ACQUITY UPLC & ACQUITY Premier PDA eLambda Detectors
PDA detection for spectral exposure optimization
Getting accurate and complete spectral information to make better decisions about your analysis can be a challenge. The ACQUITY UPLC and ACQUITY Premier Photodiode Array (PDA) eλ Detectors enable a laboratory to detect and quantify lower concentrations of sample analytes as well as compare spectra across the ultraviolet and visible wavelengths, allowing analyses encompassing a broader concentration range.
The detectors meet multiple UPLC-MS detection strategy requirements and provide the ability to map low levels of compounds and determine trace impurity levels within a compound’s peak.
