Abstract

The invention discloses a method for measuring dimethyl fumarate in a product by gas chromatography-mass spectrometry. The method comprises the following steps of: pretreating a dimethyl fumarate product to be detected by using an ultrasonic extraction method; setting the temperature of a sample injection port of a gas chromatography-mass spectrometer to be 240-280 DEG C, a flow rate to be 0.8-1.5 ml / min and the temperature of a port to be 280-300 DEG C, and selecting a weak polar column for a chromatographic column; enabling a sample to enter the chromatographic column through the sample injection port, and carrying out temperature programming on the temperature of the chromatographic column to separate the components of the sample by the chromatographic column; and enabling the components separated by the chromatographic column to enter a mass spectrometric detection part through the port of the gas chromatography-mass spectrometer, wherein an electron impact ion source is adopted as the ion source of the mass spectrometric detection. The method for measuring the dimethyl fumarate in the product by the gas chromatography-mass spectrometry has low detection limit, good detection effect, little consumption of analysis solvent and low detection cost.

Description

technical field

[0001] The invention relates to a detection method for dimethyl fumarate in products, in particular to a method for detecting dimethyl fumarate in products by gas chromatography-mass spectrometry. Background technique

[0002] Dimethyl Fumarate (Dimethyl Fumarate, DMF for short) is a white powdery crystal with a slight ester fragrance. It can effectively inhibit and kill more than 30 kinds of molds, yeasts and bacteria. Therefore, it is widely used in industry, agriculture, food and other industries. For example, DMF is used for anti-mold of building materials, wood products and plastic products. It is also used in food and catering industry, medicinal materials, tobacco, textiles, film, leather and its products, paper. Anti-mildew, anti-moth and disinfection of coatings, dyes, adhesives, etc.

[0003] However, studies have shown that DMF can enter the human body through the digestive tract, respiratory tract and skin, causing skin allergies, irritating the ...
