產(chǎn)品簡介

反相保留；適用于多組分、極性分布寬的樣品分析

詳細介紹

XSelect HSS T3柱能顯著增強對極性分子的反相保留能力與 99%水相兼容，且鍵合相抗流失能力強，可用于LC/MS分析“平衡柱"，對強疏水性分析物保留減弱，pH 穩(wěn)定范圍 2一8，適用于多組分、極性分布寬的樣品分析。

沃特世很清楚顆粒基質(zhì)在色譜選擇性和保留特性方面所起的作用：沒有單種顆?；w能夠滿足所有的色譜分析挑戰(zhàn)。另外，鍵合到不同基體上的同一配體也能產(chǎn)生各種不同的色譜結(jié)果。高強度硅膠 [HSS] 技術(shù)的開發(fā)專門用于與疏水性更強的 BEH 和 CSH 顆粒的色譜性能相互補。與含亞乙基橋的 BEH 和 CSH 顆粒相比，HSS 顆粒更強的硅醇基活性（99% 硅膠）可提供明顯的色譜優(yōu)勢，包括增加極性化合物的保留和顯著的選擇性差異。另外，正如名字所示，HSS 顆粒被設(shè)計和合成用于可承受 UPLC 壓力所需的機械強度

液相色譜-線性離子阱-靜電場軌道阱高分辨質(zhì)譜測定蜂膠中9種黃酮類物質(zhì)

本文利用線性離子阱-靜電場軌道阱(LTQ-Orbitrap)高分辨質(zhì)譜,配合全自動篩選應(yīng)用軟件ToxID可以對大量數(shù)據(jù)進行高通量分析的特點,建立了蜂膠中楊梅酮、喬松素、芹菜素、苛因、素、高良姜素、槲皮素、蘆丁、桑黃素9種黃酮類物質(zhì)的快速篩選和確證方法。樣品使用無水乙醇提取,采用Waters xselect HSS T3色譜柱(100×3.0mm,3.5μm),以乙腈-0.1%乙酸溶液為流動相,FT正離子掃描模式進行質(zhì)譜檢測,外標(biāo)法定量。結(jié)果表明,該方法對以上除楊梅酮外8種黃酮類化合物的線性范圍為0.5~50μg/mL,楊梅酮的線性范圍為1.0~50μg/mL,相關(guān)系數(shù)(r)均大于0.99。在625mg/kg、1 250mg/kg、2 500mg/kg 3個添加水平的回收率為78.7%~93.3%,相對標(biāo)準(zhǔn)偏差為7.10%~12.65%。
