WebbThe injection of a 0.5 µg/L PFOA solution (Figure 2) shows two peaks. The first one at 16.69 min is PFOA in the injected solution at 0.5 µg/L, while the second one at 17.59 min corresponds to the delayed PFOA interference from HPLC lines and solvents. The injection of a methanol blank showed no interference at the expected retention time. WebbDear HPLC experts, we currently have rather huge problems with our G1329A autosampler - it does not constantly inject the right volume (which is crucial for quantitative analysis).
