德国L.U.M. GmbH 
利用粒子移动受重力或离心力所驱动以及光学近红外检测的理论基础，德国LUM仪器公司开发了专利技术的全功能稳定分析仪系列产品，可以对样品进行分散性、产品存放期、分层稳定性以及粒径大小和粒径分布（百分比率分布）等性能分析，广泛适用于产品的研究、开发、配方改进、流程优化、质量保证等。 LUMiSizer 更被 ISO认定可以准确分析试样的粒径（Particle Size）和分布。

The L.U.M. GmbH is one of the leading producers for analytical devices for dispersion analysis and particle characterization. The company has developed the innovative STEP®-Technology, which is the technical platform for different product lines. The produced measuring equipment is used for the fast, reliable and comprehensive characterization of any demixing phenomena in dispersions as well as for the measurement of Particle Size Distributions in concentrated dispersions. The innovative devices are part of standard laboratory equipment in leading international companies of chemical, food, cosmetics, pharmaceutical and paint/pigment industries.
