Application Note: Analysis of EPA 610 Polynuclear Aromatic Hydrocarbons
3 November 2018
Polynuclear aromatic hydrocarbons (PAHs) are a hazardous class of compounds which are readily found from drilling and burning of fossil fuels. To test for the presence of PAHs in ground and waste water, the US Environmental Protection Agency (EPA) has developed a variety methods which can be done on LC/UV, such as EPA 610. To build upon these existing methodologies and analyses, Phenomenex designed and developed a special polymerically bonded C18 stationary phase fused to a Kinetex core-shell silica particle. This particle and phase combination greatly improves selectivity for hard to resolve PAHs, while providing dramatically increased sensitivity (limit of detection) and better overall LC performance.
