Model 3300 ELSD is designed for use with High Performance Liquid Chromatography (HPLC) systems to analyze any sample compound that has sufficiently lower volatility than the mobile phase. Some of its possible application areas include carbohydrates, pharmaceuticals, lipids, triglycerides, underivatized fatty and amino acids, polymers, surfactants, nutraceuticals, and combinatorial libraries. Evaporative light scattering detection eliminates common problems associated with other HPLC detectors. Refractive Index (RI) detectors can be complicated by solvent front interferences, baseline instability, and gradient incompatibility. RI detectors can also have a less sensitive response than ELSD. Low-wavelength UV can suffer baseline drift with steep gradients and also requires that the analyte contains a chromophore. ELSD does not have these limitations. It can achieve stable baselines with multisolvent gradients for improved resolution and faster separations. Also, since ELSD response does not depend on the sample’s optical characteristics, the sample does not require a chromophore or fluorophore for detection.

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.
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.
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.

The Type 70 Ti, rated for 70 000 rpm, is a fixed angle rotor designed to centrifuge up to eight tubes at a 23-degree angle to the axis of rotation. Used in Beckman Coulter class H, R, and S preparative ultracentrifuges, the rotor develops centrifugal forces sufficient for applications including pelleting of small particles, and purification of viruses and subcellular organelles using sucrose gradients. Up to 312 mL of sample and gradient can be centrifuged per run. The rotor is made of titanium and is finished with black polyurethane paint. The aluminum lid and handle are anodized for corrosion resistance. The handle is interchangeable with the Type 70.1 Ti rotor handle but no others. O-rings made of Buna N rubber in the lid and handle maintain atmospheric pressure inside the rotor during centrifugation, if they are properly lubricated. The lid is a patented design that seats on the rotor body so that centrifugal force aids sealing. Four small holes in the lid provide a temporary vent, preventing pressure build-up and extrusion of the large lid O-ring in the event of leakage. Because of the weight of the rotor, drive pins are not required in the rotor drive hub cavity.
