Two separate series of CuSO₄ homeopathic preparations and controls were prepared, while there was one series of samples for sulfur (S) and quartz (SiO₂). Lab 1 is a wet laboratory at the University of Illinois at Urbana Champaign and Lab 2 is a 100HEPA clean room at the National High Magnetic Field Laboratory, Tallahassee, FL. At Lab 1 a Perkin-Elmer λ14 and at Lab 2 a Perkin-Elmer λ3B UV-spectrometer were used. Samples of Lab 1 and Lab 2 were all measured by coupled plasma mass spectrometry at Lab 2.
