Intuitive Operation
ACQUITY QDa is as intuitive as an optical detector, with the robustness to handle all of your analyses. Working in harmony with your chromatography, it is pre-optimized to work with your samples, without the sample-specific or user adjustments typical of traditional mass spectrometers. For the first time, any analytical scientist can consistently generate the highest quality mass spectral data, routinely without the need for any special training or expertise thus eliminating any need to contract out and wait for results from specialist analytical service laboratories.
More information from every sample
With ACQUITY QDa Detector, you can minimize the risk of unexpected coelutions or components and you can confirm trace components with certainty because of the analytical confidence that mass detection brings. Enhance the analytical value and productivity of each analysis, eliminating the need to run all the additional assays or time-consuming alternative techniques.
Working in synergy with optical detection, you can significantly reduce the chance that a sample component will go undetected.
Effortless integration
The ACQUITY QDa Detector is compatible with all Waters ACQUITY UPLC, ACQUITY UPC2, Alliance HPLC, and purification LC and SFC systems. The ACQUITY QDa Mass Detector is complementary to your current Waters optical detectors including ACQUITY UPLC PDA, TUV, or FLR, or ACQUITY UPC2 PDA optical detectors.
The mass spectral information combines seamlessly into the same workflow, routinely giving you more complete characterization of your separation.
Process, interpret, visualize, and compare the most complex data, and turn it into meaningful information quickly and simply. The ACQUITY QDa Detector is fully compatible with Empower Software, our industry-leading chromatography data software platform.
With integrated optical and mass detector data processing workflows, you can also interrogate mass spectral data in the same way and same workflow as you do PDA data. The ACQUITY QDa Detector is also fully compatible with MassLynx Software and its suite of Application Managers.
Resolving complexity
Whether your focus is on advancing healthcare, protecting the environment, safeguarding our food and water supplies, or making new materials, the ACQUITY QDa Detector dramatically improves the capability of your existing analytical or purification system and is your simplest route to reliable, versatile mass detection.
