Waters Acquity QDa Detector

The Waters Acquity QDa Detector brings high-quality, mass spectral data to chromatographic separations. Designed as a synergistic component of a chromatographic system, the mass detector is compatible with Waters Acquity UltraPerformance LC (UPLC), Acquity UltraPerformance Convergence Chromatography (UPC2), Alliance high-performance liquid chromatography (HPLC) and Waters supercritical fluid chromatography (SFC) and LC-based purification systems.

The product is designed for analytical scientists who need mass spectral data without the complexity of a mass spectrometer. With on/off simplicity, the unit fully automates sample analysis and eliminates sample-specific adjustments for certainty in sample results, from user to user and system to system. Robust and reliable enough for routine use, the device generates the high-quality mass spectral data expected of a single quadrupole mass spectrometer in a mass detector no bigger than a familiar photodiode array (PDA) detector. 

The product complements optical detection, such as the PDA detector, by confirming the identity of compounds with mass spectral information. Additionally, it extends the limits of sample detection for a chromatographic separation by quantifying compounds having no UV response or that are present at levels not detectable and quantifiable by optical detection. By simplifying laboratory workflows the unit increases productivity, eliminating the need to run additional assays or turn to time-consuming alternative techniques in order to establish with certainty the levels and identity of specific sample compounds.

The product is suitable for pharmaceutical discovery and development, chemical materials and food laboratories engaged in method development, sample profiling, synthetic chemistry and purification.
