Concentrating a suite of semi-volatile compounds from EPA method 625 using the new Biotage TurboVap II
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 theEuropean 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.

New vs. old TurboVap LV
This modern design features many new enhancements, including a well-lit glass tank for much greater visibility, removable/replaceable nozzles on the lid, on- the- fly nozzle adjustment, easily exchangeable manifolds to extend functionality, programmable evaporation flow gradients, easy access drain port and user friendly touch screen interface. The system can be vented from the bench or placed in a fume hood. Because the footprint is noticeably smaller on the modern unit, less space is required.

The new TurboVap LV Multi Rack series for Mini Vials is highly adaptable for changing needs
Due to the four height adjustment screws and the 11/12 mm top plate, the multi rack for mini vials is capable of accommodating different tubes and vials both in terms of length and diameter. In order to use the TurboVap LV Multi Rack with your TurboVap LV system, you need to adjust the Multi Rack and set it up for the tube/vial type that you wish to use.
