  • 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.
