Plasma device and device and method for quality inspection of children's toys

Abstract

The invention provides a plasma device and a device and method for quality inspection of children's toys, and the method comprises the steps: an in-situ ionization ion source which comprises an insulating pipeline, a high-voltage alternating current system and an insulating housing, wherein the insulating pipeline is arranged in the insulating housing, the high-voltage alternating current system is arranged at one end of the insulating pipeline, and the high-voltage alternating current system is selectively turned on or turned off according to actual requirements; a paper chip sampling system which comprises a paper chip, a first reel, a second reel, a first pulley and a second pulley, wherein the first reel, the second reel, the first pulley and the second pulley are separately arranged on the insulating shell at intervals, and the first pulley and the second pulley are arranged between the first reel and the second reel. The invention also relates to a mass spectrometer comprising the ionization device. The ion source is used for mass spectrometric analysis of the ionized ion source, and solves the technical problems of high throughput and lack of simplicity and convenience in detection of toy products in the prior art.

Description

technical field [0001] The invention relates to the technical field of safety analysis of children's toys, in particular to a rapid mass spectrometry detection of prohibited additives in children's toys. Background technique [0002] In the production process of commercial products, in order to improve the performance of materials, a large number of chemical additives are often added to raw materials. Common chemical additives include plasticizers, allergenic fragrances, carcinogenic aromatic amines, flame retardants and heavy metals to enhance their flexibility. , durability, or flame retardancy. Since a variety of additives and materials are not chemically bonded, in repeated daily contact, chemicals in toys can easily migrate into the human body through various channels, such as the digestive tract, respiratory system, or ingestion through skin and eye contact. Children's health is often more vulnerable to harmful chemicals than adults. Compared with physical injuries, ...
