Faraday Laboratories
Manufacturer of Quartz Crystal Microbalance Instruments
Dan McKeown, president of Faraday Laboratories, holds the patent for the invention of the Quartz Crystal Microbalance (QCM). Faraday Laboratories is a leader in the research and development of quartz crystal instruments used to measure contamination in clean rooms, thermal-vacuum chambers and space. All significant advancement in this field has resulted from the work that began in 1957 with the invention of the QCM. Faraday Laboratories was incorporated in California on June 13, 1967.
