亲水亲油平衡值HLB为表面活性剂的重要性质，测定HLB的方法很多，气液色谱法被认为是“最有前途”的方法，此法基于溶液热力学性质，在概念上可直接联系表面活性剂的溶解性能，所得结果准确，并可获得更多的热力学数据。
Hydrophile-lipophile balance HLB is an important surfactant property. There are many ways to determine HLB. Gas-liquid chromatography is considered as the “most promising” method. This method is based on the thermodynamic properties of the solution and is conceptually linked to the surface The solubility of the active agent, the results obtained accurate, and can obtain more thermodynamic data.
