We have an older 5975C running Chemstation acquisition G1701EA E.02.00.493. This version did not contain the BFB Autotune tuning program. Our other 5975C the same age had this added by an Agilent tech a few months after the original installation, but for some reason it wasn't done to this system. Does anyone know if BFB Autotune can be added now, and how to go about it? Or is the only option an upgrade to newer acquisition software?
