Chapter 21, Problem 21.8QAP
Interpretation Introduction

Interpretation:

The instrumental difference between static SIMS and dynamic SIMS, the difference between information obtained from static SIMS and information obtained from dynamic SIMS, the imaging SIMS and types of information obtained with imaging SIMS should be determined.

Concept introduction:

Secondary ion mass spectroscopy (SIMS) is used to maintain the integrity of the surface by using static or dynamic condition in the time scale duration of the experiment.

True or False 1. Photodiode arrays are devices within the instrument that help amplify the signal of a sample. 2. Atomic spectroscopy requires the atomization of a sample, which involves nebulization and eventually volatilization to form an elemental vapor. 3. Organic compounds are normally analyzed in atomic spectroscopy despite their small electronic transition range.
Which is TRUE for spectroscopy of a mixture?   A. The absorbance for a mixture at a particular wavelength is the sum of the absorbances for the components that absorb at the particular wavelength.   B. Spectrophotometers can differentiate between mixture components that absorb at the same wavelength.   C. Each component in a mixture has the same molar absorptivity at the same wavelength.   D. The concentration for each component in a mixture is easily calculated by least squares for guesses of each component when the individual spectra are well resolved.
B.  Quantitative Spectroscopy   Prepare two graphs, %T vs. Concentration and Absorbance vs. Concentration, using the data for the cobalt standards.  The concentrations of Cobalt standards 2-4 can be calculated using simple dilution calculations. Concentration should be on the x-axis for each of these graphs.  The first should clearly show some curvature while the second should be a linear curve. Using the absorbance graph you can determine the concentration of the unknown. Take the absorbance value for the unknown and find that value on the y-axis.  Draw a horizontal line from that point on the y-axis to the plotted line.  From the point where the horizontal line intersects the plotted line, draw a vertical line straight down to the x-axis.  Record the value from the point where you hit the x-axis as the unknown concentration.
