采用PCCS原理对纳米颗粒进行粒度和稳定性的测试

摘要

最新的研究成果-光子交叉相关光谱原理(PCCS-Photon Cross Correlation Spectroscopy),完全避免了光子相关光谱原理(PCS-Photon Correlation Spectroscopy)的纳米粒度仪原理上的缺陷,可以直接测量高浓度样品而不需稀释,测量结果完全真实的反应了被测试样品的实际粒度分布状态.文中详细介绍了PCCS的测试原理和应用,采用该原理的仪器,由德国新帕泰克公司制造并向全球推广,型号为NANOPHOX.%A recent development, known as photon cross-correlation spectroscopy or PCCS, has dramatically extended the power of the original technique and enables reliable measurements even in high concentration suspensions. This article describes the theory and applications of PCCS and also the practical embodiment of the technique, namely the new NANOPHOX instrument from the Sympatec company.
