Shimadzu Spd20a User Manual: !new!

The SPD-20A’s front panel is menu-driven with an LCD display and function keys.

Replace the lamp when it fails to ignite or when the energy levels drop below acceptable thresholds.

The front panel allows for direct control without PC software configuration.

Connect the OUTLET tubing from the upper port of the flow cell to the waste container or a subsequent detector (e.g., mass spectrometer or refractive index detector).

The manual divides maintenance into three categories. Ignoring these voids your warranty. shimadzu spd20a user manual

| Error Message | Probable Cause | Recommended Action | | :--- | :--- | :--- | | | D2 lamp is defective, lamp not connected, or PCB (circuit board) defect. | Check lamp connection. Replace D2 lamp. If error persists, contact Shimadsu service. | | "ERR W LAMP" | Tungsten lamp (SPD-20AV) is defective or not connected. | Check connection. Replace W lamp. | | "CHECK NO GOOD" | Wavelength calibration failed: bubble in cell, wrong sample, or defective Hg lamp. | Purge flow cell. Clean cell with appropriate solvent. Perform WAVE CALIB again. | | Instrument Failure | Communication timeout or noise on the communication line. | Check instrument method's "LC Stop Time". Ensure physical cable connections are secure. | | No Communication | Incorrect IP address setting (networked systems) or physical connection fault. | Verify the SPD's IP address settings. Ensure the Ethernet (or other) cable is properly connected. |

The "Shimadzu SPD-20A user manual" includes a comprehensive section for diagnosing errors.

Allow the detector to warm up for at least 30-60 minutes to ensure baseline stability. The SPD-20A’s front panel is menu-driven with an

: When the deuterium (D2) lamp is on, "D2" is shown on the detector's display. You can activate the lamp through the software method or the front panel keypad. Method Parameters : Wavelengths and other settings can be edited in the panel within your chromatography software.

Warm-up: The D2 lamp requires at least 30 minutes to stabilize before starting an analysis. Operating before the lamp is warm can result in baseline drift. Operating Procedures

The Shimadzu SPD-20A user manual details several core functions designed to maximize performance and ensure accurate data acquisition. A. Initial Setup and Start-up

The Shimadzu SPD-20A UV-VIS detector user manual outlines procedures for achieving high-sensitivity HPLC analysis within a 190 to 700 nm range, featuring a temperature-controlled flow cell and deuterium lamp management. The documentation emphasizes essential maintenance, including lamp hours, self-diagnostics, and proper cooling requirements. Access the full instruction manual on Scribd .

One of the key advantages of the SPD-20A is its ability to monitor two wavelengths simultaneously.

The flow cell is crucial for reducing refractive index changes caused by temperature fluctuations. The manual details how to properly connect and check this cell for leaks.
