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. WebbThe simplest way to inject your sample into the system.

WebbAs a rule of thumb, we can inject approximately 15% of the volume of the first peak of interest if we inject in mobile phase. For example, if the first peak is 0.1 min wide at the base and the flow rate is 1 mL/min, the peak volume is 100 µL, so a 15-µL injection in mobile phase should be possible.
