Instructions for calibrating an instrument designed to measure levels of oxidants in the atmosphere. Measuring oxidants is one way to quantify air pollution. Photochemical oxidants are air pollutants which form when air containing nitrogen oxides and reactive hydrocarbons is exposed to sunlight.
Beckman Instruments, Inc. became interested in measuring, controlling, and fighting air pollution in the late 1940s and early 1950s, when company president Arnold O. Beckman became the scientific adviser to the Los Angeles Chamber of Commerce’s Air Pollution Control Officer. Many of the instruments that were developed by Beckman Instruments in the 1940s and 1950s as standalone items became incorporated into or re-purposed as smog-fighting systems.
