產(chǎn)品簡介

氟苯基柱、對(duì)位置異構(gòu)體、鹵代化合物和極性化合物具有優(yōu)異選擇性。

詳細(xì)介紹

ACQUITY UPLC CSH氟苯基色譜柱對(duì)位置異構(gòu)體、鹵代化合物和極性化合物具有優(yōu)異選擇性。部分原因在于多種保留機(jī)理的綜合效果，包括偶極-偶極作用、氫鍵作用、芳香性(π-π)作用和疏水作用。但由于帶電表面顆粒[CSH]的化學(xué)特性，與傳統(tǒng)PFP鍵合固定相相比，CSH氟苯基色譜柱可增強(qiáng)對(duì)酸性化合物的保留。

液相色譜-串聯(lián)質(zhì)譜法快速測定食品中的

采用超高壓液相色譜-電噴霧串聯(lián)四極桿質(zhì)譜建立了醬油、醋和可樂中的的快速檢測技術(shù),為相關(guān)中毒事件的樣本分析提供方法學(xué)依據(jù)。方法食品樣本用水稀釋后經(jīng)C18固相萃取小柱凈化, Waters ACQUITY UPLC CSH Fluoro-Phenyl色譜柱分離,以0.1%乙酸水和乙腈溶液為流動(dòng)相梯度洗脫,最后用液相色譜-串聯(lián)四極桿質(zhì)譜儀在負(fù)離子MRM模式下測定。結(jié)果目標(biāo)化合物在2.0~1000μg/L范圍內(nèi)線性良好,相關(guān)系數(shù)r2大于0.99。以醬油、醋和可樂為加標(biāo)基質(zhì),在50、100、200μg/kg三個(gè)加標(biāo)水平下的平均回收率為82.4%~107.1%,相對(duì)標(biāo)準(zhǔn)偏差小于20%,方法的檢出限為10μg/kg,定量限為25μg/kg。結(jié)論該方法操作快速簡單、靈敏度和重現(xiàn)性較好,成功用于兩起中毒事件的樣品檢測。
