Multi-Laser Nanoparticle Tracking Analysis (NTA)

Exosomes? Virus? Nanoparticle? Use multiple lasers for complete, detailed analysis of all the particles in your sample.

Exosomes, viruses, and nanoparticles all have wide size distributions which defeat traditional Nanoparticle Tracking Analysis (NTA) analyzers. The ViewSizer 3000 features simultaneous measurement with three lasers to collect the most accurate distribution and concentration information over a wide range of sizes within the same sample. Where the signal from a particle is too bright and saturates the detector from one laser, the software automatically uses data from a lower power laser to ensure the most accurate size and concentration information. On the other hand, when scattering from one laser is too weak for detection, the software uses data from a higher power laser to accurately track the particle.

Cross contamination is a concern in all analyses. Simplified cleaning means thorough cleaning. The easy-to-remove sample cells can be dissassembled for rapid, thorough cleaning, which leads to better data.

The ViewSizer 3000 uses the latest advances in nanoparticle tracking analysis (NTA) to accurately determine particle properties!

Size Measurement Range: 10 nm to 15 microns depending on sample

The ViewSizer determines particle size and size distribution details by multi-laser nanoparticle tracking analysis (NTA). Multiple lasers enable analysis of a broad range of sizes in the same sample.

Concentration Measurement Range: 5 x 106 to 2 x 108 particles/mL

NTA can be used to count particles in the measurement volume. A patented method corrects for the effect of particle size on effective measurement volume.

No cross-contamination

The sample cell can be completely removed and dissassembled for complete cleaning. Disassembly, cleaning, and reassembly is faster than rinsing a flow cell. Furthermore, multiple cells can be used for faster throughput or assigned to various groups in a shared (core) facility.
