...Polycyclic aromatic hydrocarbons (PAHs) are among the most frequently monitored environmental contaminants. Standard and official methods for PAH analysis are listed in compilations for the analysis of air, drinking water, wastewater, solid waste, and food. Most of these methods recommend HPLC, typically with UV and fluorescence detection, as the analytical procedure. Waters' PAH columns are...

...Fluorescein (or uranine) is a reference tracer used in hydrology for locating underground watercourses or leaks in pipelines (wastewater and stormwater networks), measuring river flow, and identifying ocean currents... In its concentrated form, it easily dissolves in water to create a ready-to-use mixture. It appears fluorescent yellow in daylight and exhibits green fluorescence under UV lamp lighting.
