Optimization of solid phase microextraction conditions for determination of triazines

A simple, solvent-free, and field-compatible approach to sample preparation is provided by the basic process known as solid-phase micro extraction (SPME). The aim of this study was improve circumstances under which triazines were extracted from aqueous matrices. complex technique enabled detection analytes in water at a physiological level. An evaluation practicability most commercially available fiber coatings has been conducted. porous materials (Carbowax/DVB PDMS/DVB) more efficiently than homogeneous ones (PDMS polyacrylate). Further investigation focused on 65 mm PDMS/DVB fiber. Solid phase microextraction based partition equilibrium between Therefore, 60 minutes required reach room temperature. desorption efficiency 3 temperature levels had compared 270 °C retained. Experiments performed with Finnigan MAT GCQ Model installed 30-m x 0.32-mm ID, ZB-5 (0.25-mm film thickness) fused-silica capillary column, Helium carrier gas (at 30 kPa), ion trap mass spectrometer operated electron ionization (EI) mode.
