Usp Signal To Noise Calculation

Usp Signal To Noise Calculation. My measurements are n = 66 and s = 367 (arbitrary units). Can anyone tell me where the 2 comes from?

My measurements are n = 66 and s = 367 (arbitrary units). Most workers calculate s/n just as the ratio of the signal to the noise, so s/n = 367/66 = 5.56 in this example. Usp s/n cannot calculate because peak to peak noise is either zero or blank

The best way is to pick several locations around the peak, measure their noise levels, and average the results. By chrisknutsen » fri jan 08, 2010 6:10 pm the current usp chapter on chromatography says to calculate the s/n ratio by 2h/hn, where h is the height of the analyte peak and hn is the height of the noise. Λ 2h s/n = where:

So, for complex calculations, you divide the value of the desired signal by the amount of the noise and then take the common logarithm of the result, i.e., log (s ÷ n). H = height of the peak (figure 1) corresponding to the component concerned, in the S/n = 2 h/h where:
