This application demonstrates the usefulness of SPME in the low-level extraction of agricultural pesticides from wine, and the use of the SLB-5ms in the subsequent analysis. The pesticides chosen for the analysis represent a group of insecticides and fungicides that could be found in commercial wines. These compounds contain a variety of polar functional groups, and the polyacrylate fiber provided the selectivity necessary for extraction from a wine matrix. The inertness and low bleed of the SLB-5ms enabled subsequent low-level analysis of these compounds by GC-MS.
