I'm retired, so going by memory. I thought that one could program in a maximum pressure into software like Agilent that would shut off the pump if that pressure was reached.
Maybe I'm incorrect.
yes and no;
normally one can program such a shutdown, but that pressure is measured before the column; so you would limit your working pressure to this low setting.
Unless you have a pressure transducer after your column, you're stuck with passive components.
The "T" options as suggested by lmh seems the only option.
Maybe you can even split the flows, so that only a minor flow goes to the MS and the rest goes to the optical detectors? Depends on your sensitivity (maybe it could be even superior for the MS when feeding it with lower flow rates).
Then only a simple "T-piece" would be needed without any pressure regulators at all.
