EPA Method 8011:
1,2-Dibromoethane and 1,2-Dibromo-3-chloropropane by Microextraction and Gas Chromatography

Samples are extracted with hexane and are analyzed using a gas chromatograph equipped with an electron capture detector.

This method determines the concentration of EDB and DBCP in drinking and ground water.

(A) Contamination: Impurities found in hexane used in extraction is the source for the majority of interferences. These impurities may be discovered through the analysis of reagent blanks. The impurities can be removed by distillation or column chromatography, however, it is recommended to obtain a new source of hexane solvent. Sample contamination may occur by diffusion of volatile organics through the septum seal during shipment and storage. The analysis of trip blanks will identify this problem.(B) Matrix interferences: The extraction technique extracts a wide range of non-polar organic compounds and some polar organic compounds. EDB at low concentrations may be masked by high concentrations of dibromochloromethane when using the confirmation column.

QC Requirements:
Periodic analysis of laboratory reagent and calibration blanks, reference and check standards, spikes, and replicates as a continuing check on performance.

Maximum Holding Time:
See SW-846 Chapter Four for information.



0.03 - 200 ug/L.

Sample Prep:
Method 8011

Precision and accuracy values were calculated using data from 7 replicate analyses of tap water during a single laboratory study.

To establish the ability to achieve low detection limits, prepare seven samples each at a concentration of 0.03 ug/L. Analyze accordingly. Then, calculate the average concentration and the standard deviation of the concentrations for each analyte, using the seven results. Then, calculate the MDL at 99% confidence level for seven replicates as 3.143s. The average concentration must be between 60% and 140% of the true value, and the MDL may not exceed the 0.03 ug/L spiked concentration.
