EPA Method 1613:
Tetra- through Octa-Chlorinated Dioxins and Furans by Dilution HRGC/HRMS

Samples are extracted, cleaned, and concentrated. Extracts are analyzed using high resolution gas chromatography/high resolution mass spectrometry (HRGC/HRMS). An individual CDD/CDF is identified by comparing the GC retention time and ion abundance ratio of two exact m/z's with the corresponding retention time of an authentic standard and the theoretical or acquired ion-abundance ratio of the two exact m/z's. Quantitative analysis is performed using selected ion current profile (SICP) areas.

This method determines tetra- through octa-chlorinated dibenzo-p-dioxins (CDDs) and dibenzofurans (CDFs) in water, soil, sediment, sludge, tissue, and other sample matrices.

EPA Method Guidance CD-ROM (includes MCAWW Methods, and most current EPA Methods)

(A) Glassware contamination: Thoroughly clean glassware as soon as possible after use with solvent, sonication, and multiple rinses. Do not bake reusable glassware as part of routine cleaning.(B) Reagent contamination: Use high purity reagents.(C) Matrix interferences: Demonstrate matrix is free from interferences by running reference matrix method blanks. The natural lipid content of tissue can interfere in the analysis of tissue samples. Remove by lipid removal process.(D) Extracted interferences: Interference from extracted non-target compounds, with retention times similar to target compounds, can be reduced by cleaning the extract.

QC Requirements:
The minimum requirements consist of an initial demonstration of laboratory capability, analysis of samples spiked with labeled compounds to evaluate and document data quality, and analysis of standards and blanks as tests of continued performance.

Maximum Holding Time:
1 year (prior to extraction).



Not Available.

Sample Prep:


The Minimum Level (ML) for each analyte is defined as the level at which the entire analytical system must give a recognizable signal and acceptable calibration point. It is equivalent to the concentration of the lowest calibration standard, assuming that all method-specified sample weights, volumes, and cleanup procedures have been employed.
