Analysis of PAH by Reversed Phase HPLC

Polycyclic Aromatic Hydrocarbons (PAH) determination in soil, food, air, body fluids etc. has been a topic of interest for routine Quality Control or Screening Analyses. This Method offers good Resolution, reproducible Retention Time and Peak Shape for these compounds. In addition to the main components, small peaks due to impurities or decomposition products are well Resolved in the easy, isocratic Method.


Peaks:
1. Naphthalene
2. Phenanthrene
3. Guaifenesin
4. Pyrene
I. Impurities or Decomposition Product
