"WebThe weak part of the needle-in-loop autosampler is the high-pressure needle seal. This seal must withstand the full pressure of the HPLC system, which may be as high as 6000 psi (400 bar) for conventional HPLC systems. With higher-pressure UHPLC systems, use of this design can be very challenging. Different autosamplers use different seal ... " - Full loop injection hplc

WebJan 1, 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.
