Waxy semisolids, today the formulation vehicle for many pharmaceutical and personal care products, present a considerable challenge when it comes to particle size analysis, primarily because they are not liquid at ambient temperature. By taking a new approach to particle sizing for these materials using the Mastersizer 2000 system fromMalvern Panalytical,Unilever的研究人员现在对他们进行了可靠的测量来充满信心,这些测量正在进入改进的产品开发,制造和质量控制。
“粒度是影响我们许多产品质量和性能的关键参数,”Mark Flanagan,Unilever的方法化学家“,但在室温下没有液体的测量材料构成了相当大的问题。我们的解决方案已经到了欧洲杯足球竞彩将Hydro 2000SM小体积样品分散单元放置在高温Waterbath中的Mastersizer 2000。通过Malvern南大略的应用团队得到了完全支持的,他们帮助克服所涉及的技术挑战。结果是我们现在可以实现半固体样品的热分散,并产生真正可靠的粒度测量。“
这个新的particl和高度成功的方法e size measurement in semisolids is significant for Unilever since it provides the company's formulators and QC specialists with a tool for improved understanding and control of their products, and one that will also inform product development.
由于其快速的测量能力,准确和可重复的分析,广泛的测量范围以及测量许多不同样品类型的灵活性,大展会2000已成为许多行业的激光衍射系统。它对粗粒级分的变化特别敏感,因此是用于研究由例如附聚,乳化剂或沉降产生的样品不稳定性的优异工具。
