Introduction: NS-90Z nano particle size and potential analyzer is a new product launched by adding zeta potential test function on the basis of NS-90 nano particle size analyzer. NS-90Z has superior particle size and potential analysis functions, which can meet the particle size and surface potential testing needs of the majority of nanomaterials, formulation development and production users. The instrument uses electrophoretic light scattering technology to measure zeta potential, dynamic light scattering technology to measure particle and molecular size, and static light scattering technology to measure the molecular weight of proteins and polymers. NS-90Z integrates M3-PALS phase analysis detection technology, and extensively uses high-quality optoelectronic components in the global supply chain, such as imported avalanche photodiode (APD) detectors and He-Ne gas lasers, plus precise internal temperature control Technology, airtight fiber optic path and advanced software algorithms ensure the high repeatability, accuracy and sensitivity of data, so that this model instrument can analyze samples with a wide range of particle size, concentration and potential. NS-90Z also supports SOP standard operation and intelligent evaluation of measurement data, which is convenient for users to use. Purpose: The NS-90Z Nanoparticle Size and Potential Analyzer is an extremely cost-effective nanoparticle characterization instrument. It is suitable for applications that require higher particle size measurement sensitivity or require the same results as the 90° scattering angle system. This instrument is suitable for the analysis of samples such as emulsions, suspensions, and proteins. technical parameter: Measuring range: 0.3nm-5000nm (subject to the sample) Measuring principle: dynamic light scattering method Repeatability error: <1% (NIST traceable latex standard sample) Minimum sample volume: 20μL The minimum sample concentration is 0.1mg/mL (subject to the sample) Measuring principle: dynamic light scattering, static light scattering Minimum sample volume: 20μL (3-5 sample concentrations are required) Measuring principle: electrophoretic light scattering Sensitivity: 10mg/mL 66kDa protein Zeta potential range: >+500mV / ＜-500mV Electrophoresis speed range: >+20μ.cm/V.s / ＜-20μ.cm/V.s Maximum sample concentration: 40% w/v (subject to sample) Minimum sample volume: 20μL Detection technology: M3-PALS Detection angle: 90°＋13° Laser source: Highly stable He-Ne laser, wavelength 633nm, power 4mW.
