Monitoring of PAHs in simulated natural and artificial fires by HPLC-DAD-FLD with the application of Multi-Component Integrated calibration method to improve quality of analytical results

[Display omitted] •Novel calibration approach for monitoring of hazardous materials is proposed.•Integrated calibration method was adapted to multicomponent analysis.•Method is applied to the determination of polycyclic aromatic hydrocarbons.•Utility of the method is confirmed by analysis of air samples in simulated fires.•Method is White (RGB model) – is a good candidate of choice for all applications. Modifications of integrated calibration method (ICM) in its basic variant and complementary dilution method version (CDM) were adapted to multi-component (MC) analysis to obtain novel calibration approaches improving the accuracy of analytical results. Methods were developed conceptually and their performance was assessed on the basis of polycyclic aromatic hydrocarbons (PAHs) determination in air samples. The natural (thuja needles) and synthetic (polymer) materials were combusted simulating fires or home users’ combustion. Analytical method for determination EPA PAHs was developed using HPLC-DAD-FLD. It has been confirmed that the improved analytical results accuracy obtained in MC-ICM and MC-ICM/CDM was described by relative error
