## 4 Result Analysis and Discussion
A larger series of samples are used to make the measurements more effective, where the samples are simultaneously exposed to different environments. Alternatively, if the character of the material allows and the result is not distorted, it is possible to divide the sample into smaller parts, which increases the area of the sample and intensifies its saturation more quickly. The area and especially the thickness of the samples often have a non-negligible dimension, therefore the time for the moisture to enter the sample to redistribute and reach equilibrium state is significantly prolonged. * Samples contamination: Another phenomenon affecting the accuracy and reproducibility of results is the opening of the chamber or desiccators. The time until the dish is closed takes a few seconds, or due to the size of the sample, it is not always possible to use closable dishes, as in the case of our experiments. The degree of contamination bias together with the accuracy of the weighing depends on the experience of the operator, the measurement technique and the type of measured samples. * Measurement stability and suitability: Stabilizing the weight of the sample while applying these methods takes considerable amount of time, and constant collection and weighing of samples can damage them if handled carelessly. This risk rises with low-density samples, which are more fragile and prone to disintegrate. The possibility of simultaneous exposure of several samples and parallel measurement brings a slight improvement to the measurement stability. However, even here it is necessary to mind the optimal capacity of the desiccator or chambers, so the samples do not interfere with the moisture. In general, conventional methods work well at a lower relative humidity for larger and higher bulk density samples. At a higher humidity, the variance of the measured values increases, and the results are prone to errors due to limitations in the equipment and methodology. * DVS method: The results for the whole curve can be obtained within a short period, which can significantly save measurement time, even when it is necessary to test a large number of samples. Continuous mass measurements and a shorter measuring time together with a high accuracy scale enables a higher accuracy of the results. The sample is not contaminated during measurement and there is no risk of damage during weighing. The limitation of this method stems from the significantly higher purchase price of the equipment compared to the air-conditioning chambers or desiccators, as well as the consumption of energy and measuring gas. * Accuracy and repeatability: The DVS system is characterized by a higher accuracy and repeatability of results compared to conventional methods. The robustness of the system is also ensured by the automation of the entire process. Just at a very high relative humidity do changes in the moisture content of the material take place very slowly. These changes, expressed as the change in mass moisture concentration per minute, take place at a very high humidity, and in order of the resolution of the system itself and its error. Therefore, at a very high relative humidity, the DVS system also shows higher variance, even when increasing the measurement accuracy of the DMDT criterion. This will not affect the measurement accuracy, but its reliability slightly decreases. Despite this fact, dynamic vapor sorption appears to be a very progressive and robust method that surpasses conventional methods in many ways. Continuous weighing and shorter measuring times together with the high accuracy of the scale result in a higher accuracy. The sample is not contaminated during measurement and there is no risk of damage during weighing.
