Fast Separation of Seven Biocides Using an Agilent ZORBAX Rapid Resolution High Definition Eclipse Plus C18 1.8 μm Column

Abstract: An Agilent ZORBAX Rapid Resolution High Definition (RRHD) Eclipse Plus C18 1.8 μm column separated seven different biocides rapidly with high resolution. The data presented illustrate the capability of the short 50 mm, 1.8 μm column to maintain high resolution of complex samples at very fast flow rates and high pressures, up to 1020 bar. The high quality separation was maintained when the method run was reduced from 3 minutes to 0.7 minutes by increasing the flow rate from 1.0 mL/min to 1.7 mL/min. The Agilent 1290 Infinity LC System was used because the column pressure just exceeded 1000 bar at this high flow rate. Methylparaben, listed as an echinacea supplement ingredient, was easily identified and a hand sanitizer containing 2-phenoxyethanol and methylparaben were also easily and rapidly identified using the method.
