Embodiment Construction

[0055] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0056] refer to figure 1 , the present invention proposes a method for simultaneously detecting bisphenol A, bisphenol F, and bisphenol S content, comprising the following steps:

[0057] S10, pretreating the sample to obtain a sample to be tested;

[0058] S20, using LC-MS / MS to detect the sample to be tested, and obtain one or more contents of bisphenol A, bisphenol F, and bisphenol S.

[0059] In step S10, the pretreatment method can refer to GB 5009.156-2016 "National Food Safety Standard General Rules for Pretreatment Methods for Migration Tests of Food Contact Materials and Products" and GB31604.1-2015 "National Food Safety Standards General Rules for Migration Tests of Food Contact Materials and Products" , choose the appropriate food simulant liquid, test temperature, test time and test sample liquid ratio, ...

Abstract

The invention provides a method capable of simultaneously detecting the contents of bisphenol A, bisphenol F and bisphenol S. The method comprises the following steps: pretreating a sample to obtain a sample to be detected; detecting the sample to be detected by LC-MS / MS to obtain one or more of the contents of the bisphenol A, the bisphenol F and the bisphenol S. By the method, the three substances, namely the bisphenol A, the bisphenol F and the bisphenol S, can be rapidly, accurately and quantitatively determinated, the lowest detection limit can reach 0.01mg / kg, the detection time is saved, the workload of detection staff is reduced, batch treatment is easy to implement, and the detection efficiency is greatly improved; a used consumable is low in toxicity, an extracting reagent is small in dosage, contact risks of a tester are reduced, and the consumable consumption and the waste liquid treatment cost are significantly reduced.

Description

technical field [0001] The invention relates to the field of instrument analysis, in particular to a method capable of simultaneously detecting the contents of bisphenol A, bisphenol F and bisphenol S. Background technique [0002] In the field of food contact materials, bisphenol S is a substitute for bisphenol A, and its safety has always attracted people's attention. [0003] Studies have shown that the effect of bisphenol S on the estrogen produced by organisms is similar to that of bisphenol A, and it is also an endocrine disruptor (environmental hormone) that can disrupt the reproductive system. The determination of bisphenol S (BPS) migration is a scientific way to evaluate the safety of food contact materials. my country's GB 9685-2016 "National Food Safety Standard for the Use of Additives in Food Contact Materials and Products" stipulates that the migration limit of bisphenol S in food simulants is 0.05mg / kg. [0004] Bisphenol F, also known as 4,4 dihydroxydiphe...
