The improvement in S/N in progressing from top to bottom spectrum in figure 5-10 needs to be calculated. The factor that improvesthe S/N value in progressing from middle spectrum to bottom in figure 5-10 needs to be determined. Concept introduction: Signal-to-noise ratio (S/N) is a scale used in engineering and science to compare the level of the signal to the background noise. It is defined as ratio of power of signal to the noise and it is expressed in decibels.

Question

Suppose you are analyzing mercury ions (Hg2+) in drinking water samples with atomic absorption spectroscopy. If the Hg2+ signal varies by a matrix of sample, which of the following should be used as a standard for calibration? Either cations or anions can be used if they are different from Hg2+, 0 H20 Any anions can be used if they are different from Hg2+ Any cations can be used if they are different from Hg?". Hg2+
