Analysis and detection equipment for heavy metal content in cigarette smoke

Abstract

The invention provides analysis and detection equipment for heavy metal content in cigarette smoke. A main machine body of the equipment comprises a sealed air cabinet, a honeycomb cowling, a rotating disc type smoking mechanism, an instrument chamber, a frequency conversion fan cabinet, an operation panel and an airflow switching device, wherein the movable honeycomb cowling is arranged in the middle of the sealed air cabinet to divide the sealed air cabinet into an upper part and a lower part; the rotating disc type smoking mechanism is mounted at the lower part of the sealed air cabinet; the instrument chamber is arranged below the sealed air cabinet; a static catching device is arranged in the instrument chamber; the rotating disc type smoking mechanism can serve the functions of introducing, pushing, igniting and smoking cigarette test samples; the static catching device in the instrument chamber comprises a high-voltage static catching pipe, a carrying manipulator arm, a sprinkling device and other loading mechanisms, catches smoke sediments by using high-voltage static electricity, performs collection and weighing, and analyzes and detects smoke through an extraction liquid. The equipment provided by the invention can effectively realize effective analysis and detection of the heavy metal content in cigarette smoke and ensures the accuracy of detection results.

Description

technical field [0001] The invention relates to a heavy metal content analysis and detection device, in particular to a heavy metal content analysis and detection device in cigarette smoke. Background technique [0002] The main smoke of cigarettes contains trace amounts of heavy metals. It is very important for human health to study, detect and analyze the content of heavy metals in mainstream smoke of cigarettes. For example, the four heavy metal elements of chromium, nickel, cadmium, and lead, and the two non-metallic elements of arsenic and selenium, the possible content of each cigarette is ng / cigarette, and the structure and material of the smoking machine used by ordinary conventional analysis equipment cannot adapt For the detection and research of heavy metal ions, the main problems are as follows: [0003] The metal parts of the smoking machine used in conventional analysis equipment usually contain much higher heavy metal components than the heavy metal component...

AI Technical Summary

Problems solved by technology

When using it as a high-voltage electrode to collect mainstream smoke particulate matter, nickel and cadmium plasma may also cause smoke pollution

At the same time, the smoking machine equipment used for conventional analysis cannot meet the working requirements of the clean laboratory, and the smoke cannot be isolated and sealed during the experiment, and the leakage of the smoke will cause environmental pollution in the clean laboratory

And it is impossible to realize the automatic analysis and detection process, and manual operation will cause problems such as uncertainty of experimental results
