Brief Method Summary
|
Samples are first subjected to bromination, then are salted out, and extracted. The extract is cleaned up using a Florisil column before being analyzed by gas chromatography (GC) and electron capture detection (ECD). |
|
Scope and Application
|
This method determines trace amounts of acrylamide monomer in aqueous matrices. This method may also be applicable to other matrices and other similar analytes. |
|
Applicable Concentration Range
|
0 - 5 ug/L. |
|
Interferences
|
No interference is observed from seawater or in the presence of 8% of ammonium ions derived from ammonium bromide. Impurities from potassium bromide are removed by the Florisil cleanup procedure. |
|
Quality Control Requirements
|
Refer to Chapter One and Methods 8000, 3500, and 5000 for specific QC procedures. Procedures include: validation of sample preparation, introduction, and analysis, initial demonstration of capability, calibration verification, evaluation of retention times, analysis of method blanks, matrix spikes, duplicates, surrogates, and laboratory control samples. |
