Accurate particle size zeta potential analyzer ideal for characterizing nanoparticles.
Featuring an enhancement to traditional DLS, the Nanotrac Wave II employs Reference Beating, which amplifies the signal back to the photodector, producing unparalleled accuracy for measuring particle size, zeta potential, molecular weight, and concentration of colloidal systems.
The Nanotrac Wave II provides users with superior particle analysis capability by taking advantage of an enhanced optical signal, innovative probe technology, and advanced algorithms. Whether your material is ppm or near finished product, the Wave II obtains fast, sensitive, and precise measurements of materials ranging from sub-nanometer to several microns.
The Nanotrac Wave II is a measurement system for direct automatic measurement of the electrophoretic movability and the Brownian motion as well as the thereof resulting zeta potential and particle size.
Microtrac is a pioneer of particle analysis technology and has been developing DLS systems for over 30 years. The Nanotrac Wave II is the newest generation of sub-micron particle size and zeta potential analyzers. The innovative design of the Nanotrac Wave II offers faster measurements with reliable technology, particle size measuring to below 0.8 nm, higher precision and accuracy, all of this combined in a compact Dynamic Light Scattering Analyzer without moving optical components. The extensive software package (license-free) calculates the analysis data in accordance with ISO 13321 and approved according to CFR21 Part 11.)
The measurement principle of the Nanotrac series is based on Dynamic Light Scattering (DLS) in a 180° Heterodyne – backscatter arrangement. In this setup a part of the laser beam is added to the scattered light. This works like an optical enhancement of the scattered light. Particle sizes range from 0.8 to 6.5 microns.
Reference Beating increases the optical signal anywhere from 100 to 1,000,000 times compared to traditional DLS. The increased optical signal enables users to accurately measure single and multi-mode distributions across the widest concentration range in the market. Dubbed appropriately, the Microtrac Way, check out this short presentation to learn more about our proprietary technology.
Setup in laser scatter light (180°) for concentrated and diluted particle dispersions. Software for analysis of the electrophoretic mobility, the zeta potential (according to Smoluchowski) as well as the particle size distribution through direct analysis of the Brownian motion.
