Abstract

The invention relates to the technical field of spectrum detection, in particular to a testing device and method for a to-be-tested sample and an anti-counterfeiting testing method. The testing devicecomprises an atomizing device, an inductively coupled plasma torch generator, a femtosecond pulse laser generator and a spectrum collection module, the inductively coupled plasma torch generator is used for producing plasma torches, the atomizing device is used for converting the to-be-tested sample to aerosol, the femtosecond pulse laser generator is used for forming femtosecond filaments or plasma gratings, and the spectrum collection module is used for collecting electromagnetic wave signals emitted from a plasma and forming a characteristic spectrum of the to-be-tested sample. According to the testing device for the to-be-tested sample, the characteristics of the high efficiency, reliability, high temperature and the like of an inductively coupled plasma torch on substance processingare utilized, the incomparable advantages of instantaneity, rapidity, micro-damage, full-element analysis and the like of a laser breakdown spectrum detection technology are also combined, the interference of a fluorescence background is overcome, the sensitivity of the detection spectrum is improved, and the signal-to-noise ratio of the detection spectrum is increased.

Description

technical field [0001] The invention relates to the technical field of spectrum detection, in particular to a detection device, a detection method and an anti-counterfeit detection method of a sample to be tested. Background technique [0002] In recent years, there has been an increasing demand for the detection of common sample elements, such as the detection of heavy metal elements in water and soil to monitor and control heavy metal pollution, and the detection of various elements in organic matter such as vegetables and tea to evaluate their impact on The impact of ingestion on the human body is good or bad; at the same time, the problem of counterfeiting of various meals and drinks is becoming more and more serious. The authenticity of various drinks and foods can also be analyzed by detecting the characteristic elements in them. [0003] Traditional material analysis and detection usually adopts the method of sampling and processing with laboratory chemical reagents a...
