If you observe rising noise or ghost peaks, the cell may need cleaning or inspection.

The user manual outlines specific procedures for setting up the detector for daily operation via HPLC software (such as LabSolutions or EZStart). A. Power-On and Initial Check Turn on the main power switches for all HPLC components. Launch the chromatography software (e.g., EZStart 7.4).

Before starting an analysis, it is essential to set the baseline to zero. Pressing the function key will set the current absorbance reading to 0.0 AU for the selected channel(s). This step should be performed when the baseline is stable and the mobile phase is flowing through the 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.
