The core of operating the SPD-20A lies in the configuration of analytical parameters, typically managed via the keypad on the front panel or through Shimadzu’s LabSolutions software. The operator must define the Wavelength ($\lambda$) . Selecting the correct wavelength is the most impactful decision in method development; it should correspond to the absorption maximum ($\lambda_max$) of the target compound.
