Abstract
A liquid cell for in situ atomic force microscopy (AFM) measurement of a sample during filtration is provided. The liquid cell includes a cantilever probe; a cantilever holder to position the probe near a surface of a sample (e.g., a filtration membrane); a liquid cell housing provided to hold the sample and comprising an opening at the top; an upper part; a lower part; an internal cavity to contain a fluid; a fluid inlet passage located in the upper part; a first fluid outlet passage located in the upper part; and a second fluid outlet passage located in the lower part. A method of in situ atomic force microscopy (AFM) measurement of a sample during filtration in a liquid by using the liquid cell described herein is also provided.
