When reviewing your results in the Review window, you may have noticed the “Peak Codes” column in the Peaks table. Sometimes it’s empty, sometimes there’s a letter with a number – but what does it actually tell you?

These are processing codes – little flags from Empower that give you hints about integration or quantitation. Some are harmless, some signal issues you shouldn’t ignore.

How to find out what Peak Codes mean?

Open the Empower Help and search for the code (e.g. “I03”). You’ll find a full list under “Interpreting Processing Codes” – super helpful!

Tip: Always take a look at your codes before approving results. They might reveal something you’ve missed.

While there’s no official “critical list,” watch out for these:

• I03 – User manually deleted a peak 

• I04 – User manually deleted a drop line

• Q09 – Result is above the calibration curve

• Q10 – Result is below the calibration curve

• Q14 – User manually identified a peak
