SUPELCOSIL ABZ+Plus columns offer both high deactivation and unique selectivity. Deactivated silica particles of very narrow particle size distribution ensure high efficiency with low back pressure. After bonding and endcapping reactions, the ABZ+Plus phase effectively shields unreacted silanol groups on the silica, preventing them from interacting with most analytes, and provides symmetric peaks regardless of an analyte′s functionality. The phase also allows you to use low ionic strength buffers without having to add an ion-suppressing modifier. ABZ+Plus enables you to use simple mobile phases when analyzing the most difficult compounds; acids, strongly basic compounds, and zwitterions. suitable for L60 per USP

Liquid chromatography with a column-switching technique was developed for simultaneous direct quantification of levofloxacin, gatifloxacin and moxifloxacin in human serum. Serum samples were injected on a LiChroCART 4-4 pre-column (PC) filled with a LiChrospher 100 RP-18, 5 microm where fluoroquinolones

A reversed-phase high-performance liquid chromatographic method with electrochemical detection has been developed for the determination of buspirone from human plasma. The separation was carried out by using a Supelcosil ABZ+ plus C18 reversed-phase column and 0.05 M potassium dihydrogenphosphate (pH
