Workflow
Perform Prep Procedure
1-2 hoursFollow the established methodology for prep scale purification. Execute each substep with care, using calibrated instruments where needed. Follow chromatography standards throughout.
Record and Analyze Results
1 hourSystematically record all measurements and observations. Use appropriate units and notation. Cross-reference readings with expected ranges for chromatography.
Review Quality and Document Findings
45 minCompare collected data against reference standards. Identify any anomalies or areas needing repeat measurement. Create a complete record with all findings and next steps.

Prep Scale Purification StandardStandard
Industry standards and proven methods for prep scale purification in chromatography. Follow established protocols and verify against known benchmarks.
Key RelationshipFormula
Always verify unit consistency before applying any formula. Convert between metric and imperial systems as needed.
Prep Scale Purification BenchmarksTable
Key parameters and target values for quality assurance.
| Parameter | Target | Notes |
|---|---|---|
| Quality | Meet spec | Verify twice |
| Safety | PPE worn | Stop if unsure |
| Documentation | Complete log | Photo if needed |
Calibrate First
Uncalibrated instruments produce unusable data — verify zero and span before each session.
Contamination Control
Clean workspace between samples to prevent cross-contamination.
Chemical Hazards
Review SDS for all chemicals before use — know spill response procedures.
Safety Notes
- Organic solvents are flammable — no open flames in the lab.
- Wear safety goggles when handling pressurized HPLC systems.
