名稱✊🏼：納米顆粒跟蹤分析儀, Nanoparticle tracking analysis（NTA）

型號🏈：ZetaView

主要功能：測量粒子的粒徑、濃度和zeta電位，測量範圍依賴於樣品和儀器。對於金樣品👩🏽‍🔧，顆粒跟蹤技術的檢測下限為10nm🧎🏻‍♂️‍➡️；相應的🧝🏻‍♂️，如果樣品的散射能力較弱，則檢測下限會變得更大。假如樣品穩定🚐，不會沉澱或漂浮，zeta電位測量的粒徑上限為50微米⛹🏿，對於粒徑測量為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.
