Restart the system. If it fails diagnostics again, perform a manual wavelength calibration or replace the lamp. Ruptured flow cell window or loose fitting.

The manual warns never to turn on the deuterium lamp without the flow cell installed—you will permanently damage the optical system. Align the locating pins, insert the new lamp,

While most users control the SPD-20A via software, the front-panel keypad provides immediate access to critical diagnostics and manual monitoring. Front Panel Layout

The Shimadzu SPD-20A is a high-performance, dual-wavelength UV-Vis absorbance detector designed for high-performance liquid chromatography (HPLC). It is part of Shimadzu’s Prominence series and is known for its low noise level (< ±0.25×10⁻⁵ AU), high sensitivity, and excellent baseline stability. This paper outlines key hardware features, front panel operation, maintenance, and troubleshooting. Up to 2

A contaminated flow cell results in high baseline noise, ghost peaks, or a reduction in light energy.

Is your detector operated or controlled by software (e.g., LabSolutions, Empower)?
