has been widely used because of its advantages of high sensitivity, good selectivity, and can be used for trace analysis. At present, more than 200 elements can be determined by fluorescence method. Fluorescence is widely used in research work in biochemistry, physiology and clinical medicine. The application of fluorescence technology in biochemistry and molecular biology research mainly includes the following aspects: (1) Qualitative substance: Different fluorescent substances have different excitation and emission spectra, so they can be used to identify substances by fluorescence. (2) Quantitative determination: Utilizing the relationship that the fluorescence intensit...
