New Findings Reported from National University Describe Advances in Capillary Electrophoresis

May 20, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- A new study on Capillary Electrophoresis is now available. According to news reporting originating in Santa Fe, Argentina, by NewsRx journalists, research stated, "This paper presents the development of a capillary electrophoresis method with diode array detector coupled to multivariate curve resolution-alternating least squares (MCR-ALS) to conduct the resolution and quantitation of a mixture of six quinolones in the presence of several unexpected components. Overlapping of time profiles between analytes and water matrix interferences were mathematically solved by data modeling with the well-known MCR-ALS algorithm."

The news reporters obtained a quote from the research from National University, "With the aim of overcoming the drawback originated by two compounds with similar spectra, a special strategy was implemented to model the complete electropherogram instead of dividing the data in the region as usually performed in previous works. The method was first applied to quantitate analytes in standard mixtures which were randomly prepared in ultrapure water. Then, tap water samples spiked with several interferences were analyzed."

According to the news reporters, the research concluded: "Recoveries between 76.7 and 125 % and limits of detection between 5 and 18 mu g L-1 were achieved."
