The Dionex PDA-100 Photodiode Array Detector is an optical detector capable of measuring the absorbance spectrum from 190 nm to 800 nm. A deuterium lamp optimizes the UV range (190 nm to 380 nm) and a tungsten lamp optimizes the visible range (380 nm to 800 nm).
When using the PDA-100, up to five single wavelengths (2D chromatograms) can be collected without being required to collect 3D data. Collecting individual wavelengths instead of the spectra offers two advantages: it eliminates the need to perform extractions for runs that do not require spectral data and it conserves disk space.
This refurbished Dionex PDA-100 Photodiode Array Detector is in great condition. It has been tested at SpectraLab Scientific.
A 90 day warranty is included.
We are seasoned professionals in this area and we would be happy to have you speak with one of our experts here at SpectraLab.
Thanks for looking and we look forward to hearing from you!
