Introduction

Clean solvents

Clean solvents provide these benefits:
• Reproducible results
• Operation with minimal instrument maintenance
A dirty solvent can cause these conditions:
• Baseline noise and drift
• Blockage of the solvent filters with particulate matter
To avoid chemical hazards, always observe safe
