Description / Abstract:
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.
