This poster explores the use of very low sample and elution volumes with 10 mg format EVOLUTE EXPRESS CX products for urine panel analysis.
An extraction protocol using a 10 mg mixed-mode cation exchange sorbent (EVOLUTE® EXPRESS CX) was developed and various sample sizes were assessed to determine the optimal sample volume for a 98-compound DOA panel. A method involving microelution off of the sorbent requiring no evaporation or reconstitution steps were also developed.
