1 • Introduction 1.1 Product Overview The Dionex PDA-100 Photodiode Array Detector (P/N 064532) is an optical detector capable of measuring the absorbance spectrum from 190 to 800 nm. A deuterium lamp optimizes the UV range (190 to 380 nm) and a tungsten lamp optimizes the visible range (380 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 analyses that do not require spectral data and it conserves disk space. Key features of the PDA-100 include: • The deuterium and tungsten lamps ensure low baseline noise, high signal intensity, and applications flexibility in the wavelength range from 190 to 800 nm. • The 1024-element photodiode array optimizes spectral resolution. • The built-in holmium oxide filter verifies wavelength calibration accuracy. • Five flow cells are available for standard, semi-micro, and semi-preparative applications. • The front panel LEDs indicate detector status at a glance. • Four analog outputs support data collection on alternate data collection systems. The PDA-100 is controlled remotely by a computer running the Chromeleon® Chromatography Management System. The detector communicates with the computer through USB (Universal Serial Bus). To take full advantage of the capabilities of the PDA-100, order Chromeleon with the 3D Data Acquisition license. This license is required in order to perform: • 3D data presentation and spectral analysis (real-time or post-run) • Peak purity analysis with selectable criteria Doc. 031898-03 3/06 1
