We recently noticed an excessive amount of liquid coming out of port 4 of our injection valve assembly (on the auto sampler). I tried doing some googling and couldn't find anything to indicate where the liquid is coming from. We went through the system, cleaning out the valve assembly and we are still having this issue. Any suggestions on where to troubleshoot next?
We are using an Agilent 1100 series HPLC. Please let me know if there is any other information you might need,.
