Dispersive Liquid Liquid Micro Extraction (DLLME) is a technique used to extract analytes from a product matrix and provide a level of enrichment for trace analysis testing.
A dispersive agent is added to the sample prior to the addition of a chlorinated solvent, either dichloromethane or chloroform. For the work with GSK, chloroform was used.
