Application of two-level full factorial design and response surface methodology in the optimization of inductively coupled plasma-optical emission spectrometry (ICP–OES) instrumental parameters for the determination of platinum

Inductively coupled plasma optical emission spectrometry (ICP-OES) determination of platinum was optimized using 2-level, 4-factor full factorial design and response surface methodologies. Four factors, namely carrier gas flow rate, sample solution flow rate as represented by the pump speed, plasma observation height and RF power, were employed in the factorial design. Analysis of variance (ANOVA) at a p-value...
