Abstract: Rezumat. Lucrarea este dedicată evaluării influenţei unor parametri de digitalizare şi diverşilor algoritmi de prelucrare a semnalelor cromatografice la precizia şi siguranţa marcării cromatogramelor, determinării parametrilor picurilor şi fidelităţii rezultatelor cantitative. Autorii propun propria apreciere a frecvenţei optime de achiziţionare a semnalului analog de intrare, adecvării algoritmilor de filtrare a zgomotului şi exceselor, depistarea capetelor şi determinarea coordonatelor vârfului picurilor cromatografice, pe exemplu cromatogramelor, obţinute la analiza materialului biologic. S-a făcut un şir de recomandări pentru optimizarea algoritmilor de prelucrare a cromatogramelor în cazuri dificile. Summary. The work is dedicated to estimation of the influence of digitization parameters and various algorithms of chromatographic signals handling on accuracy and reliability of chromatograms marking, determination of peaks parameters and on fidelity of quantitative results. The authors have yielded an own estimation of necessary frequency of the input analogue signal acquisition, adequacy of some algorithms of noise and excesses filtration, detection of limits and determination of top coordinates of chromatographic peaks on an example of chromatograms, characteristic for cases of biomaterial analysis. Some recommendations on optimization of chromatogram handling algorithms in difficult cases have been made.
