有機(jī)磷農(nóng)藥是20世紀(jì)30年代末問(wèn)世的第二代人工實(shí)驗(yàn)部分合成農(nóng)藥,具有廣譜、、品種多和殘毒期短等優(yōu)點(diǎn)。有機(jī)磷農(nóng)藥對(duì)生物體的毒性主要是抑制生物體內(nèi)膽堿脂酶的活性,使大量的乙酰膽堿在生物體內(nèi)蓄積,造成神經(jīng)傳導(dǎo)生理功能的紊亂。

浩瀚色譜（山東）應(yīng)用技術(shù)開(kāi)發(fā)有限公司采用自動(dòng)固相萃取法預(yù)處理,用氣相色譜-質(zhì)譜儀測(cè)定有機(jī)磷農(nóng)藥。低檢出限在0.10~0.30mg/L之間,水樣加標(biāo)回收率為75%~105%,樣品經(jīng)5次重復(fù)測(cè)定后相對(duì)標(biāo)準(zhǔn)偏差均小于6.0%。結(jié)果表明,該法具有簡(jiǎn)單、快速、準(zhǔn)確的特點(diǎn)。

Shimadzu 2014 Glass Column Determination of Malathion in Water

Details of Malathion in Water Determined by Shimadzu Glass Column in 2014:



Organophosphorus pesticides are the second generation of partially synthetic pesticides produced in the late 1930s. They have the advantages of broad spectrum, high efficiency, many varieties and short residual toxicity. The toxicity of organophosphorus pesticides to organisms is mainly to inhibit the activity of cholinesterase in organisms, so that a large amount of acetylcholine is accumulated in organisms, causing the disorder of nerve conduction physiological function.



Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. adopts automatic solid phase extraction for pretreatment and uses gas chromatography-mass spectrometer to determine organic phosphorus pesticides. The minimum detection limit is 0.10~0.30mg/L, the recovery rate of water sample is 75%~105%, and the relative standard deviation of the sample after five repeated determinations is less than 6.0%. The results show that the method is simple, fast and accurate.
