方法/原理/步驟

　　Morphologi G3通過靜態(tài)圖像分析技術(shù)測量顆粒粒度及粒形。測量過程包含了三個基本階段；

　　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裝置，可輕松地對干粉樣品進(jìn)行重復(fù)備制。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 G3的光源可從下方或上方照射樣品，同時可實現(xiàn)精確控制。偏振光學(xué)裝置可用于研究雙折射材料。

　　Data analysis

　　The instrument measures a range of morphological properties for each particle.軟件中先進(jìn)的圖表與數(shù)據(jù)分類選項，通過直觀的界面，確保盡可能直接地從您的測量中選取相關(guān)數(shù)據(jù)。每個顆粒單獨(dú)存儲的灰度圖像可為定量結(jié)果提供定性驗證。

儀器設(shè)備

　　自動化SOP控制的無人值守式運(yùn)行與可重復(fù)的結(jié)果使生產(chǎn)率直線上升。

　　質(zhì)量卓越的顯微圖像保證準(zhǔn)確表征

　　Integrated dry powder dispersion with accurate dispersion energy control automates sample preparation for repeatable and reproducible measurements of both fragile and robust materials

　　作為共享的實驗室資源，先進(jìn)的人工顯微控制模式可提供更多的價值

　　在膜濾器上快速實現(xiàn)自動化顆粒計數(shù)

　　直觀強(qiáng)大的軟件界面可使您更容易地對數(shù)據(jù)進(jìn)行直觀判定與統(tǒng)計分析。
