Particle size and zeta potential analyzer for physical properties of fluids

我们建议购买Nanobrook Omni颗粒大小和Zeta电位分析仪，该分析仪可以同时执行动态光散射(DLS)和相分析光散射(PALS)，以高准确度和精密度确定颗粒尺寸和Zeta电位。具有这些能力的乐器在卡尔顿大学是没有的。该仪器将提供经济、实时的分析，消除更复杂的颗粒表征分析程序(例如，Cryo-SEM(扫描电子显微镜))。Nanobrook Omni颗粒大小和Zeta电位分析仪对乳液、纳米材料、多肽和寡核苷酸进行了表征，包括食品、药品、生物和环境样品中颗粒的疏水/亲水特性。卡尔顿大学自然科学与工程系(NSE)的四个学术单元(化学、生物、生物化学和工程)的成员迫切需要这种仪器。这一最先进的仪器将使食品科学、化学毒理学、膜生物化学和生物系统、环境化学和聚合物工程研究中的高级表面化学研究成为可能。拟议的工具将在短期内促进40名高素质人员(HQP)的培训，并在未来五年内培训约450名HQP，支持NSE赞助的跨学科研究。

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.
