The Shimadzu SPD-20A operates on the principle of UV-Vis absorbance detection. The detector consists of a light source, a beam splitter, and a photodiode array. The light source emits a beam of light that passes through the flow cell, where the sample is detected. The beam splitter divides the light beam into two parts: one part passes through the sample, while the other part serves as a reference.
Like any analytical instrument, the Shimadzu SPD-20A may encounter issues during operation. Here are some common problems and troubleshooting tips: shimadzu spd20a user manual
Preventative maintenance extends the lifespan of the optical components and guarantees data integrity. Flow Cell Flushing Protocol
If your SPD-20A is connected via CBM-20A to LabSolutions, the software includes a "Module Help" menu. Click on the SPD-20A icon → "Manual" to open context-sensitive pages for error codes.
Before diving into operation, it is important to understand what the SPD-20A offers compared to its siblings (like the SPD-20A/20AV). Never use a wire to clean the cell
In the maintenance or VP menu, reset the lamp hour counter to zero to keep accurate tracking records. Cleaning and Flushing the Flow Cell
