主要规格及技术指标

Principle: Nanoparticle Tracking Analysis (NTA) is a technique that utilizes the Brownian motion characteristics of nanoparticles to measure their size, distribution, and concentration. This method involves illuminating a nanoparticle suspension with a laser beam, capturing the scattered light signals from the nanoparticles, and employing a high-resolution imaging system to track the particles' movement trajectories within the suspension. By analyzing these trajectories in conjunction with the Stokes-Einstein equation, the hydrodynamic diameter of the particles can be calculated, thereby providing information on particle size, size distribution, and concentration.
原理：纳米颗粒跟踪分析技术是一种利用纳米颗粒布朗运动的特性来测量其尺寸、分布和浓度的技术。该技术通过激光照射纳米颗粒悬浮液，捕捉纳米颗粒的散射光信号，并使用高分辨率成像系统跟踪颗粒在悬浮液中的运动轨迹。通过分析这些轨迹，结合斯托克斯-爱因斯坦方程，可以计算出颗粒的流体力学直径，从而得到颗粒的粒径大小、分布和浓度信息。
