Determination of Selected Polycyclic Aromatic Compounds in Particulate Matter Samples with Low Mass Loading: An Approach to Test Method Accuracy

Table 1

Measured mass of selected PACs (ng) obtained from analysis of subsamples using the investigated extraction procedures. PM (mg) and correspond to PM mass loading expressed in mg and sample number, respectively. The abbreviations for PACs and extraction procedures are expanded in Reagents and Standards and Samples and Preparation, respectively.
