    The Breathalyzer is an instrument designed and developed by Borkenstein for use by law enforcement agencies for rapid, accurate, convenient, and positive recognition of alcoholic intoxication as defined by law. Because the use of the Breathalyzer as a means for determining the alcohol (ethanol) concentration of the blood has recently increased, the judge of a Justice Court in Spokane, Washington desired to know more about the reliability of the instrument. A Breathalyzer used by the Washington State Patrol in the Spokane area was provided for a detailed investigation. This instrument (Model 100) was examined and operated after delivery under a variety of experimental conditions to determine any errors or inconsistencies in its performance. The investigation involved only the Breathalyzer and its accessories and did not include tests of human subjects or physiological tests.
