- Abstract
Quality assurance is the key factor in producing reliable, trustworthy and reproducible analyses results. The goal of this research is to demonstrate the modality of results quality control in the scope of wine analyses and thus the qualification of laboratory, by implementation of internal and external quality control for four selected parameters:relative density, alcoholic strength, volatile and total acidity. Internal quality control is carried out by applying control charts for in-house reference material and external quality is carried out by the participation in interlaboratory comparison examinations. Here are presented the results of laboratories data statistical processing from which the success of participation in interlaboratory comparisons is being estimated. Based on the presented results we can conclude that laboratory successfully implemented quality control of testing results during controlled period for four analyzed parameters, because the reference material results did not exceed the specified limit values. Laboratory has successfully participated in interlaboratory comparisons which was confirmed by obtained Z-values that were between -2.00 and +2.00 for all tested parameters. By application of presented control procedures, high quality of testing results is achieved.
