名称：纳米颗粒跟踪分析仪, Nanoparticle tracking analysis（NTA）

型号：ZetaView

主要功能：测量粒子的粒径、浓度和zeta电位，测量范围依赖于样品和仪器。对于金样品，颗粒跟踪技术的检测下限为10nm；相应的，如果样品的散射能力较弱，则检测下限会变得更大。假如样品稳定，不会沉淀或漂浮，zeta电位测量的粒径上限为50微米，对于粒径测量为3微米。

The particle size, concentration and Zeta potential are measured, and the range of measurement depends on the sample and the instrument.For the gold sample, the detection limit of particle tracking technology is 10nm.Correspondingly, if the scattering ability of the sample is weak, the lower limit of detection will become larger.If the sample is stable and does not precipitate or float, the maximum size for Zeta potential measurements is 50 microns, and for particle size measurements it is 3 microns.
