I recently acquired a Beckman pump (126) that is having issues with pumping the correct volume. I'm an Agilent and Waters guy, and have little experience opening up a Beckman pump, although I'm sure its quite similar, I was hoping someone had the maintenance manual for this pump? I cannot seem to locate it online, and was not given a hard copy with the instrument. Also, the system controller is a NEC (Beckman) PE-8300 "computer" which is the most primitive computer I have ever seen in my life. It's like a fancy graphing calculator that controls an HPLC, anyways, I was also hoping that someone either had a manual for that, or could help me to program a gradient method using it. I am having issues transferring a method from my Agilent 1100.
Thanks in advance!
