{"id":26,"count":8,"description":"<strong>Gas Grades and the Importance of Purity<\/strong>\r\nOne of the most important criteria for selecting a gas is its purity level. Gases are produced in various grades to meet the needs of general industries, sensitive production lines, and research centers. The higher the gas purity, the lower the level of impurities present. Selecting the appropriate grade is very important and can directly affect the accuracy of results and the quality of the final product.\r\nFor example, in the TIG welding process for aluminum, grade 3.5 is sufficient, but for GC analysis in a pharmaceutical laboratory, grade 5.0 is required. If you are unsure about selecting the right grade, consult our experts.\r\n\r\n\r\n\r\n\r\n\r\nGrade\r\nApproximate Purity\r\nSuitable Application\r\n\r\n\r\n\r\n\r\n2.5\r\n99.95%\r\nGeneral industrial applications\r\n\r\n\r\n3.5\r\n99.95%\r\nSpecialized industries\r\n\r\n\r\n4.5\r\n100.00%\r\nLaboratories and sensitive equipment\r\n\r\n\r\n5.0\r\n100.00%\r\nResearch and ultra-sensitive processes\r\n\r\n\r\nSpecial\r\nAbove 50%\r\nAdvanced industries and specific applications\r\n\r\n\r\n\r\n\r\n<strong>Selection Guide by Industry<\/strong>\r\nKeep in mind that choosing the wrong gas \u2014 both in terms of process quality and safety \u2014 will be costly.
