Study on Dicarboxylic Acids in Aerosol Samples with Capillary Electrophoresis
Figure 3
Comparison of enrichment in ME after circulating the samples twice with those made with SPE (Oasis HLB). Sample 25 × 25 cm2. The order of the analytes C1–C10 is from left to right. The DCA concentration is 5 mg/L. The results are averages of six replicates. The calculations are based on electropherograms of the standard mixture that were analysed after sample collection from the acceptor solution. 100% is normal recycling (see Experimental) and 2x recycling is twice the same sample volume (limited with timing). Analysis conditions as described in Experimental.
