實(shí)驗(yàn)背景
吸毒者體內(nèi)的毒品成分或代謝物會(huì)在毛發(fā)生長(zhǎng)的過(guò)程中用于組織成分的合成,所以通過(guò)鑒定毛發(fā)的成分,可以快速判定疑犯是否有吸毒行為。
實(shí)驗(yàn)?zāi)康模貉心ッl(fā)樣品,檢測(cè)其毒品及其代謝物成分。
實(shí)驗(yàn)原理
毛發(fā)成分有多種提取方法,其中研磨提取最為高效準(zhǔn)確。通過(guò)將毛發(fā)研磨至粉末狀,可以大大增加毛發(fā)的表面積,并充分破壞其角質(zhì)蛋白,使溶劑能深入到毛發(fā)內(nèi)部的毛發(fā)髓質(zhì)層和皮質(zhì)層進(jìn)行充分的溶解萃取,再對(duì)萃取溶液檢測(cè)是否含有毒品成分,即可快速完成鑒定。
實(shí)驗(yàn)步驟:需了解具體步驟,請(qǐng)致電廠(chǎng)家
