The ACQUITY UPLC® Photodiode Array (PDA) Detector allows your laboratory to detect and quantify lower concentrations of sample analytes and compare spectra across wavelengths and broad concentration ranges. It has data rates of up to 80 Hz, noise specifications of ±3 µAU, and an extended linear range. With the PDA detector, you can fulfill multiple UPLC®/MS detection strategy requirements for the identification of components that are difficult to resolve by conventional HPLC-based methods. Features: Quantitates trace impurities at levels to 0.004% with low signal-to-noise ratios, high optical and digital resolution, and library matching Achieves UPLC/PDA separations with flexible parameter control and sampling rates for accurate, reproducible integration Offers efficient light transmission for maximum sensitivity Provides simultaneous 2D and 3D operation in either Empower™ or MassLynx™ Software Wavelengths of 190 to 500 nm and up to 2.0 AU without compromising linearity 1.3% deviation at 2.0 AU 5.0% deviation at 2.8 AU
