Microtrac 的 NANOTRAC Flex 是一种高度灵活的纳米粒度分析仪,基于动态光散射 (DLS),可提供有关粒度、浓度和分子量的信息。 它可以通过可靠的技术、更高的精度和更好的准确度实现更快的测量。 所有这些都组合成一个带有革命性固定光学探头的紧凑型 DLS 分析仪。 凭借独特而灵活的探头设计以及在 NANOTRAC FLEX 中使用激光放大检测方法,用户可以选择合适的容器作为测量单元,以满足任何应用的需求。 这种设计还允许在很宽的浓度范围内测量样品、单峰或多峰样品,所有这些都无需事先了解粒度分布。 这是通过使用频率功率谱 (FPS) 方法而不是经典的光子相关光谱 (PCS) 方法来实现的。
The STABINO ZETA provides very fast, precise, and reproducible zeta potential measurements due to its high resolution and data point density, respectively. The STABINO ZETA can measure the zeta potential of particles in a range of 0.3 nm to 300 µm, with a concentration range of up to 40% by volume.
Thanks to the unique measurement technology, the STABINO ZETA can determine five parameters simultaneously within a few seconds. In combination with Microtrac’s DLS analyzer, NANOTRAC FLEX, the size can be measured at the same time, in the same sample.
In addition, the STABINO ZETA has a built-in titration function where all the parameters are analyzed simultaneously at every dosage step. The determination of the isoelectric point is one of the possibilities of titration and is completed within a few minutes.
多功能性是动态光散射 (DLS) 的一大优势,这使得该方法适用于研究和工业中的各种应用,例如药物、胶体、微乳液、聚合物、工业矿物、油墨等等。
