优化粒径分布
颗粒和液滴在化学品、消费品、造纸以及石油行业中无处不在。 颗粒生长、团聚、破碎、溶解以及改变形貌 － 所有这些均会对工艺性能与产品质量产生影响。 要获得成功，化学家和工程师必须充分了解与优化颗粒分布以控制工艺效率，例如稳定性、分离情况或流动特性等。 此外，必须很好地控制颗粒和乳化物分布，以确保可重复的产率、保质期与堆积密度。

应用
PVM Detects Process Upsets
PVM© technology can be used to detect the presence of unexpected polymorphs, even at concentrations below the detection limits of Raman or offline microscopy. By imaging thousands of particles per second, trace polymorph detection is possible where morphology changes exists.
利用颗粒分布控制研发絮凝工艺
絮凝是生化技术、石油、纸浆与造纸和采矿行业常用的一种分离法。 絮凝剂的长聚合物链可吸附到小颗粒上，引发颗粒架桥，促进大絮凝体的形成。 絮凝效率主要取决于混合时间和强度、有效絮凝剂的类型和浓度、加料速率、固体浓度和颗粒粒径。 高效絮凝可影响产品开发和规模扩大、下游分离性能、运行成本和产量。

Monitor and Measure Particles and Droplets In Process and In Real Time
The handling and processing of suspensions and emulsions is critical. Multiphase systems tend to be complex with many parameters, including overall process efficiency and economic profitability, being directly affected by the ability to consistently deal with the production, separation, and/or removal of solid particles and liquid droplets in suspension.
Determine Impact of Process Variables
Liquid-liquid dispersions, or emulsions, are an excellent application for in situ droplet size measurement; sampling these systems for offline analysis can be unrepresentative as the sample can change by the time you measure it offine.
