This standard is proposed and managed by the National Certification and Accreditation Administration. This standard was drafted by the Guangdong Entry-Exit Inspection and Quarantine Bureau. The main drafters of this standard. Yu Cuiping, Zhou Minghui, Xiao Qian, Chen Qiang, Liu Yingfeng, Zheng Jianguo, Xiao Dahui. This standard is the first industry standard for entry-exit inspection and quarantine. Method for detecting quaternary acetaldehyde in import and export Gas chromatography1 ScopeThis standard specifies the gas chromatographic detection method for the content of metaldehyde in the inlet and outlet of Minda. This standard is applicable to the dextran aldehyde in 6% granules prepared by extrusion and granulation of tetraacetaldehyde original drug and filler. Determination.2 Method summaryAfter the sample was ground, the tetraacetaldehyde in the sample was ultrasonically extracted with chloroform. After centrifugation and filtration through a microporous membrane, the filtrate is injected. Detected in a gas chromatograph equipped with a hydrogen flame detector and quantified by internal standard method.3 reagents and materialsThe reagents were of analytical grade unless otherwise stated. 3.1 Trichloromethane. 3.2 Tetraacetaldehyde standard. purity ≥ 98.0%. 3.3 Internal standard. dimethyl phthalate, chromatographically pure.4 Instruments and equipment4.1 Gas Chromatograph. with a hydrogen flame detector. 4.2 Ultrasonic cleaning machine. 4.3 High speed centrifuge. 5000r/min. 4.4 Filter membrane. PTFE, 0.45 μm. 4.5 Microsampler. 10 μL.5 Analysis steps5.1 Sample preparation The Milda sample was crushed through a mortar and passed through a 40-mesh sieve. Weigh the sample about 0.5g (accurate to 0.0002g) and place it in 25mL In a stoppered Erlenmeyer flask, about 0.03 g (accurate to 0.0002 g) of dimethyl phthalate was added. Pipette 10.0mL of chloroform to the conical flask in. After ultrasonic extraction for 20 min, it was centrifuged. The supernatant was taken, filtered through a microporous membrane, and the filtrate was subjected to gas chromatography. 5.2 Standard solution preparation Approximately 0.03 g (accurate to 0.0002 g) of the metaldehyde product standard was weighed and placed in a 10 mL volumetric flask. Add about 0.03g (accurate to 0.0002 g) Dimethyl phthalate, dissolved in chloroform, and made up to volume. Shake well. 5.3 Gas chromatographic conditions a) SPBTM-5 capillary column (15m × 530μm × 3.00μm) or equivalent; b) inlet temperature. 100 ° C; c) detector temperature. 180 ° C; d) Column temperature program. initial temperature 70 ° C, hold 1 min, 5 ° C/min rise to 100 ° C, 10 ° C/min rise to 180 ° C, keep 10min; ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of SN/T 1787-2006_English be delivered?Answer: Upon your order, we will start to translate SN/T 1787-2006_English as soon as possible, and keep you informed of the progress.
