The TurboVap LV Evaporation System concentrates organic solvent extracts using steam and nitrogen. A timer allows for unattended operation. This set-up is ideal for residue analysis (“going to dryness”) or analyses that can be taken to a low volume. The patented vortex shearing action provides rinsing as the sample concentrates to maximize recoveries. The internal rack in the TurboVap LV is 24 positions and can be removed to use on a benchtop. A removable “plate” allows the user to convert the rack from 40 mL to 60 mL vials and vice versa. This rack can also be used for the new graduated, stemmed 40 mL Dionex vials.
Cyclosporine is an immunosuppressant used in organ transplants to overcome rejection. Following the transplant of a heart, liver, kidney or lung, a patient must be regularly tested for the rest of their lives. Blood testing intervals vary from 1 month to 6 months and this rapid reference method is ideal for batch tests with the advantage of no metabolite interfer-ence which is always found in immunological methods.
The removal of interferences and sample concentration are essential steps in trace level detection of pesticides, sheep dips, herbicides and PCBs in river water, wastewaters and trade effluents. The following methods were developed by the Environment Agency National Laboratory Service facility at Nottingham using the Biotage RapidTrace for automated solid phase extraction and the TurboVap II for evaporation. The procedures are UKAS accredited and can reach detection limits of 0.001 ug/Litre for some compounds.
EPA methods 8260 & 8270 cover the analysis of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans in ground & surface waters. This also now includes 1,4-dioxane and PCBs. This application note will focus on the automated SPE of the sample rather than the detection which usually involves GCMS or LCMS. NB The columns and reagents used for soils and sediment analysis differ to ground water extraction.
With the widespread clinical use of antidepressant drugs comes the need to accurately measure therapeutic lev-els to determine proper dosage, as well as check for toxic levels and patient compliance. More and more laboratories are shifting their therapeutic drug monitor-ing from liquid extraction to solid phase extraction. A large clinical laboratory has automated the process of extracting these drugs from serum using the RapidTrace SPE Workstation.
