The use of specialty gases in the automotive industry has increased rapidly in recent decades. Car head lamps contain Xenon; indicator lamps contain Argon and Nitrogen. Sheet metal for doors and the car body is cut with lasers using gas mixtures. For optimum fuel efficiency, tires are filled with Nitrogen.
Fuels and lubricants are produced with the aid of many calibration gases mixtures and high purity gases for process control and analysis. In the production and quality control of automotive engines, a variety of specialty gas mixtures are used to calibrate analyzers, such as atomic absorption spectrometers (AAS), to ensure that emissions are minimized and fuel consumption and performance are optimized. Highly durable, high purity specialty equipment installations are also essential for the reliable supply of these calibration gas mixtures. To ensure on-road vehicle engines are running with environmental efficiency, many state and federal governments stipulate periodic emission test requirements.
