颗粒表征仪

Morphologi J3通过静态图像分析技术测量颗粒粒度及粒形。 测量过程包含了三个基本阶段；

• Sample preparation and dispersion
  This step is critical to getting good results; spatial separation of individual particles and agglomerates is the goal. Morphologi G3SE具有集成式干粉分散装置，可轻松地对干粉样品进行重复备制。 The applied dispersion energy can be precisely controlled, enabling the measurement process to be optimised for a range of material types. Dispersion is achieved without explosively shocking the particles, avoiding the damage of fragile particles while ensuring strongly agglomerated materials are dispersed. Effective dispersion of fibres can also be achieved. 
• Image capture
  The instrument captures images of individual particles by scanning the sample underneath the microscope optics, while keeping the particles in focus. Morphologi J3的光源可从下方或上方照射样品，同时可实现精确控制。 偏振光学装置可用于研究双折射材料。 
• Data analysis
  The instrument measures a range of morphological properties for each particle. 软件中先进的图表与数据分类选项，通过直观的界面，确保尽可能直接地从您的测量中选取相关数据。 每个颗粒单独存储的灰度图像可为定量结果提供定性验证。
