This comprehensive guide serves as an practical manual for operators, covering installation, daily usage, routine maintenance, and troubleshooting. 1. Technical Overview and Specifications
The SPD-20A is a standard UV-Vis absorbance detector, while its sibling model, the SPD-20AV, adds visible light capabilities via a halogen lamp. Understanding its core specifications helps maximize its performance in your assays. Key Specifications Deuterium ( D2cap D sub 2 ) lamp (plus a Halogen lamp for the SPD-20AV variant). shimadzu spd20a user manual
The "Shimadzu SPD-20A user manual" includes a comprehensive section for diagnosing errors.
| Symptom | Probable Cause | Corrective Action | |---------|----------------|--------------------| | High baseline noise | Air bubbles in cell | Flush with degassed mobile phase or remove cell and rinse. | | Negative peaks | Sample absorbs less than mobile phase at set wavelength | Change wavelength or check mobile phase UV cutoff. | | Lamp fails to ignite | Lamp expired or power supply issue | Check lamp hours; replace D2 lamp. | | No signal at high sensitivity | Flow cell window dirty | Clean cell with 1M HNO₃, then water, then methanol. | | Wavelength error | Stepper motor failure or filter stuck | Run Wavelength Calibration from service menu (qualified personnel only). |
