New hybrid sol-gel coating for solid phase Microextraction
A new 2-hydroxymethyl-18 crown-6 and polydimethylsiloxane (2OHMe-18C6/PDMS) hybrid fiber coating for solid phase microextraction (SPME) was prepared using sol-gel technology with methyltrimethoxy-silane (MTMOS)as precursor and hydroxy-terminated polydimethylsiloxane(OH-TPDMS) and 2OHMe-18C6 as coati...
