If sensitivity decreases or noise increases, flush the cell with appropriate solvents (e.g., IPA or mobile phase).
The OEM manual is excellent, but treat it as a reference, not a novel. Keep a printed copy near the detector, highlight the time-programming and error code pages, and you’ll solve 90% of SPD-20A issues faster. shimadzu spd20a user manual better
The SPD-20A is a UV-VIS detector optimized for high-sensitivity, high-speed analysis (UFLC). If sensitivity decreases or noise increases, flush the
, recognized for its industry-leading noise levels and exceptional baseline stability. Key Performance Features Ultra-High Sensitivity : Achieves a noise level of just If sensitivity decreases or noise increases
nm wavelength range and the "Dual Wavelength" mode, which allows simultaneous monitoring of two different wavelengths—a major efficiency boost for complex analyses.
