Discussions about GC-MS, LC-MS, LC-FTIR, and other "coupled" analytical techniques.
Both of my 5890 Series II have EPC that can do constant flow and I think they were purchased around 1980. One of them has an additional flow controller so it can do programmed pulses and ramps using either pressure or flow.James_Ball wrote:
Do you remember at what point the EPC was capable of doing constant flow?
I can't remember if the first ones only did constant pressure or not.
