When calculating the signal to noise ratio, are you comparing the HEIGHT (Intensity) of the respective peak with the average HEIGHT (Intensity) of the noise in the chromatogram. or are you comparing the AREA of the respective peak with the AREA of the noise?
If its comparing areas, how do you measure the AREA of noise, as we have some strange situation here with root mean squares and peak areas!
Please explain a little as Im fairly clueless about this!
