* A gold hollow cathode tube was selected for the procedure. The wavelength of the lamp was 242.8 nm. | * A gold hollow cathode tube was selected for the procedure. The wavelength of the lamp was 242.8 nm. | ||
* Two blanks were used; water and HCl. Water was chosen since it is part of the ternary mixture. The standards provided by [[User:Abigail E. Miller/Notebook/CHEM571 Lab Project/2012/10/08|Dr. Miller]] were made with HCl. In addition, HCl ionizes better and keeps the metal in solution. The standards were 5, 8, 10, 15, 20, 25, 30, 40 ppm Au which appeared as clear and colorless liquid solutions. | * Two blanks were used; water and HCl.
