    In this work the results of the last two years of measurement were analyzed. Although the overall data sample is large, it contains measurements of densities of several pure compounds and hence the samples of comparable data are not large enough for a reliable statistical analysis. For this reason mathematical gnostics was applied for data analysis. It is a nonstatistical method derived from the fundamental laws of nature, such as thermodynamics and special theory of relativity. Being based on the theory of measurement and properties of each single measured datum, the estimators derived from matmematical gnostics are valid even for small data samples. In addition, no assumption of the type of the distribution of experimental errors is used, the distribution function is estimated during the analysis. This approach allowed us to obtain more robust results identifying the impact of all sources of uncertainty and estimate the typical shape of the distribution function of the measured density and excess volume..
