Description

technical field

[0001] The invention relates to the technical fields of optical platform, analytical chemistry, etc., in particular, the invention relates to a solid sample stage, a spectrophotometer and an LSPR detection method. Background technique

[0002] A spectrophotometer is an instrument for qualitative and quantitative analysis of the substance by measuring the light absorbance of the substance under test at a specific wavelength or within a certain wavelength range. At present, spectrophotometer has been widely used in analytical chemistry, molecular biology and other fields. It usually includes light source, monochromator, sample chamber, detector, signal processor, storage system and display system. The state of the object measured by the spectrophotometer mainly includes two categories: liquid and solid.

[0003] Among them, the liquid substance is usually placed in the cuvette and evenly distributed in the cuvette, so generally only one cuvette is placed in o...
