The Shimadzu SPD-20A is a cornerstone of the Prominence HPLC series, known for its exceptional sensitivity and reliability in UV-VIS detection. However, the standard Shimadzu SPD-20A instruction manual can sometimes feel more like a technical schematic than a practical field guide.

If that fails:

Remove the cell (two screws) and sonicate the cell body and quartz windows in isopropanol for 10 min. Reassemble with new gaskets (part #228-35146).
