This thesis deals with a summary of individual method for determining of hyaluronan concentration, especially in aqueous solutions. Selected methods were compared to their functionality in university workplace. Any functional methods may be used for many purposes in university workplace in research of materials based on hyaluronan. It has been studied usability to assess residual content of hyaluronan in supernatant of gel formed from hyaluronan and surfuctant, in this thesis. We choosed sptectrophotometric methods, especially with UV spectroscopy and IR spectroscopy. Two precipitation methods using alcian blue were also tested. As the most reliable, the least demanding and specific method seems to be the method using IR spectroscopy, thanks to it we are able to determine the concentration of HA from 0.01 %. With this method, it has been found, that if there will be located some amount of HA in supernatant, it will be below the detection limit of assay. The remanining methods were modified to help determine the concentrations of HA, but works only in aqueous solutions. A possible variation for determination of very low concentrations of HA may be the method using ELISA kits. However their cost is higher than the above-mentioned methods.
