The Comparison of the Three Methods of Specific Surface Evaluation – Adsorptive Porosimetry, Inverse Gas Chromatography and Mathematical Method.

In the present study an attempt to determine the possibility of using novel measurement techniques for the evaluation of medical implants was made. The focus was put on the measurements of the specific surface area and associated characteristics of the knitted monofilament meshes made of polypropylene, used for the hernia treatment. As a part of examination, three methods of examination were compared - adsorptive porosimetry, inverse gas chromatography and mathematical method. The obtained results of the specific surface area confirmed the hypothesis stating that the results of specific surface area measurements depend on the applied measurement method.
