Standard aqueous solution of organic pollutants is used for the development of analysis methods and novel water sampling devices. The use of solid-phase microextraction (SPME) and other novel technologies for research in water sampling and analysis requires systems for the reliable generation of standard aqueous solution. In this communication, a new flow-through system based on permeation is introduced for the generation of standard aqueous solution of polycyclic aromatic hydrocarbons (PAHs). The main difference between the new developed system and typical system is that the syringe pump was changed with a permeation generator. The generator-based permeation offers many advantages, including convenient, inexpensive, solvent-free, long lifetime and production of high concentrations of the target analytes. The observed change in the concentration of the six PAH compounds was less than 20% over 3 months.
