Introduction
There are a wide range of volatile and semi-volatile contaminants finding their way into both terrestrial bodies and water sources worldwide. In the United States (US), the contaminants are analyzed according to stipulated US-EPA methods. In the European Union (EU), a large number of these same compounds are tested according to the European Water Framework Directive. Though these analytes are approached differently from a regulatory perspective, it is clear that background monitoring occurs on a global basis. Initial extraction of these analytes depends on the matrix being analyzed and is often a multifaceted process, but ultimately analysts are presented with some form of extraction/organic solvent they must concentrate to achieve instrumental limits of quantification. Presented within this technical note are the results of such an evaporative process using the new Biotage TurboVap® II.
The new TurboVap® II is built on the solid foundations of reliability and performance that made it the market leader for solvent evaporation. The modern design incorporates many new customer driven features for easier use and expanded functionality. TurboVap II still utilizes the highly efficient patented gas vortex shearing technology, which is synonymous with the TurboVap brand. This modern design features many new enhancements, including a well-lit glass tank for much greater visibility of the samples, improved sensors with automatic end-point detection, user replaceable nozzles, easy access drain port, and a color, menu driven touchscreen for simple operation and monitoring. The system can be vented from the bench or placed in the fume hood. Because the footprint is noticeably smaller on this modern unit, less space is required.
