Soil quality — Determination of linear alkylbenzene sulfonate (LAS) — Method by HPLC with fluorescence detection (LC-FLD) and mass selective detection (LC-MSD)
|Publication Date:||1 September 2012|
|ICS Code (Chemical characteristics of soils):||13.080.10|
This Technical Specification specifies a method for the determination of liner alkylbenzene sulfonate (LAS) in sludge, treated biowated biowaste and soil using high-performance liquid chromatography (HPLC) with a fluorescence detector (FLD) or a mass selective detector (MSD).
This Technical Specification specifies the determination of the sum of LAS. Under the conditions specified in this Technical Specification, typically a limit of detection of 20 mg/kg (expressed as dry matter) for sludge and of 0,2 mg/kg to 0,5 mg/kg for soil and treated biowaste may be achieved.
Lower limits of detection may be achieved by concentrating the extract by solvent evaporation.
NOTE The single LAS homologues C10 to C14 can be determined by this Technical Specification.
