Usage and Care Guidelines
Installation Guidelines
- Inspect the cuvette - Before installation, examine the cuvette for any defects, cracks, or contamination on optical surfaces.
- Handle with care - Always wear powder-free gloves when handling the cuvette to prevent fingerprints and contamination on optical surfaces.
- Connect tubing - Use appropriate fittings with the stainless steel tube connectors. Tighten connections finger-tight plus 1/4 turn with a wrench to prevent overtightening.
- Avoid mechanical stress - Ensure tubing is properly supported to prevent stress on the cuvette connections.
- Flow orientation - Note the correct flow direction indicated on the cuvette housing and maintain consistent flow direction.
Performance Optimization
-
Flow rate control
- Maintain consistent flow rates to ensure stable baseline and signal response. Optimal flow rates typically range from 0.5-2 mL/min. -
Bubble prevention
- Degas mobile phases and samples to prevent air bubbles that can cause signal noise and baseline disturbances. -
Temperature stability
- Maintain stable temperature conditions to prevent thermal expansion effects on optical alignment. -
Baseline verification
- Periodically verify baseline stability with pure solvent to detect potential contamination or degradation issues.
Maintenance and Cleaning
- Regular flushing - After each use, flush the cuvette with appropriate solvent followed by clean, filtered water to prevent buildup of residues.
- Optical surface cleaning - For external optical surfaces, use lens-grade tissues with spectroscopic-grade solvents (ethanol or acetone) using a gentle wiping motion.
- Stubborn deposits - For persistent deposits, flow a solution of 5% laboratory-grade detergent followed by thorough rinsing with filtered water.
- Chemical compatibility - Avoid hydrofluoric acid (HF) and strong hot alkaline solutions, which can attack quartz surfaces.
- Storage - Store the clean, dry cuvette in a dust-free container at room temperature. Protect optical surfaces with lens tissue.
Troubleshooting Common Issues
-
Leakage at connections:
Check for proper fitting installation, replace damaged ferrules, and ensure connections are properly tightened without overtightening. -
Increased baseline noise:
Inspect for bubbles in the flow path, check for optical surface contamination, and verify stable flow conditions. -
Reduced sensitivity:
Examine optical surfaces for contamination, check for detector lamp stability, and verify proper optical alignment. -
Back pressure increase:
Look for potential blockages in the flow path, inspect inlet/outlet for particulate accumulation, and clean as needed.
