Webb1 jan. 2024 · The maximum injection volume is 75% of the total loop and needle volume. Injections larger than the recommended maximum volume can result in reduced sample recovery. Apply the following formula to calculate the maximum injection volume: Maximum injection volume (μL) = [loop volume (μL) + needle volume (μL)] × 0.75. 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.
