Short Lab Report Examples and Guide

ABC-GCMS Report:Cover page should have your name, your partner’s name, the date and your unknownletter.1. Calculate the concentrations of acetone, benzene and chloroform in themixture using the GC peak integrals, using appropriate internal standard andstandard addition formalism. Show your work. (See next page for details.)2. Attach a chromatogram that shows all of the peaks and their integrals.3. Attach the MS and library match for each peak in ONE of thechromatograms.4. Indicate the likely structures for at least two ions in each mass spectrum.Fluorescence Report:Cover page should have your name, your partner’s name, the date and the experimenttitle.1. Experiment design. Write a sentence or short paragraph indicating theprocedure you devised to produce the 1 μM rhodamine 6G.2. Plots: (see example on next page) Plot both absorbance and fluorescencespectra on the same graph in Excel. Use the following guidelines (8 pts)a. Multiply the fluorescence spectrum values by a constant to give it roughlythe same amplitude as the absorption spectrum.b. Use two different line styles, (i.e. solid and dashed) but no symbols for theplots. Use only black and white.c. No background color.d. No grid lines unless these are necessary to convey information on theplots.e. Appropriate sig-figs on axis labels.f. Use a reasonable font size and a simple font like Arial, Helvetica or Times.g. Give the graph a minimalist appearance. Use the minimum amount of inknecessary to convey the information that you want to for the graph.h. Minimize wasted space in the graph.i. Include a legend indicating which plot is fluorescence and which isemission.3. Indicate the absorption and fluorescence emission processes using arrows of theappropriate relative lengths on a reproduction of the energy level diagram providedbelow.a. Label the axes on the diagram. (2 pts)b. Use arrows on the figure below to indicate:i. Initial state and final states describing the absorbance process. (2 pts)ii. Initial state and final state describing the laser excitation process. (1)iii. Initial state and final states describing the fluorescence emissionprocess. (2 pts)
