Regular maintenance is key to the SPD-20A's longevity and performance. The service manual provides detailed procedures:

is designed to deliver industry-leading performance. It features a temperature-controlled cell, reducing refractive index changes caused by fluctuations in room temperature, which directly translates to a stable baseline and higher sensitivity. 190 to 700 nm (Standard SPD-20A). Noise Level: 0.5 x 10-510 to the negative 5 power AU (highly sensitive). Linearity: 2.5 AU. shimadzu spd20a user manual

The appropriate lamp must be selected for the measurement wavelength:

If you observe rising noise or ghost peaks, the cell may need cleaning or inspection. This public link is valid for 7 days

Toggles through operational parameters (wavelength, absorbance, lamp status).

Perform a wavelength calibration after replacement. Flow Cell Maintenance Can’t copy the link right now

Verify the wavelength setting, ensure the flow cell is not contaminated, and check if the lamp is lit. 4. SPD-20A vs. SPD-M20A (Photodiode Array)

Insert the new lamp, ensuring no fingerprints are left on the lamp glass.
