Usage Guide of UV Quartz Cuvette for Powder Fluorescence Analysis
Sample Preparation and Loading
- Ensure powder samples are dry and homogeneous before loading
- Use non-scratching tools (plastic or PTFE spatulas) when transferring samples
- Fill cuvettes consistently to ensure reproducible measurements
- For sealed models, ensure caps are tightened appropriately but not over-tightened
Cleaning and Maintenance
- Clean optical windows with lint-free lens tissue and spectroscopic-grade solvents
- Avoid abrasive cleaners that may scratch optical surfaces
- Ultrasonic cleaning in dilute laboratory detergent is effective for thorough cleaning
- Rinse thoroughly with deionized water and allow to air dry or use filtered compressed air
Storage and Handling
- Store in original protective packaging or in dust-free containers
- Avoid touching optical windows with bare fingers; use gloves when handling
- Protect from mechanical shock and vibration during storage and transport
- Keep inventory records for tracking usage and replacement scheduling
Best Practices for Measurement

FAQ
Q: What makes UV quartz cuvettes better than glass for powder fluorescence analysis?
A: UV quartz cuvettes offer superior UV transmittance (down to 200nm) compared to standard glass (limited to ~350nm). This is critical for fluorescence measurements where excitation wavelengths often fall in the UV range. Additionally, high-purity quartz provides minimal background fluorescence, better thermal stability, and superior chemical resistance, ensuring more accurate measurements for powder samples.
Q: How do I ensure consistent powder packing for reproducible measurements?
A: For reproducible measurements, use a consistent sample preparation protocol:
(1) Ensure uniform particle size through sieving or grinding,
(2) Use a consistent filling method such as gentle tapping or a standardized packing tool,
(3) Maintain the same sample mass for each measurement,
(4) Consider using a sample press for very fine powders,
(5) Document your packing procedure for future reference.
Our cuvettes with flat optical windows help minimize variability in path length.
Q: Can your UV quartz cuvettes be used with corrosive or reactive powder samples?
A: Yes, our quartz cuvettes exhibit excellent chemical resistance to most acids, bases, and organic solvents, making them suitable for a wide range of reactive powder samples. The only significant exception is hydrofluoric acid (HF), which can etch quartz. For highly alkaline samples (pH >12), we recommend limited exposure times. For specialized applications involving extreme chemical environments, please consult with our technical team for material compatibility assessment.
Q: What is the temperature limit for UV quartz cuvettes during fluorescence measurements?
A: TOQUARTZ® standard UV quartz cuvettes can operate continuously at temperatures up to 600°C without dimensional changes or optical property degradation. For sealed models with PTFE components, the maximum temperature is limited to 260°C (PTFE’s maximum service temperature). For applications requiring higher temperatures (up to 1100°C), we offer specialized high-temperature quartz grades with appropriate design modifications to manage thermal expansion.
Q: How should I clean UV quartz cuvettes between different powder samples?
A: For thorough cleaning between samples:
(1) Remove powder residue using compressed air or gentle brushing,
(2) Rinse with an appropriate solvent (ethanol, acetone, or water depending on sample solubility),
(3) For persistent residues, use an ultrasonic bath with dilute laboratory detergent,
(4) Rinse thoroughly with deionized water,
(5) Dry with filtered compressed air or in a dust-free environment,
(6) Inspect optical windows for cleanliness before reuse. Avoid abrasive materials that could scratch the optical surfaces.
