190 to 700 nm (SPD-20A) or 190 to 900 nm (SPD-20AV). Sensitivity: Noise level of AU (Absorbance Units). Linearity: Wide linearity up to 2.5 AU.

: This occurs when the absorbance exceeds the detector's limits ( >2.5is greater than 2.5

Ghost peaks, loss of signal intensity, or constant high absorbance offsets indicate a contaminated flow cell window. shimadzu spd20a user manual better

The SPD-20A features an automatic internal holmium oxide filter to check wavelength accuracy. Run this diagnostic from the utility menu to verify the instrument aligns within the ±1plus or minus 1 nm specification. To help tailor this guide further, please let me know:

The flow cell is temperature-controlled to reduce baseline drift. 190 to 700 nm (SPD-20A) or 190 to 900 nm (SPD-20AV)

The SPD-20A utilizes a deuterium (D2) lamp to provide a wavelength range of .

From the front panel: [FUNC] → [DIAG] → [LOG] . This shows last 10 errors (e.g., lamp ignition fail, energy low). Clear it after maintenance. It's far more useful than random guessing. : This occurs when the absorbance exceeds the
