Processing width area intuition
These look pretty straightforward to understand. Anything below that area or height won’t be considered a peak.
Example:
If we raise the minimun peak area to 230:
Same thing for the peak height, as we can see its 58 but if we make it 61 we remove that peak.
When in COP nothing shows up in the sample, (it looks like a water blank)
You report it as less than your LOQ which is 1.1 ppm for equipco
If something shows up you report that number.
