说明

General description

SUPELCOSIL ABZ+Plus 色谱柱可提供高去活特性和独特的选择性。经失活处理的硅胶颗粒粒径均一，确保其具有高柱效和低背压。经过键合和封尾后，ABZ+Plus 键合相有效的屏蔽了残余硅羟基，阻止了残余硅羟基与大多数化合物间的相互作用，无论分析物基团的特性如何均可获得对称的峰形。该键合相也允许在流动相中使用低离子强度的缓冲溶液，无需添加离子抑制剂。ABZ+Plus 让您可以使用简单的流动相来进行最困难的化合物分析，无论酸、强碱性化合物还是两性离子均可轻松胜任。
按照美国药典 (USP) 适用于 L60

Features and Benefits

•对极性、非极性和带电荷分析物均具有很高的柱效
•对具有反应性的化合物也可获得对称性良好的峰形
•对极性和带电荷的化合物具有独特的选择性

Quantitative determination of the beta-blocker labetalol in pharmaceuticals and human urine by high-performance liquid chromatography with amperometric detection.

C Ceniceros et al.

Journal of chromatography. B, Biomedical sciences and applications, 705(1), 97-103 (1998-03-14)

A rapid and simple high-performance liquid chromatographic (HPLC) method with amperometric detection has been developed for the quantitation of labetalol in urine. The chromatography was performed at 30 degrees C using a reversed-phase column with a base deactivated silica stationary

Determination of 8-epi PGF(2alpha) concentrations as a biomarker of oxidative stress using triple-stage liquid chromatography/tandem mass spectrometry.

Nasser E Bastani et al.

Rapid communications in mass spectrometry : RCM, 23(18), 2885-2890 (2009-08-12)

F2-isoprostanes are a family of prostaglandin F2-like compounds that are formed by free-radical-catalyzed peroxidation of arachidonic acid. Several F2-isoprostanes, but in particular 8-epi PGF(2alpha), are widely used as oxidative stress biomarkers. An analytical method based on liquid chromatography with negative

Determination of 20 underivatized proteinic amino acids by ion-pairing chromatography and pneumatically assisted electrospray mass spectrometry.

P Chaimbault et al.

Journal of chromatography. A, 855(1), 191-202 (1999-10-09)

A qualitative determination of 20 underivatized proteinic amino acids by LC-MS is reported. The need for chromatographic separation before mass spectrometry determination is demonstrated based on the study of several amino acid pairs which have some similar characteristics. Two suitable
