RegisterTransparent ruler – like in the good ol’ days [Bioanalytics]
Dear Helmut and ElMaestro,
That's how I do it too. I don't trust automatic calculations by whatever software. It depends so much on the parameters you enter. You may get a S/N of 30 with the plot you provided. Nonsense.
With a visual quick and dirty look I would have said 3, but I was too fast and I was wrong (stupidly took the signal from the bottom of the graph). Revised slower-and-still-dirty estimate 2.
❝ Eyeballing, of course.

❝ Peak height 13.7 gives S:N ~1.8. Not an awful lot.
