WebThe Raptor Biphenyl column worked very well for the 12 mycotoxins studied in the cited work, but for longer compound lists containing isobaric mycotoxins with similar structures, the Raptor FluoroPhenyl phase may be necessary to … WebFor example, when using a 100 mm x 2.1 mm ID column, one column volume is 0.2 mL. If we are running an isocratic method with a flow rate of 0.30 mL/min, then the column should be conditioned with at least 10 mL (50 volumes x 0.2 mL volume). The total conditioning time would be 33 min (10 mL ÷ 0.30 min/mL).

WebJun 9, 2010 · The 2-[(4-fluorophenyl)sulfonyl]ethoxy carbonyl (Fsec) group for protection of hydroxyl groups has been designed, synthesized, and evaluated. Fsec-Cl was readily prepared in 91% yield over three steps and subsequently used to protect 4-fluorobenzyl alcohol in high yield. The Fsec group was cleaved from the resulting model compound … WebRestek's FluoroPhenyl columns are also amenable to LC-MS because they are extremely reliable and efficient with acidic mobile phases.
