The development of modern pharmaceuticals relies heavily on modern laboratory equipment for which specialty gases are essential. The pharmaceutical industry is one of the fastest growing industries in the world. Revenues are reinvested in the area of research and development of new products. Analytical instruments such as chromatographs and spectrometers all rely on the appropriate level of gas delivery to operate effectively. The quality of these gases are specified in pharmacopeias and performing tests is a real industry challenge since it requires dedicated analytical equipment and fully validated sampling method. During production, gases are used to synthesize, to sterilize, or to insulate from undesirable environmental effects such as oxidation.
