Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as figure 1 As shown, the fluorescence detection device of the present invention includes a detection cell 3 , a transmitting optical fiber 1 , a focusing lens 2 , a receiving optical fiber (not labeled in the figure) and a receiver 6 .

[0017] The detection pool 3 is cylindrical, specifically, it is cylindrical in this embodiment, and the diameter of the bottom surface is 1.2cm-2.0cm; the specific shape and size of the detection pool 3 can be determined according to actual needs, such as an elliptical cylinder shape, Increase the diameter, etc., and it can even be in the shape of a polygonal prism, but these shapes need to pay attention to adding other measures to avoid damage to the fiber due to excessive bending of the fiber when winding the fiber, such as adding some arc-shaped structures. The side wall of the detect...

Description

technical field [0001] The invention relates to a fluorescence detection device, which belongs to the technical field of analysis and detection and is widely used in analytical chemistry, medical detection, environmental protection and the like. Background technique [0002] Fluorescence detection is a commonly used detection technology, which uses the characteristics of the analyte to produce fluorescence when excited by light of a specific wavelength for qualitative and quantitative detection. This method is not only convenient and fast, but also usually has high sensitivity and selectivity, so it is easy to be used for real-time or in situ detection. However, in the current situation, the volume of the general fluorescence detection device is relatively large; and the detection method adopted is that the excitation light is hit on the measured substance, and the fluorescence is received from a position 90° from the excitation light for collection and analysis. Fluorescen...
