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...
