Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. The standard proposed by China National Light Industry Council. This standard by the National Toy Standardization Technical Committee (SAC/TC253) centralized. This standard was drafted. Shenzhen Academy of Metrology and Quality Inspection, the Guangdong Entry-Exit Inspection and Quarantine Bureau Technology Center Toys Experiment Room, Shenzhen City, measuring Detection Co., Ltd., Jiangsu Skyray Instrument Co., Ltd., the national daily commodity quality supervision and inspection center, the Ningbo Entry Inspection and Quarantine Bureau of Light Industry Products Testing Center, Beijing Certification Center of Light. The main drafters of this standard. Yangwan Ying, Ling Ping, Huang Li Na, ants Le Chau, Chen Dewen, Ruan Jian Miao, Zhu Ping, Zheng Jianming, Yao Dongliang. Determination of toys dimethyl fumarate content Gas chromatography - mass spectrometry (GC-MS) method Warning --- personnel should use this standard regular laboratory work experience. This standard does not point out all possible security asked question. Users have the responsibility to take appropriate safety and health practices and to ensure compliance with the conditions relevant national regulations.

1 Scope

This standard specifies the toys in dimethyl fumarate content by gas chromatography - mass spectrometry detection methods. This standard applies to toys, leather products, textiles, wood and other materials in the residue of dimethyl fumarate and dimethyl fumarate desiccant Ester content. Other materials may refer to. Principle 2 Using ethyl acetate sample of dimethyl fumarate ultrasonic extraction, the extract was filtered and concentrated to volume by gas chromatography - mass spectrometry Spectrometer (GC-MS) was measured using selected ion qualitative and quantitative internal standard.

3 Reagents and materials

3.1 ethyl acetate, analytical grade. 3.2 Standard substance dimethyl fumarate (dimethylfumarate, referred to as DMF) (CASNo..624-49-7). mass fraction of not less than 99.0%. 3.3 Internal standard. malonate (dimethylmalonate, abbreviated DMM) (CASNo..108-59-8), the mass fraction of not less than 99%; or diethyl malonate (diethylmalonate, abbreviated DEM) (CASNo..105-53-3), mass fraction of not less than 99%. 3.4 DMF standard stock solution. accurately weighed 0.1g (accurate to 0.0001g) in DMF standard (3.2), with ethyl acetate (3.1) Constant volume to 100mL, formulated at a concentration of 1000mg/L of standard stock solution. 3.5 internal standard stock solution. accurately weighed 0.1g (accurate to 0.0001g) of DMM or DEM (3.3), with ethyl acetate (3.1) constant volume To 100mL, formulated as standard stock solution at a concentration of 1000mg/L of. Note 1. This standard selected two internal standard, can be used for quantitative detection in the actual testing, optionally one of the internal standard. Note 2. The standard and internal standard stock solution should be in the 0 ℃ ~ 4 ℃ refrigerator, valid for three months. 3.6 internal standard working solution. the internal standard stock solution (3.5) dilute the concentration of the internal standard preparation work between 0.05mg/L ~ 10.00mg/L of Solution. 3.7 standard working solution. DMF standard stock solution (3.4) diluted formulation at a concentration between 0.005mg/L ~ 5.00mg/L Rich Horse dimethyl standard working solution, the solution of the working internal standard working solution (3.6) in the preparation process, and make it to be and the concentration of the internal standard Test sample internal standard concentration close. Note. The internal standard working solution and standard solution should be stored at 0 ℃ ~ 4 ℃ in the period of one month. 3.8 neutral alumina SPE. 1000mg/6mL.
