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