Project 2: Food Dye Spectroscopy Week 1 Organizational Questions Define λmax-How can solutions of different colors be used to determine the relationship between color and Amax? 1. At what wavelengths should the readings be taken? What instrumentation will you utilize with a solution of a known dye to determine the wavelength for your analysis? If your solution is too strong or too weak to give accurate readings, what will you do to get better 2. 3. results? 4. What is the relationship between absorbance and transmittance? 5. How can you use serial dilutions to determine the relationship between concentration and absorbance? Graphs may also help in this explanation.

Experiment: UV-Vis Spectrophotometry and Beer’s Law Absorption of Light of Dyes in Beverages A calibration curve for the orange dye in a soft drink was obtained by plotting absorbance against concentration (M) for a series of solutions of known concentration. The slope of the calibration curve was 226 L/mol and the intercept was -0.011. The absorbance of an unknown soft drink was found to be 0.333 under the same conditions as the calibration curve. Calculate the concentration of the orange dye in the soft drink.

The LC-MS (mass spectrometry) is set to positive mode (can only see positively charged ions). What is the other routine mode which the instrument can be set in and when would this mode be used and why?
Any phd experts there??? Question 34. In the course material you have been introduced to multiple charging for electrospray spectra. Each peak in the spectrum below can be used to provide a measure of the mass of this protein, you can work out the charge associated with each peak, and measures can be averaged to find the overall mass. Use simultaneous equations to find the charge associated with each peak in the spectra below, which will allow you to calculate the average mass of each species. Include an estimate of the error associated with this measure. Graph for Intrpt. Below is samples see calculation etc

"[FeSCN2+]eq is calculated using the formula: [FeSCN2+]eq = Aeq/Astd x [FeSCN2+]std where Aeq and Astd are the absorbance values for the equilibrium and standard sample respectively." I am confused about what Aeq and Astd mean. We did an experiment where we measured the absorption of this chemical formation and I got around 0.18. Is that one of the values?
