A kind of optical cable surface detection device, including pedestal and being provided with primary detection mechanism and secondary detection mechanism in top, primary detection mechanism includes primary detection base and primary detection mould, mould placing groove is recessed on primary detection base, and first optical cable transmission through-hole is opened in the center of groove bottom, primary detection mould is placed in mould placing groove and is provided with optical cable detection through-hole in the center, secondary detection mechanism includes secondary detection base and multiple detection components, secondary detection base is provided with second optical cable transmission through-hole, multiple detection components are evenly distributed and are arranged on secondary detection base, one end is fixedly connected with secondary detection base, the other end is inserted into secondary detection base and is connected with detection abutting piece by elastic expansion component.The primary detection mechanism in the application carries out rough detection to optical cable surface, is used to filter the larger bulge on optical cable surface, multiple dynamic detection wheels in secondary detection mechanism are arranged in phase and are closely combined with optical cable surface to carry out fine detection, and detection coverage is wide.

This invention belongs to the field of environmental analytical chemistry, specifically a wastewater analysis method for the simultaneous detection of multiple synthetic cannabinoids and their metabolites. This invention employs a micro-volume direct injection method combined with ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS / MS) for qualitative and quantitative analysis of 72 synthetic cannabinoids and their metabolites in wastewater samples. This invention eliminates the need for complex pretreatment processes such as solid-phase extraction, is simple to operate, has a short analysis time, high sensitivity, and wide coverage, making it suitable for high-throughput monitoring of synthetic cannabinoids in wastewater.
