Abstract

The invention discloses a preparation device of a plasticine test sample for capillary spray ionization detection. The device comprises a sample cell (1), a push rod (2) and a diameter adjustment plate (3). The sample cell (1) has a cylindrical structure with an upper opening, the bottom of the sample cell (1) is provided with multiple circular sample cell outlets (104) with different diameters, the push rod (2) is arranged at the upper opening of the sample cell (1), the center of the diameter adjustment plate (3) is connected to the center of the bottom of the sample cell (1) through a rotation connection shaft (4) and a plate body (302) is provided with a sample outlet (303). The preparation device can fast and conveniently prepare the plasticine test sample for capillary spray ionization detection and put the plasticine test sample into a borosilicate glass capillary so that the subsequent analysis and test can be finished.

Description

technical field [0001] The invention relates to the field of toy quality and safety testing, in particular to a device for preparing plasticine samples to be tested. Background technique [0002] my country is the world's largest toy producer and exporter. my country's toy exports account for about 60% of the world's total, exceeding the sum of other countries. my country is also the world's largest consumer of toys. According to the results of the sixth national census, there are more than 200 million children aged 0-14 in my country, accounting for 16.6% of the population. In this context, the safety of toy products is very important, and all relevant parties such as manufacturers, management agencies and consumers attach great importance to it. Among toy products, plasticine toys are an important toy product. According to the requirements of relevant laws and regulations, no harmful substances can be detected in plasticine toy products, so as to avoid serious harm to t...
