ACQUITY QDa Mass Detector ACQUITY QDa Detector is a mass detector built around the needs of analytical scientists for chromatographic analysis. Robust, reliable and requiring no sample adjustments, it integrates with your current LC, ACQUITY UPLC, UPC2 and purification systems.
2489 UV/Visible (UV/Vis) Detector for Purification and Modular LC Systems A versatile, dual-wavelength absorbance detector that offers simplicity for routine UV-based applications and high sensitivity for low-level impurity analysis.
2998 Photodiode Array (PDA) Detector for Purification and Modular LC Systems Add spectral conformation to your absorbance detection methods while still maintaining high sensitivity and a wide linear dynamic range.
2424 Evaporative Light Scattering (ELS) Detector for Purification and Modular LC Systems A complementary detection technique for semi- and non-volatile compounds with little or no UV absorbance. Compatible with both isocratic and gradient methods.
2414 Refractive Index (RI) Detector for Modular LC Systems Offers high sensitivity, stability, and reproducibility, making this detector the ideal solution for the isocratic analysis of components with limited or no UV absorption.
2475 Fluorescence (FLR) Detector for Modular LC Systems Delivers unsurpassed sensitivity and selectivity for quantifying low concentrations of target compounds, whether naturally fluorescent or derivatized with a fluorescent tag.
