Problems solved by technology

However, the fragrance substances detected in these matrices are only individual individuals and do not form a system, nor do they cover the allergic fragrances defined by the new EU Toy Directive
At the same time, there is currently no detection method for allergenic fragrances in toys at home and abroad.

Embodiment 1

[0028] Sample preparation and determination methods for 45 allergic fragrances in soap for children:

[0029] (1) Extraction:

[0030] Accurately weigh 22.15mg (accurate to 0.01mg) of the sample, put it into the quartz tube of the sample heat treatment instrument with clean stainless steel tweezers, then insert the adsorption tube loaded with adsorbent into the sample heat treatment instrument, turn on the carrier gas, and the flow rate is 300mL / min. Set the temperature at 55°C, process the sample for 5 minutes, then rapidly raise the temperature to 70°C, keep it for another 5 minutes, and finally raise the temperature rapidly to 85°C, and keep it for 10 minutes. Then put the adsorption tube into the thermal desorption autosampler for testing. The method parameters used are shown in Table 1 and Table 2 respectively:

Abstract

The invention relates to the fields of analytical chemistry and toy safety, in particular to a method for detecting multiple allergic aroma agents in toys, and is mainly the sample preparations and gas chromatography / mass spectrometry for the contents of 45 allergic aroma agents in various toys. The number and type of the allergic aroma agents are various; the boiling point range of the aroma agents is wide, and the requirements for quantity limit are high, so that how to perform simple, fast, efficient and green detection is a great challenge; the method in the invention overcomes the shortages of the existing method by thermal desorption preparation technology and gas chromatography / mass spectrometry technology; a detection method of multiple allergic aroma agents in toys is built; and the method can synchronously detect the contents of 45 allergic aroma agents in toys conveniently, fast, accurately and efficiently.

Description

technical field [0001] The present invention relates to the fields of analytical chemistry and toy safety, and in particular relates to a detection method for the content of various allergic flavoring agents in toys, mainly various toys (comprising soap for children, plush toys, plastic toys, plasticine, Sample preparation and gas chromatography-mass spectrometry determination of 45 allergic fragrances in rubber, etc.). Background technique [0002] The quality and safety of toys is directly related to children's physical and mental health. Therefore, as people pay more attention to children's products, toy safety has become a hot topic. In recent years, the quality safety and potential safety hazards of children's toys have attracted more and more attention from all over the world. Many foreign countries, especially more developed countries, have strict management on the quality and safety of children's toys, and the safety requirements for toys are becoming more and more s...
