Embodiment 2

[0059] see Figure 4 , the composition and structure of this embodiment and embodiment 1 are basically the same, the difference is that in embodiment 1, there are only 4 sample vials 4 and 2 detection vials 7, and two detection holes 6-1. In this embodiment, each arm 13 is provided with two sample pools 4' and two pump chambers 5', and a detection bottle 7 and a detection hole 6-1 are respectively arranged between the four arms 13. Each arm corresponds to a vial, or adjacent arms each have a vial corresponding to a vial between the arms. In this way, 4 groups of samples can be measured at one time.

Embodiment 3

[0061] see Figure 5 , the basic mechanisms of this embodiment and embodiment 1 are basically the same, the difference is that in embodiment 1, there are four sample bottles 4 and two detection bottles 7, and two detection holes 6-1, while in this embodiment In the example, four sample bottles 4 and four detection bottles 7 are provided, and each detection bottle 7 is provided with a detection hole. The detection bottles 7 are spaced between the angles of the arms. This embodiment is suitable for the application of ordinary nanoparticles.

Description

technical field [0001] The invention mainly relates to a control device for reducing manual participation and increasing automatic operation in the process of Raman spectrum detection, especially the detection process of samples by plasmon-enhanced Raman spectrum instruments. The utility model belongs to the field of automatic equipment for spectrum detection. Background technique [0002] Surface-enhanced Raman spectroscopy is a very powerful and highly sensitive analytical technique. It can detect and analyze various molecules adsorbed on the surface of a substance. For some systems, its sensitivity even reaches the single-molecule level. However, its application is very limited - only a few metals (gold, silver, copper) can produce such a strong surface-enhanced Raman scattering effect. [0003] Academician of the Chinese Academy of Sciences, Professor Tian Zhongqun's research group from the School of Chemistry and Chemical Engineering of Xiamen University proposed the e...
