Quantitative PAH Extraction Analysis

Extraction recoveries were quantitatively determined by an internal standard mix (ISTD) confirmed by two deuterated PAHs in phenanthrene (Phe-d₁₀) and pyrene (Pyr-d₁₀). Supelco EPA 610 PAH Mix was used as the reference standard for the target PAHs. All reagents were at least analytical reagent grade. Specific suppliers and purity grades were previously reported in Mundo et al. (2020) [28 (link)].

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
