In your Peaks Table, there’s a column called Int Type. Each peak has two letters – your chromatogram’s secret code language 📜. They tell you how the peak start and end were set, i.e. how it was integrated.

Here are the common ones:

• B – baseline – peak start/end lies right on the baseline
• V – valley – start/end “hovering” above baseline with a dropline
• S – shoulder – the neighbour peak is a shoulder
• E – exponential – neighbour peak separated with exponential skim
• T – tangential – neighbour peak separated with tangential skim
• G – gaussian – neighbour peak separated with gaussian skim
  
  

Capital letters = automatic integration
Lowercase letters = manual integration

This is worth checking – especially if manual integration is a hot topic in your lab 🔥.
