Shimadzu Spd20a User Manual Better |best|
This report provides a structured overview of the Shimadzu SPD-20A/20AV UV-VIS Detector, synthesized from official user documentation, aiming to improve accessibility and understanding for users of the Prominence (LC-20) and Nexera systems. 1. Overview and Key Specifications
: The SPD-20A includes a temperature-controlled flow cell as standard to minimize baseline drift caused by room temperature fluctuations. Wavelength Programming shimadzu spd20a user manual better
- Faster instrument commissioning and less downtime due to clearer setup and preventative guidance.
- Improved data quality from better baseline/noise management and method examples.
- Reduced service costs by enabling lab technicians to resolve common issues safely.
- Easier onboarding of new staff via quick-start materials and visual tutorials.
- Standardized practices across labs through downloadable SOP templates.
Ghost Peaks: Replace mobile phase bottles and clean the column. 6. Enhanced Technical Details This report provides a structured overview of the
5. Troubleshooting Without Calling Service
| Symptom | Most likely cause | Fix |
|---------|------------------|-----|
| Noisy baseline (low frequency) | Air bubbles in cell | Purge cell at 3 mL/min with degassed mobile phase. |
| Spikes (random, sharp) | Dust or crystals in flow cell | Clean cell as above. |
| Gradual baseline drift | Detector not warm | Wait 60 min. Check lab temp stability. |
| No signal at all | Lamp off or failed | Check lamp icon on display. Go to [FUNC] → [1] LAMP. |
| High pressure in cell only | Clogged outlet tube | Disconnect outlet; if pressure drops, replace outlet capillary. |
| Wavelength inaccurate | Lamp aging or misalignment | Run WAVE CHECK (use holmium oxide filter, optional). | Faster instrument commissioning and less downtime due to
Modes: Supports single-wavelength, dual-wavelength, and spectra scanning (when flow is stopped).
Flow Cell Cleaning: If you notice a drifting baseline or ghost peaks, your flow cell may be contaminated. Flush it with a suitable solvent (like 2-propanol) if you've been using salts or buffers.
Lamps are the most common consumable. To avoid premature failure SHIMADZU CORPORATION Track Usage : Press the "function" button on the front panel until lamp hours are displayed The Rockefeller University Replacement Cycles
