Disposable Pipette Extraction DPX
Step by step
Sample is drawn into the pipette tip for direct contact with the solid phase sorbent. There is no contact between the sample and the syringe used to aspirate the sample and therefore no risk of cross contamination.
Air is drawn into the pipette tip from below through the frit. Turbulent air bubble mixing creates a suspension of sorbent in the sample, ensuring optimal contact, highly efficient extraction, and high recovery.
The extracted sample is discharged, typically after 30 seconds. If needed, the sorbent can be washed to remove unwanted residue.
Extracted analytes are eluted using a suitable solvent, which is added from above for most effi cient elution. The eluate is collected in a vial for subsequent sample introduction to LC/MS or GC/MS.
