LB Se/Soil Signal to Noise Ratio

To create the plots shown below, each split run was analyzed. The signal to noise ratio, mathematically

[math]\displaystyle{ \frac{Signal - Background}{Background} }[/math]

was taken during each time cut and plotted vs. the start time of the measurement.

50% Se Soil Mix

Below are the plots for the signal to noise ratio of both the pure selenium and mixture.
