Malachite green and crystal violet in aquatic products and Rapid determination of metabolites1 ScopeThis standard specifies the residual color of malachite green and its metabolites in the aquatic products, leuco malachite green, crystal violet and its metabolites. Rapid determination of high performance liquid chromatography, liquid chromatography-tandem mass spectrometry. This standard applies to freshwater products and their products in malachite green and its metabolites, leuco malachite green, crystal violet and its metabolites. Determination of the amount of crystal violet residue. 1) The malachite green and crystal violet rapid detection pretreatment kit is produced by the China Inspection and Quarantine Science Research Institute and developed by Beijing Luqiao Commercial Inspection New Technology Co., Ltd. The product name of the product. This information is given in order to facilitate the users of this standard, rather than the recognition of this product by the standard administration.2 liquid chromatography2.1 Principle The residual malachite green, crystal violet and its metabolites in the sample are tested with the malachite green and crystal violet rapid detection pretreatment kit. The agent is extracted and concentrated, and then detected by liquid chromatography, and quantified by external standard method. 2.2 Reagents and materials All reagents were of analytical grade and water was double distilled water unless otherwise stated. 2.2.1 Acetonitrile. chromatographically pure. 2.2.2 Anhydrous sodium acetate. 2.2.3 Glacial acetic acid. chromatographically pure. 2.2.4 Isopropanol. 2.2.5 p-toluenesulfonic acid. 2.2.6 Acetate buffer. Weigh 4.950g of anhydrous sodium acetate and 0.950g of p-toluenesulfonic acid, dissolve in 950mL of water, use ice B The acid was adjusted to pH 4.5 and finally made up to 1000 mL with water. 2.2.7 Standard products. malachite green, leuco malachite green, crystal violet, leuco crystal purple purity greater than 98%. 2.2.8 Standard stock solution. accurately weigh 10mg of malachite green, leuco malachite green, crystal violet and leuco crystal violet, respectively, with acetonitrile It was placed in a 100 mL volumetric flask and formulated into a standard stock solution of 100 μg/mL. 2.2.9 Mixed standard solution. Dilute standard stock solution with mobile phase to prepare malachite green, leuco malachite green, crystal violet, leuco crystal The purple color was a mixed standard solution of 10 μg/mL. 0 ° C ~ 4 ° C protected from light. 2.2.10 Malachite green, crystal violet rapid detection pretreatment kit 1). 2.3 Instruments and equipment 2.3.1 High performance liquid chromatograph. equipped with UV-visible variable wavelength detector; the detection wavelength time program is controllable. 2.3.2 Homogenizer. 2.3.3 Rotary evaporator. 2.3.4 Centrifuge. 4000r/min, 8000r/min. 2.3.5 Oscillator. 2.3.6 Ultrasonic water bath. 2.3.7 Teflon centrifuge tube. 2.5mL, 50mL, with stopper. 2.3.8 Microporous membrane. 0.45 μm. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of SN/T 1768-2006_English be delivered?Answer: Upon your order, we will start to translate SN/T 1768-2006_English as soon as possible, and keep you informed of the progress.
