Description

The detector is a full-featured, time-programmable, photodiode array (PDA) detector capable of scanning the ultraviolet-visible wavelength range from 190 to 800 nm. You can acquire data across the entire spectral range (with an effective resolution of 1.2 nm) at a rate of 0.5 to 80 Hz with 20-bit digital conversion.

The PDA detector is a benchtop unit for inclusion in the Accela liquid chromatography system. You control the detector through an Ethernet link to a data system computer that has the Xcalibur or ChromQuest data system installed. The detector consists of a dual-light source, an optical bench, a photodiode array, a low voltage power supply, several printed circuit boards (PCBs), and four status light-emitting diodes (LEDs).
