What is the purpose of the flame in AAS? {Ans: -evaporates the solvent -atomizes the sample so the individual components can be analyzed}What type of sample is AAS used to analyze? {Ans: samples requiring high sensitivity due to very small levels of analyte with a specific absorption line width, and for trace metals}Principle components of a GC {Ans: Mobile phase reservoir --> [Sample injector --> stationary phase --> Detector] --> readout OVEN in brackets}HETP equation {Ans: L / N}equation to find unknown amount analyte using RF {Ans: (amount ethanol / amount IS) = (area ethanol / area IS) x RF}Block diagram of a fluorescence spectrum {Ans: Light source --> monochromator --> sample cell --> monochromator --> photodetector --> readout}desirable qualities for IS in GC {Ans: similar in structure to analyte but not present under analysis}All strong acids {Ans: HCl, HBr, HI, HNO3, HClO4, H2SO4}Calculate RF for mixture containing ethanol: 8.0 x 10^-5 M with an area of 122,000 1-butanol:6.4 x 10^-5 M with an area of 172,000 {Ans: 1.76}Calculate volume 0.2 NaOH and # equivalence points for titration of 25mL 0.1 H3PO4 {Ans: 2 eq points- 0.1M x 0.025L =
