Complete range of high purity gases
From “A” for argon to “X” for xenon, Messer offers an extensive range of high purity gases. This ranges from the “air gases” (nitrogen, oxygen and argon), carbon dioxide, carbon monoxide, hydrogen and the noble gases (helium, neon, krypton and xenon) through to the most important organic (e.g. methane, ethane, ethylene, acetylene, etc.) and inorganic gases (e.g. ammonia, chlorine, sulphur dioxide, etc.).
Reliable product quality
The reliable product quality is the most important property of high purity gases. Strict quality management is therefore essential. We accurately ensure the quality of our raw materials and production stages and verify compliance within the specifications. Dependent upon the filling process and quality specifications, the control measurements range from batch to individual cylinder analysis. The individual application defines the quality requirement of the gas. Due to the extreme variety of applications and corresponding specifications of gas purity and maximum quantity of disturbing impurities, Messer provides high purity gases in several quality grades. For easy identification of product quality, the point notation system has become generally established. This indicates the purity based upon two numbers: the number before the decimal is the number of "nines", and the number after the decimal is the final number, which is not a nine. For example: a purity of 99,9996 % is abbreviated as 5.6, with a maximum sum of 4 ppmv for the specified impurities.
