Adscientis反气相色谱表征不同类型乳糖（原料，微晶化，处理过）表面特性

         The surface properties of lactose play an essential role for the behavior of these powder in inhalers. The different Inverse Gas chromatography methods are providing very interesting tools for characterizing the surface of lactose powders.
        This application note compares the surface characteristics of a same lactose powder different stages of the preparation process in order to be used in inhalers (not milled, milled and conditioned). The determined surface characteristics are: the surface energy, nanoroughness, acid-base character, specific surface area and adsorption energy distribution functions.
       The applied treatments are modifying significantly the lactose surface nanoroughness. This seems to be an important parameter for  understanding the behaviour of this type of powder.

      在吸附剂粉末中，乳糖的表面特性对于吸附剂的吸入有非常重要的作用。不同类型的反气相色谱方法对于表征乳糖粉末有非常重要的作用。

     本文对比测定了不同生产过程间的乳糖（研磨前后，或者表面处理过的）表面特性。表面特性参数包括：表面能，纳粗糙度，酸碱特性，比表面积和表面能量分布。
