PDA Settings - Interpolate & Blocking Filter (below 210 nm)

Hi there,

Can anyone tell me what these settings specifically do? I've tried the PDA manuals, Empower help and even Google but still can't find either a suitable explanation.

  • Hi Rob,

    When the Use UV blocking filter (below 210 nm) check box in the inlet method (MassLynx) or instrument method (Empowe) of the ACQUITY PDA is selected, a UV blocking filter moves into the light beam path to remove light with wavelengths shorter than 210 nm from entering the flow cell.

    This feature may be beneficial for solvents with a high UV cutoff. The user manual includes a table for UV cutoffs for common solvents.
