Study on Dicarboxylic Acids in Aerosol Samples with Capillary Electrophoresis
Figure 5
Electropherograms of (a) the air sample 2 and (b) the air sample 3 after solid-phase extraction. Sample collected with a cascade impactor (12 stages). The analyses were performed with two replicates and six repetitions. Electrolyte: 4 mM PDA + 0.5 mM MTAH, pH 11.0; indirect detection at 310/266 nm; sample injection for 6 sec at 50 mbar; separation voltage −24 kV; analysis time 5 min. Analysis conditions as described in Experimental.
