The part of SEM that is responsible for the production of electrons. * Electron guns Condenser lens Secondary detector Electron beam A surface analysis technique used for determining elemental composition on surfaces of solid samples. AFM SEM XRD SIMS XPS A surface analysis technique that uses a cantilever to scan over a region of interest. The cantilever deflects towards or away from the surface due to the attractive and repulsive forces with the sample.

Prepare a 1:200 dilution of the 20 mM Coomassie solution to measure the max wavelength—you need 2 ml for the absorbance measurement but the dilution does not matter as long as the absorbance is in the range of 0.2 to 0.6. Set the initial wavelength at 450 nm. Blank the spec with a tube containing 2 ml water. Use the 1000 ul pipette for water because you need to deliver the same amount of water in each tube for the next exercise. Why is it when the calculations are done for the given values above, the value for ml is 0.01 for coomassie blue?
We can draw three inequivalent Lewis structures for the arsenite ion, AsO3¹. The concepts of formal charge and electronegativity can help us choose the structure that is the best representation 1. Assign formal charges to the elements in each of the structures below. Note: Count oxygen atoms starting from the left for each structure. Formal Charge As 01 -0₂ 03 FO: As. -Ö: A :0³ 2.

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.
