为什么纳米粒度仪器颗粒检测不准?

  现在广泛使用的纳米粒度仪与我们常用的激光粒度分析仪相比,这是一个巨大的应用,但是,随着粉末工业的发展和纳米技术工业化的加速,这些设备的市场也在不断改善。在这种设备名称的情况下,“动态光散射”一词比激光粒度测试仪更多。

  严格来说,在颗粒测试过程中,灰尘样品不能被引入到电池中,我们知道,如果PM2.5为2.5微米,则如果实际测试样品为纳米颗粒,则微米颗粒的实际光强度会通过。小颗粒的散射光强度将完全消失。实际上,纳米粒度仪新疆福彩18选7走势图的制造商还规定了其测试样品的多分散系数要求。因此,如果您的纳米粒子热化剂测试结果和电子显微镜相差很大,那么您首先应该认为您正在测试的纳米粒子测试样品的多分散系数远远超出了动态光散射仪器可接受的范围。
