I am a new user of Agilent HPLC system. However, I have long experience with LC systems from other manufacturers. In my current workplace, I have an Agilent HPLC which is under maintenance. I am missing the correct fittings that connects from mixture to the passive inlet valve. The connection fittings to that valve looks like flangeless flat bottom with 1/16 ID. I would be grateful if anyone can provide the P/N for that fitting.
