Problems solved by technology

However, most of the current spectrometers are single-spectrum measuring instruments. If you need to measure multiple spectra of samples, you need to use multiple instruments to measure them separately.
[0003] For the analysis of complex samples or the efficient analysis of simple samples, single-spectrum measuring instruments are difficult to meet the requirements

Abstract

The invention discloses an in-situ integrated multi-spectrum measurement system and method. The system comprises an in-situ integrated multi-spectrum induction excitation unit, at least one light source and excitation light focusing unit, at least three spectrum signal detection units, at least one annular track and radial radiation arms matched with the annular track, wherein each arm slides along the track around the corresponding center axle of the annular track, the total number of the radial radiation arms is at least four. The in-situ integrated multi-spectrum induction excitation unit is a surface plasma resonance coupling element and arranged in the center area of the first annular track. The intersecting line of a non-sample contact surface of a surface plasma resonance sensing film and a central symmetrical surface of a surface plasma resonance coupling prism is coincident with the center axle of the first annular track. The light source, the excitation light focusing unit, and the spectrum signal detection units are respectively fixed on the respective radial radiation arms.

Description

technical field [0001] The invention belongs to the technical field of test instruments, and in particular relates to an in-situ integrated multispectral measurement system and a detection method. Background technique [0002] Spectral measurement has developed into a mature detection and analysis method, which is widely used in physics, chemistry, materials, biology, medicine and other fields. However, most of the current spectroscopic instruments are single-spectrum measuring instruments. If it is necessary to perform multiple spectral measurements on the sample, multiple instruments must be used to measure them separately. [0003] For the analysis of complex samples or the efficient analysis of simple samples, single-spectrum measuring instruments are difficult to meet the requirements. Composite multi-spectral simultaneous measurement and analysis is an effective solution. A single measurement can give multiple spectral detection information at the same time, which can...
