Abstract

A simple and highly sensitive method for the determination of caffeine in energy beverages was developed and validated. Sample preparation utilizing solid-phase extraction (SPE) was simple and reliable. Separation by isocratic ultra-high performance liquid chromatography (UPLC) with a reversed-phase C₁₈ column was performed within 6 min. The use of SPE with UPLC coupled with electrospray ionization-multiple tandem mass spectrometry detection (ESI-MSⁿ) was accurate, reproducible, and validated for the determination of caffeine in energy drink matrices. The limit of quantification for caffeine was approximately 2.1 ng mL^-1. The intra-day and inter-day precisions were less than 4%, and the accuracy of the measurements was between 85.1% and 93.2%. Results for caffeine concentrations in eighteen beverages were compared to the values on the labels. This paper describes the first use of the UPLC-ESI-ion trap MSⁿ technique for quality-control purposes of caffeine present in energy drinks.
