To get a better understanding of the SPD-20A, here are some key features and specifications:
| Interval | Action | |----------|--------| | Daily | Check baseline noise, log lamp hours | | Weekly | Wash cell with 50% methanol (0.5 mL/min, 30 min) | | Monthly | Run wavelength calibration | | Every 2000h | Replace D2 lamp (Shimadzu 228-34016-02) | | As needed | Clean flow cell (sonicate in 1M HNO₃ if contaminated) | shimadzu spd20a user manual better
The manual warns against high pressure in the flow cell. However, it often understates the effectiveness of passive cleaning . To get a better understanding of the SPD-20A,
: To minimize baseline drift caused by ambient temperature changes, the detector uses a temperature-controlled flow cell. 2. Operational Best Practices Lamp Management : To check lamp life, press the "function" button on the front panel until "lamp hour" appears. : Used for UV range (190–700 nm).
