摘要：
The present invention provides a method for measuring net charge density of membrane and apparatus thereof. The method measures the net charge density of a membrane by utilizing the relation between the mechanical pressure difference applied across the membrane and the generated streaming potential or the relation between the applied electric field and the generated electroosmotic flow. The present invention also provides a method and an apparatus for measuring the resistance of a membrane.
