Traditional Nanoparticle Tracking Analysis (NTA) often fails to accurately characterize polydisperse samples like extracellular vesicles, fine bubbles, viruses, and engineered nanoparticles. The ViewSizer™ 3000 overcomes this limitation by employing an advanced Multi-energy NTA approach—specifically, Multispectral NTA—to capture comprehensive, detailed particle data across the entire size distribution. The ViewSizer 3000 uses simultaneous measurement with three lasers at different power levels, ensuring every particle is accurately tracked, regardless of its scattering intensity. This results in the most complete size and concentration information for samples from 10 nm to 15 microns. Key Advantages of the ViewSizer 3000 Multi-energy NTA for Comprehensive Data: Using different power levels for each laser color, the system automatically corrects for particle size effects on light scattering. Data from a lower power laser is used when a particle signal is too bright, and data from a higher power laser is used when scattering is too weak, guaranteeing accurate results across a wide size range in a single measurement. Guaranteed Accuracy and Compliance: Fully compliant with ISO 19430: 2024 for reliable, traceable particle size and concentration determination. Zero Cross-Contamination: The easy-to-remove sample cell can be fully disassembled for rapid and thorough cleaning, eliminating the risk of cross-contamination and ensuring high data integrity—a critical factor for core facilities and high-throughput labs. Wide Dynamic Range: Measures sample concentrations from 105 to 109 particles/mL and particle sizes from 10 nm to 15 µm.
