13 Questions You Should Ask When Buying Sample Prep Products

  1. What is your sample matrix?
  2. What volume of sample do you need to extract?
  3. What are your target analyte(s)?
  4. What are your sample clean-up goals (high recovery vs. clean-up vs. speed)?
  5. What sample preparation format is best for your work (i.e., disks or cartridges)?
  6. What is your mode of analysis (LC/UV, LC/MS/MS, GC/FID, GC/MS, etc.)?
  7. How quickly can the system perform exhaustive extractions?
  8. Can the extraction system operate unattended overnight?
  9. Does the system change solvents and perform rinses automatically between samples?
  10. What methods does the extraction system comply with? (i.e., U.S. EPA, ISO etc.)
  11. How does solvent consumption compare to other systems?
  12. Can the system handle solid and semisolid samples, or are multiple systems needed?
  13. Can the solvent be reclaimed?
