how to auto-integrate the overlapped peaks?

I'm currently use chemstation for intergrating the peaks. I use autointegration function to analyze the peaks. However, I have a overlapped peaks (around 5 min below photo) and I want to know how to auto-integrate them with the function.

I look forward to your answer from expertise.

Hello,

That does not look like a peak at just over 5 min. Is this a valved system or do you change something in the method around that time like a flow rate? It looks more like a baseline shift than a fronting peak. If the time of that shift is consistent, I would use a timed event like baseline now just after the shift to force the system to reset the baseline.
