"WebThe guidelines for sample injection volumes are as follows. If the injection volume is too large, the peak shape will become deformed, or the injection port will become dirty, leading to problems. Liquid samples: Approx. 1 to 2 µL Gas samples: Approx. 0.2 to 1 mL. Liquid samples become a gas at the stage of injection into the column. " - Full loop injection hplc
