“…Some of the selected time pairs were 60-80, 80-110, 150-200, 250-300 and 350-420 s. Greater time increments caused higher sensitivity and steeper slopes of the two time axes, as shown previously by Campins-Falco et al [29]. Also, the accuracy of determinations was affected by the slope increments of Hpoint plots.…”

“…By plotting the analytical signals versus added analytical concentration, two straight lines are obtained that have a common point H with coordinates (C H , A H ); C H is the unknown analyte concentration and the A H is the analytical signal due to the interferent species .The HPSAM has been used, eliminating blank bias error due to the use of an absorbent blank [15][16] . HPSAM has also been applied to liquid chromatography 17 , analysis kinetic data analysis [18][19][20][21] with an additional variant time and in metal speciation [22][23][24] .…”

“…These methods essentially are based on different strategies of mathematical strategies including specific formalism of mathematical statistics and of matrix algebra [Garrido et al, 2004;Szabadai, 2005]. The matrix-based methods reffer to quantitative analysis [Bosch-Reigh et al, 1991;Garrido et al, 2008;Li et al, 2011;Lozano et al, 2009;Ruckenbusch et al, 2006;Szabadai, 2005], to determination of the number of independent chemical equilibria in multicomponent systems [Szabadai, 2005] and for correction the action of various perturbing factors such as stray light or backgroud absorption [Burnius, 1959;Fox & Mueller, 1950;Melnick, 1952;Morton & Stubbs, 1946, 1947, 1948Owen, 1995;Page & Berkovitz, 1943;Szabadai, 2005].…”
