Introduction
Motivation: PAH and PCBs Most Often Analyzed Pollutants
Conspicuously Missing Are Fragmentation Patterns
PAH, PASH Library-building Process
Example 1.
Combinatorial Library Building of Alkylated PAH and PASH
Schematic of a generalized PAH electron impact fragmentation
Standardized Method Retention Windows for C3 Phenanthrene, m/z 220
C4 Phenanthrene
Example 2.
Ion Analytics Data Analysis Software
Example 3.
Example 4.
