Samples were taken from the pieces. Mix all the samples taken, put them into a clean and dry sample bag, seal them, mark them, and deliver them in time. Laboratory. 2.4 Sample preparation The sample 3 was randomly selected from the extracted samples, and the debris, debris, and the like attached to the sample were removed. Weigh the quality of each pair of chopsticks The sealed sample bag is sealed and measured as a test sample. 2.5 Sample storage The sample was stored at room temperature. Samples should be protected from contamination or changes in residue levels during sampling and sample preparation.3 Determination method3.1 Method summary In the sample, thiabendazole, o-phenylphenol, biphenyl and imazalil were extracted with methanol, and the extract was filtered and detected with a diode array. The liquid chromatograph of the device or the ultraviolet detector is used for measurement, and the external standard method is used for quantification. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of SN/T 1623-2005_English be delivered?Answer: Upon your order, we will start to translate SN/T 1623-2005_English as soon as possible, and keep you informed of the progress.
