From time to time, we all face problems with HPLC instruments. Then, we all search the internet for the solution for our problem. In this troubleshooting section I would like to point out my problems with instruments and their solutions. Hopefully, it can help also you.

Recently, I was asked to run the HPLC-MS instrument which was off for several months. The LC part was Agilent 1100 and MS was from the Bruker (HCT+). The instruments themselves worked fine, but there was a problem with their connection. At least I thought so. The Agilent HPLC went always to power off mode after couple of minutes. No matter what I have done, no matter what I have tried. It always went to shutdown mode.
