signal-to-noise determination

Question

Hi

I want to determinate the LOD of my sample by using the method signal-to-noise ratio 3:1 but I can't find the signal to noise value on the ChemStation. How can I get this value? Does the software give you also signal-to-noise ratio (2:1 or 3:1)

Thanks in advanced

To calculate signal to noise in ChemStation you will need to define noise ranges in your method. To define noise ranges in Data Analysis go to Report>System Suitability>Edit Noise Ranges. Once this is done you will need to save the method and reprocess.

You can use either Classic or Intelligent Reporting to report Signal/Noise. For classic reporting you will need to use the Performance+Noise report style. For intelligent reporting you can use the Peak_SignalToNoise_EP, Peak_SignalToNoise_USP, or Peak_SignalToNoise6Sigma fields.
