Embodiment Construction

[0047] In order to make the present invention more comprehensible, a preferred embodiment is described below in detail with the accompanying drawings.

[0048] Raman spectroscopy rapid detector should have basic requirements such as convenience, mobility and fast detection. Therefore, the Raman spectrometer should be defined from the perspective of actual use of the instrument, which mainly means that it can directly measure the sample quickly and give the result within 20 minutes. It can be used continuously for more than 4 hours without external power supply. The Raman spectrometer that is easy to carry and does not need to be recalibrated. Corresponding to this, its related technical indicators are also specified and required from the perspective of rapid detection.

[0049] Such as figure 1 As shown, the evaluation method of a rapid Raman spectroscopy detector of the present invention includes the following steps:

[0050] Step 1. Determine that the instrument to be evaluated i...

Description

Technical field [0001] The invention relates to the field of instrument evaluation standards, in particular to an evaluation method of a Raman spectrum rapid detector. Background technique [0002] Raman spectroscopy technology is one of the most important spectroscopy techniques for analyzing various molecular structures and identifying substance types. The Raman spectroscopy rapid detector with Raman spectroscopy technology as the core is an instrument that uses the principle of Raman spectroscopy for rapid on-site detection. The instrument is composed of a kit (the instrument that needs to use an enhanced matrix for sample measurement includes the kit), excitation light source, scattered light collection system, spectroscopic system, detection system, control and data processing system, and standard map database. Convenient on-site detection requirements, miniaturization, low cost, combined with enhanced modules to achieve high-sensitivity detection and other characteristics, ...
