Rezumat. Lucrarea este dedicată studiului metodelor matematice pentru separarea
picurilor cromatografice parţial suprapuse: scăderea sectorului cromatogramei de fond,
modelarea cromatogramelor cu utilizarea funcţiilor algebrice şi de aparat. S-au discutat
avantajele şi dezavantajele fiecărei metode, propunîndu-se propriile recomandări la
optimizarea algoritmilor de calcul corespunzători. S-au selectat două modele algebrice –
Gauss exponenţial modificat şi Asimetric bisigmoidal, care descriu mai adecvat picurile
reale, aparente în HPLC. Experimental, s-au evaluat erorile analizei cantitative a
cromatogramelor în funcţie de gradul de suprapunere a picurilor şi nivelului de zgomot la
utilizarea modelelor algebrice şi de aparat.
This paper is dedicated to research of mathematical methods for separation of particular
overlapped chromatographic peaks: subtraction of sectors of background chromatogram,
modelling of chromatograms using apparatus and algebraic functions. Surveyed of advantage
and disadvantages of each method, the own recommendations on optimisation of the
corresponding computing algorithms are given. Two algebraic models – Exponentially
Modified Gaussian and Asymmetric Double Sigmoid – most adequately describing real peaks
apparent in HPLC have been selected. The experimental estimation of chromatograms
quantification errors depending of various peaks overlapping and noise level is carried out at
usage of apparatus and algebraic models. |
