The Waters ACQUITY UPLC Photodiode Array (PDA) detector was developed specifically for the Waters ACQUITY UPLC system. With data transfer rates of up to 80 Hz and noise levels as low as 10 AU, the ACQUITY UPLC PDA detector offers a sensitivity unmatched by any other photodiode array detector on the market. In addition, the advanced software control enables flexible 2D and 3D use, which can be operated in either Empower or MassLynx software. Article. Specification. wavelength range. 190 to 500 nm.
