Detection of Insecticides in Tea Shimadzu Glass Column
Detection of Insecticides in Tea Shimadzu Glass Column Details:
name: glass column
Specifications: 3mm (inner diameter) * 2m
Model: 1.5%OV-17/Chromosorb W (80-100 mesh)
Application: GB/T 5009.114-2003 Determination of Pesticide Residues in Rice
Suitable for various types of Shimadzu gas chromatographs GC2010, GC-2014
Insecticidal is a broad-spectrum insecticide. Insecticide is widely used in rice, leafy vegetables and other crops to co ntrol rice borers, leaf rollers, rice budworms, thrips, leafhoppers, rice planthoppers, cabbage caterpillars, diamo ndback moths, etc. It is moderately toxic to humans and animals .
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a method for the detection of ciprofloxacin in tea. Weigh the test sample, add hydrochloric acid solution, sonicate, filter, wash the residue with hydrochloric acid solution, and adjust the solution with sodium hydroxide solution pH to 8.5~9.0, add sodium sulfide solution, react in 70 ℃ water bath for 2.5h, take out and cool, add chloroform for extraction, separate layers, repeat the extraction twice, the combined extracts are dried over anhydrous sodium sulfate, spin-dried , dilute to 1.0 mL with methanol, and quantitatively analyze by GC-MS to obtain the co ntent of ciprofloxacin in tea leaves. It has the advantages of high sensitivity, good stability and simple operation.
