1. Improvements in the Winkler Titration for Iodide in Iodized Salt
Kenneth W Pratt, Karen E Murphy
A bromine gas generator, based on bleach, potassium bromide and dilute hydrochloric acid, replaces hazardous pure bromine used in the classical Winkler titration for iodide. This modification eliminates the need to store or use pure bromine. The ga ...
2. Measurement of Scattering Cross Section with a Spectrophotometer with an Integrating Sphere Detector
Journal of Research (NIST JRES)
Lili Wang, Steven J Choquette, Yu-Zhong Zhang, Victoria Karpiak, Adolfas Kastytis Gaigalas
A commercial spectrometer with an integrating sphere (IS) detector was used to measure the
scattering cross section of microspheres. Analysis of the measurement process showed that two
measurements of the extinction, one with the cuvette placed i ...
