Tengzhou Zhongkepu Priority Recommended Product - Mosquito Repellent DEET Content Analysis Gas Chromatography
【Product IntroductionanophelifugeDEETThe chemical name isN. N-diethyl-3-methylbenzamide
DEET not only has strong and long-lasting mosquito repellent effects that are not affected by geography, but also is non-toxic, odorless, and safe to use. It also has a broad-spectrum characteristic and has a repellent effect on other pest species. Tengzhou Zhongkepu used DEET content analysis of mosquito repellent and determined the mosquito repellent by gas chromatography with dibutyl phthalate as the internal standardDEETThe content can be separated and determined within 10 minutes under the selected chromatographic conditions, with fast speed and good separation effect, and the determination results are satisfactory
