Particle size and zeta potential analyzer for physical properties of fluids

点击翻译按钮获取中文摘要

We are proposing to purchase a Nanobrook Omni particle size and zeta potential analyzer that performs simultaneous dynamic light scattering (DLS) and phase analysis light scattering (PALS) to determine particle size and zeta potential with high accuracy and precision. An instrument with these capabilities is not available at Carleton University. This instrument will provide an economical, real-time analysis, eliminating more complex analytical procedures for particle characterization (e.g., Cryo-SEM (Scanning Electron Microscopy)). The Nanobrook Omni particle size and zeta potential analyzer characterizes emulsions, nanomaterials, peptides and oligonucleotides, including hydrophobic/hydrophilic properties of particles in food, drug, biological and environmental samples. This instrument is urgently needed by members of four academic units (Chemistry, Biology, Biochemistry and Engineering) that span the Natural Sciences and Engineering (NSE) within Carleton University. The state-of-the-art instrument will enable advanced surface chemistry research in food science, chemical toxicology, membrane biochemistry and biological systems, environmental chemistry, and polymer engineering studies. The proposed instrument will facilitate training of 40 highly qualified personnel (HQPs) in the short-term and ~450 HQPs over the next five years, supporting interdisciplinary NSE-sponsored research.
