Sodium lauryl ether sulfate Sles' method
Sodium lauryl ether sulfate SLES Method Summary
The sample is heated and extracted in a headspace vial. The extract is analyzed by GC-MS. Qualitative identification is based on the relative abundance ratio of ions, and quantification is performed using selected ion monitoring (SIM) mode. The content is calculated using the standard addition single-point method.
The detection limit for dioxane is 2μg, and the lower limit of quantification (LOQ) is 6μg. If a 2.0g sample is used for determination, the detection concentration of dioxane is 1μg/g, and the minimum quantitative concentration is 3μg/g. Sodium lauryl ether sulfate SLES.
