First Standard?標(biāo)準(zhǔn)品助力!——【SCIEXLabs最新方案】2小時(shí)搞定水中176種有機(jī)污染物

近年來,環(huán)境水中的新型微量有機(jī)污染物——藥物和個(gè)人護(hù)理品(Pharmaceuticals and Personal Care Products, PPCPs)已引起公眾和學(xué)術(shù)界的廣泛關(guān)注,檢測分析環(huán)境水中PPCPs的挑戰(zhàn)在于存在水體中的PPCPs濃度非常低 (ng/L, ppt級(jí)別),且污染物種類來源廣泛;本文介紹了用SCIEX QTRAP®4500液相色譜串聯(lián)質(zhì)譜系統(tǒng)建立了一套環(huán)境水中176種PPCPs的篩查和定量分析方法,并獲得了非常好的結(jié)果。



環(huán)境水樣品的分析流程






1、176種有機(jī)污染物 (PPCPs和農(nóng)藥) 的種類

抗生素和激素:β-內(nèi)酰胺類(18),喹諾酮類(16),磺胺類(18), 大環(huán)內(nèi)酯類 (11), 四環(huán)素類 (13), 激素類 (14);

其它藥品和護(hù)理品: 精神類 (15), 糖尿病類 (6), β-Blocker (4), 哮喘、鎮(zhèn)咳 (5), 興奮劑 (4), 心血管類 (12),廣譜抗菌 (7), 解熱鎮(zhèn)痛 (6), 胃酸和抗凝劑 (3);

農(nóng)藥: 氨基甲酸酯類 (16), 苯氧羧酸類 (8)。


2. 樣品前處理——簡單、快速

水樣品量需50 mL,極大地降低了SPE 的上樣時(shí)間;采用3 mL,60 mg 的小體積SPE 柱,最后洗脫體積僅3 mL,大大降低了氮?dú)獯蹈上疵撘旱臅r(shí)間,整個(gè)樣品處理過程僅需2個(gè)小時(shí)左右。


3. LC-MS/MS方法分組少,分析時(shí)間短——高通量

質(zhì)譜采用電噴霧(ESI)正負(fù)離子化、MRM采集方式 ,同一液相色譜方法,LC-MS/MS分析時(shí)間為13.5 min。



圖1. 176種濃度為5 ng/mL的PPCPs標(biāo)準(zhǔn)品色譜圖。


4. LC-MS/MS方法靈敏度高,篩查和定量結(jié)果可靠。

1) 與美國EPA 16941方法相比,本方法具有更高的靈敏度。


2) 可快速篩查出環(huán)境水樣品中未知的有機(jī)污染物。

3)準(zhǔn)確定量環(huán)境水樣品中有機(jī)污染物的濃度。

表2. 某城市污水處理廠入口處污水中環(huán)丙沙星的濃度為23.02 ng/L。 


5. 該方法包括詳細(xì)且完善的實(shí)驗(yàn)操作流程,從樣品前處理,到LC-MS/MS方法,定量方法及結(jié)果報(bào)告模板,并經(jīng)實(shí)驗(yàn)內(nèi)與實(shí)驗(yàn)室間方法學(xué)驗(yàn)證,是真正“拿來即用”的LC-MS/MS方法,大大節(jié)省了方法開發(fā)的時(shí)間。



總結(jié)


本文建立了一套檢測環(huán)境水中176種PPCPs和農(nóng)藥污染物的篩查和定量LC-MS/MS方法,覆蓋有機(jī)污染物種類廣,樣品前處理快速、簡單,LC-MS/MS方法具有分析時(shí)間短,通量高,檢測靈敏度高等特點(diǎn),可快速篩查和定量環(huán)境水樣品中的未知有機(jī)污染物。該方法包括了詳細(xì)的實(shí)驗(yàn)操作流程,大大節(jié)省了方法開發(fā)時(shí)間,是真正“拿來即用”的LC-MS/MS方法。
