Bioanalysis Zone a vital tool for bioanalysts

Image
by Cameron Low, Digital Editor for Bioanalysis Zone As a reader of the Microextraction Tech blog, and as someone who possesses a keen interest in the bioanalytical field, it is a great honor to be able to write this post on Bioanalysis Zone . Bioanalysis Zone is brought to you by Future Science Group, the publishers of Bioanalysis, a prominent fortnightly, peer-reviewed journal. The site features the latest news relevant to those working within the bioanalytical field; articles from Bioanalysis; exclusive interviews and commentaries from opinion leaders working within academia and the pharmaceutical industry; exclusive webinars with a variety of experts; and a business directory. We also provide a forum for the community to discuss recent developments and pose any questions related to this fast moving field. Fabio Garofolo, Associate Editor of Bioanalysis, commented, “I truly believe that since bioanalytical science, techniques and regulations are evolving so fast, it is i...

Rotating Disk Sorptive Extraction

Image
by Prof. Dr. Pablo Richter, Department of Inorganic and Analytical Chemistry, Faculty of Chemical and Pharmaceutical Sciences, University of Chile. The modern trends in analytical chemistry promote efficiency and green technology in sample preparation. In this context, our research team developed a new technique in 2009 that is capable of extracting pollutants from liquid samples on a rotating PTFE disk with one surface coated with an extraction phase [1]. The disk has embedded a miniature magnetic rod, which allows rotation. We have termed this procedure rotating-disk sorptive extraction (RDSE). RDSE is currently available in two configurations. In the classic version (Figure 1), the extraction phase is a polymeric film adhered to one side of the PTFE disk (configuration 1). In this configuration, polydimethylsiloxane (PDMS), nylon and octadecyl (C18) have been used as the sorptive material for the extraction of low-polarity analytes (Log Kow between 3 and 7) [1-12].
