Gerstel Presents Automated Disposable Pipette Extraction (DPX)

Disposable Pipette Extraction (DPX) is a fast and efficient SPE technique used for a wide range of applications such as drugs of abuse and therapeutic drug monitoring. Only 200 - 250 μL of sample is needed to reach the required limits of detection using a fully automated process.

The extraction step is performed in 30 - 60 seconds and the complete process including elution and rinse steps takes 3 - 6 minutes depending on the application. Additionally, automated DPX is performed during the GC or LC run of the preceding sample ensuring maximum throughput and best possible GC/MS or LC/MS system utilization. Elution requires only a small amount of solvent, which means that DPX effectively provides a concentration step. For many applications, such as pesticides in fruit and vegetables, solvent evaporation is not required.
