I am using a 6430 agilent triple quad LC-MS. I am using masshunter version 08.02
Lately we have been having a randomly occurring communication error. It has been occurring when a sequence is running at some random point. A series of communication errors will popup between the LC modules and the software. Then all the modules including the triple quad will go offline.
The only way to reestablish communication is to power cycle everything. I've tried clearing masshunter processes, restarting software etc.
This is a new problem with this instrument. The only things that have recently changed is computer was linked to a network drive for data backup. I did disable this network connection but the error still occurred. The only other difference is I have been running the instrument in dynamic MRM mode. I still haven't confirmed that the error only occurs in this mode but I will keep trying to troubleshoot that.
I tried a few different troubleshooting recommendations from agilent service engineer. Checking windows firewalls, checking ip communication (it pings).
Not sure what else to do here. Could be ethernet card maybe. Could be this network drive software. I don't really know. Any ideas?
