This standard applies to the test of 4,6-dinitro-o-cresol residue in apples and pears.2 sampling and sample preparation2.1 Inspection lot No more than 1500 pieces for an inspection lot. Goods in the same inspection lot should have the same characteristics, such as. packaging, marking, origin, specifications and grades. 2.2 Number of samples See Table 1. Table 1 Sample quantity Minimum number of batches 1~25 1 26~100 5 101～250 10 251~1500 15 2.3 Sampling method The number of samples according to 2.2 is randomly selected and opened one by one. Take at least 500g of each piece as the original sample, the total amount of the original sample shall not be Less than 2kg. After the seal, mark the mark and send it to the laboratory in time. 2.4 Sample preparation The original sample was taken out by 1 kg, and the edible portion was taken out, mashed evenly by a tissue masher, and divided into two parts, and placed in a clean container. As a sample, seal and mark the mark. 2.5 Sample storage The sample was stored at -5 ° C or less in the dark. During the sampling and sample preparation process, the sample must be protected from contamination or residue content. Variety.3 Determination method3.1 Method summary The 4,6-dinitro-o-cresol residue in the fruit sample was extracted with methylene chloride, blown to dryness and dissolved in acetonitrile, using N-(tert-butyl dimethyl Base silicon)-N-methyltrifluoroacetamide (MTBSTFA) was derivatized and determined by gas chromatography-mass spectrometry and quantified by external standard method. 3.2 Reagent materials All reagents were of analytical grade and water was deionized water unless otherwise stated. 3.2.1 Dichloromethane. excellent grade. 3.2.2 Acetonitrile. GC pesticide residue grade. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of SN/T 1734-2006_English be delivered?Answer: Upon your order, we will start to translate SN/T 1734-2006_English as soon as possible, and keep you informed of the progress.
