System Overview and Initialization The SPD-20A is designed to measure the absorbance of ultraviolet and visible light by analytes as they elute from the HPLC column. Its dual-wavelength capability allows for the simultaneous monitoring of two distinct wavelengths, a critical feature for analyzing samples with multiple components that absorb at different frequencies.

Power Connection: Connect the power cable to a grounded outlet. Turn on the main switch located on the front panel. shimadzu spd20a user manual

Common "Drift" Culprit: If your baseline is drifting, it’s often dirty cell lenses rather than the lamp itself. You can dismantle the flow cell to clean or replace these lenses.
