Yes, Agilent PDA will also give you a spectrum; the limitation of Agilent's PDA, at least in Chemstation, is that you can't subsequently build from the collected spectra a chromatogram at any chosen wavelength - you only get chromatograms at the fixed wavelengths you asked for in advance - frustrating, but that's how it is.

Thank you for the info, I'm working with a Dionex PDA, and hence using Chromeleon. Used to work with Chemstation in the past, but never found any instructional resource for macros.
