采用多波长激光对外泌体、病毒等纳米材料样品中的所有颗粒进行完整、详细的分析。
外泌体、病毒和纳米颗粒都具有较宽的粒径分布，这使得传统的纳米颗粒追踪分析 (NTA)仪无法准确测量它们的粒径分布。ViewSizer 3000的三个激光器可同时工作，可在同一样品中收集各种尺寸的*准确的分布和浓度信息。如果某一颗粒来自某一激光的散射光信号太强使检测器达到饱和，软件会自动使用来自较低功率激光器的数据来确保获得*准确的尺寸和浓度信息。另一方面，当来自某一激光的散射光信号太弱而无法检测时，软件会使用更高功率激光的数据来准确跟踪颗粒。
交叉污染是所有分析中都存在的问题。简化清洁意味着**清洁。易于拆卸的样品池可以拆卸以进行快速、**的清洁，从而获得更好的数据。
摆脱传统 NTA 的限制
准确灵敏的分析，无交叉污染

ViewSizer 通过多激光纳米颗粒追踪分析技术 (NTA) 得到颗粒粒径及粒径分布。多个激光器可分析同一样品中各种不同尺寸的颗粒，分辨率更高。
NTA 可用于对测量体积中的颗粒进行计数。该测量方法可校正粒径对有效测量体积的影响。
样品池可**拆卸，拆卸后清洗更方便**。拆卸、清洁和重新组装比冲洗流通池更快。此外，配备多个样品池可样品测量通量，也可分配给共享（核心）设施中的各个小组。
