Shimadzu Spd20a User Manual

Purge the flow cell with degassed Methanol at a high flow rate (e.g., 2–3 mL/min). Replace lamp if noise persists. Temperature fluctuations or contaminated cell.

The detector utilizes a deuterium lamp for UV light and an optional tungsten lamp (for AV model) for visible light. The optical path includes diffraction gratings and mirrors that must be kept clean to maintain sensitivity.

Advanced optical coatings, superior noise suppression, and temperature-controlled flow cells for minimal baseline drift. shimadzu spd20a user manual
