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 ...
