| Description | The DAWN™ instrument is an advanced detector for precise characterization of proteins, polymers, and nanoparticles including viral vectors, lipid nanoparticles and vesicles. Using multi-angle static light scattering (MALS) and optional dynamic light scattering (DLS), DAWN analyzes molar massThe DAWN™ instrument is an advanced detector for precise characterization of proteins, polymers, and nanoparticles including viral vectors, lipid nanoparticles and vesicles. Using multi-angle static light scattering (MALS) and optional dynamic light scattering (DLS), DAWN analyzes molar mass, size, conformation, particle concentration, conjugation (e.g. glycoproteins) or encapsulation (e.g. AAV capsid content). It stands out with exceptional sensitivity and the widest range of molecular weight, size, and concentration of any MALS instrument, paired with a broad selection of configurations and optional modules for enhanced capabilities.
The DAWN is most often used in conjunction with gel permeation chromatography (GPC-MALS), size exclusion chromatography (SEC-MALS) or an EclipseTM, field-flow fractionation instrument (FFF-MALS) and may also be used with ion-exchange chromatography or reverse-phase chromatography. The instrument includes a high-resolution, touch-screen front panel to display data graphs, system health and instrument diagnostics and is accompanied by ASTRA™, the most versatile software package available for analysis of online multi-angle and dynamic light scattering....

Its ability to provide a consistent response for molecules that lack strong UV absorbance makes it especially valuable when working with complex formulations, excipient mixtures, and process-related impurities. With robust performance and straightforward operation, the CAD supports confident decision-making from early analytical exploration through late-stage process control.
Key Features and Benefits:- Universal detection performance for compounds that are traditionally difficult to monitor with UV alone, including lipids, sugars, and surfactants.
- High sensitivity and low detection limits to strengthen impurity tracking and enhance characterization of challenging components.
- Broad dynamic range enabling simultaneous measurement of major constituents and trace-level species.
- Complementary to UV and mass detection, adding depth and flexibility to method development strategies.
- Fully compatible with Waters UPLC, UHPLC, and HPLC systems, with Empower™ Software that supports efficient, compliant data analysis across biopharma workflows.

Key benefits include low band broadening, < 4 µL, to maintain the resolution of very narrow UHPLC peaks. Its dRI measurement range is, - 4.7 x 10-3 to + 4.7 x 10-3 RIU (comparable to 25 mg/mL protein in PBS). The detector is highly sensitive, ± 1.5 x 10-9 RIU, across the entire measurement range. This detector measures solvent refractive index, required for MALS calculations at the same wavelength as the MALS detector, for maximum accuracy. The temperature range of 4°C - 65°C is appropriate for both proteins and polymers that require a range of temperatures. It also features a high-resolution, touch-screen front panel displays data graphs, system health indicators and instrument diagnostics.... Read More |
