) solution, followed by a thorough flush with water until the pH returns to neutral. Never use hydrochloric acid. 5. Troubleshooting Common Issues Potential Cause Recommended Action Air bubble trapped in the flow cell.

Improved optical system reduces noise and drift. Wide Wavelength Range: Typically with optional tungsten lamp).

Place the unit on a flat, stable benchtop away from direct sunlight, air conditioner drafts, and heavy vibrational machinery. shimadzu spd20a user manual

The unit uses advanced, high-stability mirrors and filters designed for longevity, which the manual describes for proper calibration. 3. Operation and Method Development

Check that the wavelength is correct and the lamp is functioning. ) solution, followed by a thorough flush with

When setting up your SPD-20A, the manual lists three non-negotiable steps:

: The "AV" version allows both deuterium (D2) and tungsten (W) lamps to be lit at once, enabling high-sensitivity detection across both UV and visible light ranges Documentation & Maintenance Resources Place the unit on a flat, stable benchtop

Accesses validation and parameter customization menus.

Routine maintenance is critical to ensure a low noise level (typically AU) and baseline stability. UV-VIS detector / Photodiode Array Detector - Downloads

Immediately clean any leaks to avoid damaging the instrument's electronic components. Conclusion

Proper physical setup prevents baseline artifacts and communication errors with your chromatography data software (CDS), such as LabSolutions, LCsolution, or Empower. Fluidic Connections
