C-2 Solvent Considerations
Introduction
Clean solvents
Clean solvents provide these benefits:
• Reproducible results
• Operation with minimal instrument maintenance
A dirty solvent can cause these issues:
• Baseline noise and drift
• Blockage of the solvent filters with particulate matter
Solvent quality
Use HPLC-grade solvents to ensure the best possible results. Filter solvents
through 0.45-µm filters before use. Solvents distilled in glass generally
maintain their purity from lot to lot; use them to ensure the best possible
results.
Preparation checklist
The following solvent preparation guidelines help to ensure stable baselines
and good resolution:
• Filter solvents with a 0.45-µm filter.
• Degas the solvent.
• Stir the solvent.
• Keep in a place free from drafts and shock.
Water
Use water only from a high-quality water purification system. If the water
system does not provide filtered water, filter it through a 0.45-µm membrane
filter before use.
