I am currently trying to separate out polymers using SEC * RP. In the beginning I had smooth chromatograms, but all of a sudden the chromatograms have started showing a zigzag pattern in the second dimension. I have attached an image below:

I was wondering if anyone knows what could cause this problem or has any suggestions on how to fix it? The lamp has just been replaced, so I was wondering if this means the problem could lead to the flow cell or the pump?
Thanks!
