The 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.
ADDITIONAL INFORMATION
PDA-100 features include:
• Deuterium and tungsten lamps ensure low baseline noise, high signal intensity, and applications flexibility in the wavelength range from 190 nm to 800 nm.
• A 1024-element photodiode array optimizes spectral resolution.
• A built-in holmium oxide filter verifies wavelength calibration accuracy.
• Front panel LEDs indicate detector status at a glance. • Four analog outputs support data collection on alternate data collection systems.
