Specialty Gases - Linde Gas

1 Specialty GasesSpecialty GasesTitle page: The atmosphereSundown in orbit. The earth's atmosphere, photographed from an altitude of 300 kilometers during the D-2 Mission (April/May1993). A pink-colored layer can be seen about 15 kilometers high. The color indicates particles of sulfuric acid and ammonium sulfate, caused in turn by an immense presence of sulfur particles released a few days before by the eruption of Mount with the kind permission of the DLR German Aerospace This CatalogMany fields of application in high-tech-nology industrial processes, research anddevelopment, instrumentation and medicinerequire high-purity Gases , high-quality gasmixtures and appropriate gas handlingequipment such as efficient pressure regulators and customized gas this catalog we present the broad range of our product linesand services.

4 Our new poli-cy in this field (see overleaf) also defines our responsibili-ty to our customers, employees, the authorities, societyat large and the introduced a certified quality management systembased on ISO 9001 in most of our group companies world-wide. We also meet other specifications, in the fields ofnuclear technology, medicine and pharmacy as well as for theautomotive and semiconductor industries. Our Specialty gas activities are, therefore, firmly embeddedin a comprehensive quality management is of essential importance to our work. The aim ofour publications on the characteristics, transportation andhandling of our products is to ensure their safe use.

5 Details onthis are included in this catalog. Our customer consultantsand safety experts will also gladly help you in your individualquestions and protectionIt is our concern that no harm to the environmentemanates from our Gases at any stage from production andstorage through distribution to use and disposal. We realizethis on the basis of applicable laws and in some cases evengo beyond QSE Management System withcertificateLinde was the first gas company in Germany to introduce amanagement system for quality, safety and the environment(QSE) in its operations and to have it certified for all its busi-ness premises according to DIN EN ISO 9001 (quality ma-nagement), SCC (safety management) and DIN EN ISO 14001(environmental protection management).

6 Meanwhile a numberof operative units in other countries followed this aim of our management system is to ensure constantimprovement in our internal and external services. We placesimilar demands on our suppliers, service-providers and complaints and deviations from our internalstandards are systematically analyzed and detailed correctiveand preventative measures introduced. Work processes areregularly checked for efficiency and our employees encour-aged to improve their qualifications. In this way we will con-tinually improve our products, processes and to our customersThe general objectives of our integrated QSE ManagementSystem are: Environmentally safe products and services Safety in their supply and use Constant high product quality Individual, competent advice Consistent orientation to the needs of our customers56 Pure Gases78 Sample extraction9 Pure GasesLinde's current product portfolio of pure Gases isintended to cover as many fields of application inproduction, work safety, environmental protectionand research and development as possible.

7 Its spe-cial Gases for the semiconductor industry are alsoincluded in this chapter. An overview of the mostimportant information on them is listed under "Elec-tronic Gases ".To aid in finding the Gases , the index that followsincludes old or customary gas names in addition topresently applicable terminology. The descriptions ofthe Gases contain details of their purities, completecylinder information as well as all major gas data andproperties. Further physical specifications, vaporpressure curves, etc. can be found in the chapter"Information, Tables and Diagrams".Industrial Gases and their mixtures are not dealtwith in detail in this catalog. Separate literature isavailable on these Gases .

8 An overview of the entirerange of Linde Gases is contained at the end of information for the use of thesegasesDefinition of purity: The minimum purity of agas refers to the specified impurities that characteri-ze the pure gas. The specific limits for the impuritiesare not exceeded. In the case of Gases withoutdetails on impurities, the specification of their purityis to be seen as a typical the case of a number of high purity Gases ,every filled cylinder is accompanied by a certificateof analysis confirming that the maximum limits forimpurities have not been exceeded. This is noted forthe gas purities to which it applies. It does not applyto " Gases in Small Containers".

9 Cylinder fillings fre-quently display purities that are higher than thosewhich have been guaranteed. Even if this shouldoccur repeatedly, it should nevertheless not be takenas any assurance of uniformly higher information:The purity of the Gases is indicated bya short suffix serving as an abbreviated indication of the mini-mum content of a pure gas. The first digit in the suffix indica-tes the number of "nines" in the specification of the gas's puri-ty in percent. The second digit indicates the first decimal placenot "nine". The first and second digits are separated by apoint. Examples: Ethylene % purityArgon % purityInstead of the short suffix, a few Gases have an applicati-on-related suffix, Nitrogen CO-free.

10 Irrespective of theminimum purity indicated in the product description, thesegases have an especially low residual content of certain other-wise troublesome information: The percentages indicated inconjunction with purities or impurities are mole percents (idealvolume percentages). Extremely low percentages are indicat-ed in ppm or ppb (1 ppm = 1 part per million = 10-4%; 1 ppb = 1 part per billion).Volume information: Unless otherwise expressly stated,the following applies: 1 m3of gas is the volume of gas that will filla cube having an edge length of 1 m at a temperature of 15 Cand a pressure of 1 bar. One liter of gas is one thousandth ofthe gas volume thus defined.
