New Standard Test Method for the Determination of Polynuclear Aromatic Hydrocarbons in Aqueous Environmental Matrices Using UPLC Technology

    (What is a Work Item?)

    Developed by Subcommittee: D19.06 | Committee D19 | Contact Staff Manager


    1. Scope

    1.1 This test method covers the determination of the following polynuclear aromatic hydrocarbons (PAH, aka PNA): acenaphthene, acenaphthylene, anthracene, benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthrene, benzo(g,h,i)perylene, benzo(k)fluoranthene, chrysene, dibenzo(a,h)anthracene, fluoranthene, fluorene, indeno(1,2,3-c,d)pyrene, naphthalene, phenathrene, and pyrene. 1.2 Additional analytes, such as, 1-Methylnaphthalene, 2-Methylnaphthalene, decafluorobiphenyl, p-Terphenyl-d14, decachlorobiphenyl, Coronene, benzo(b)chrysene, benzo(e)pyrene, and perylene can also be determined, but it is beyond the precision and bias of this method. It is incumbent on the user to ensure the validity of this method for these analytes. 1.3 This method is applicable to the analysis of the 1.1 analytes in drinking water, surface water, and POTW effluents. This is not intended for industrial discharge effluents, or water sample from oil refineries or steel production industries. 1.4 Several milliliters of sample containing PAHs (polynuclear aromatic hydrocarbons) are concentrated onto a solid phase extraction cartridge and eluted into 1 mL volume. One hundred microliters (mL) are injected into a UPLC system for separation. Detection is achieved using UV at 254 nm, and analyte specific excitation/emission fluorescence. Using sample enrichment, PAH analytes can be determined at ppt concentrations (pg/L). 1.5 This method is a state-of-the-art liquid chromatography method using a 1.7 mm bridged ethane hybrid C18 reversed-phase columns generating greater than 6000 psi system pressure. Ultrahigh Performance Liquid Chromatography is the state-of-the-art liquid chromatography technology offering fast analysis times and increased sensitivity compared to HPLC. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
