Shimadzu Spd20a User Manual ~upd~ May 2026

The Shimadzu SPD-20A is a high-sensitivity UV-VIS detector for the Prominence HPLC series, featuring a temperature-controlled flow cell to minimize baseline drift in the 190 to 700 nm range. Key features include dual-wavelength monitoring, 2.5 AU linearity, and automated wavelength scanning for improved analytical performance. Maintenance includes regular lamp energy monitoring and flow cell cleaning. For detailed operating instructions, refer to the Shimadzu manual .

• The SPD-20A connects via analog output (1 V/AU) to an integrator or digital (RS-232C / USB) using Shimadzu’s CBM-20A or LC-20AD pump’s built-in controller.
• For software control (LabSolutions or CLASS-VP):

  Software Connection

  : Open your control software (e.g., LabSolutions or EZStart). A beep confirms connection, and the Remote LED should light up. Lamp Activation : shimadzu spd20a user manual

  • Safety Compliance: The manual contains critical warnings about high-pressure flow cells, UV radiation, and electrical hazards.
  • Wavelength Calibration: Incorrect calibration ruins data. The manual provides the step-by-step procedure using holmium oxide or deuterium lamp lines.
  • Diagnostic Accuracy: Error codes like "ERR CELL" or "LAMP ERROR" are cryptic unless you consult the manual’s troubleshooting matrix.
