Abstract

The invention relates to the field of material evidence detection, field detection and medical detection, in particular to a liquid sampler for Raman on-site rapid detection. The liquid sampler is characterized by comprising a capillary tube sampling device and a capillary tube fixing device which are fixedly connected; the capillary tube fixing device comprises a capillary tube fixing block; oneside, close to the capillary tube sampling device, of the capillary tube fixing block is provided with a capillary tube inserting hole for inserting the capillary tube sampling device; a Raman probe insertion hole for inserting a Raman probe is formed in one side, far away from the capillary tube sampling device, of the capillary tube fixing block, a light transmission hole is formed between the Raman probe insertion hole and the capillary tube insertion hole, and a thin slide for blocking the light transmission hole is arranged in the Raman probe insertion hole. According to the invention, the amount of liquid required by Raman detection is greatly reduced, the Raman detection limit is improved, the lower detection limit can reach one microliter, and the application scene and range of Raman are expanded.

Description

technical field [0001] The invention relates to the fields of physical evidence detection, on-site detection and medical detection, in particular to a liquid sampler used for Raman rapid on-site detection. Background technique [0002] Raman spectroscopy belongs to the category of scattering spectroscopy, which is produced by the interaction of light and matter. Because Raman spectroscopy and sub-techniques derived from Raman spectroscopy are efficient, simple, non-destructive, low-cost, non-contact, small sample size, no special sample preparation, high repeatability, It is stable and will not cause physical and chemical decomposition and damage to the sample. It has been widely used in chemical industry, biopharmaceutical, medical testing and other fields, and has made many progresses. It is the focus of attention in the field of non-destructive analysis. In Raman detection, the laser is irradiated on the substance to be detected, and the Raman signal emitted by the subst...
