Figure 2. Extracted ion chromatograms of phenylated and bistrifluoromethyl phenylated organic and inorganic mercury. Ph: phenyl group; BTFMPh: 3,5-bis(trifluoromethyl) phenyl group. Mercury compounds in standard solutions were derivatized using sodium tetraphenylborate and sodium tetrakis [3,5-bis(trifluoromethyl) phenyl] borate separately and combined for this analysis. Ions were monitored in the scan mode of electron ionization.
