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.

Claim (Index 17):
A method of in situ atomic force microscopy (AFM) measurement of a sample during filtration in a liquid, comprising:\n providing a liquid cell of  claim 1 ; positioning a sample inside the liquid cell housing to separate the liquid cell housing into the upper part and the lower part, and separate the internal cavity of the liquid cell housing into an internal cavity above the sample and an internal cavity below the sample; disposing at least one O ring on each side of the sample; connecting a fluid source to the fluid inlet passage, connecting a retentate receiver to the fluid outlet passage in the upper part, and connecting a permeate receiver to the fluid outlet passage in the lower part; injecting a fluid from the fluid source to the internal cavity above the sample through the fluid inlet passage; positioning the cantilever probe near a surface of the sample through the opening of the liquid cell housing; and making AFM measurements.
