Troubleshooting Sample Preparation
This webcast will address some of the most common problems encountered in the lab when carrying out sample preparation using filtration, liquid/liquid extraction (LLE), and solid phase extraction (SPE). We will provide troubleshooting strategies as well as tips and tricks to avoid problems in the first place.
Topics covered:
- Essential sample preparation troubleshooting strategies
- Filtration
- Selecting the correct filter membrane
- Avoiding unwanted analyte/membrane interactions
- Matching filter dimensions to sample volume
- Liquid/liquid extraction (LLE)
- Improving quantitation
- Treating emulsions
- Acid/base/neutral extractions - where’s the analyte?
- Solid phase extraction (SPE)
- Dealing with the most common SPE problems: recovery, reproducibility & cleanliness
