2_1_1270637301_Green Switching - Opportunity to Avoid Sulfr hexafluoride

Sulphur hexafluoride (sf 6) is a man-made gas that is chemically inert, non-toxic, non-flammable, non-explosive and thermally stable at temperatures less than 500C. Sulfr hexafluoride is colourless and odourless and heavier than air. One of the main characteristics of Sulfr hexafluoride is its high chemical stability due to the six covalent bonds of its molecule.Get price

Working fluid exhaust temperatures of up to 5,000 degrees Fahrenheit can be encountered. The exhaust gas is rendered inert and massively reduced in temperature for analysis using a combination of water cooling channels and cool N2 gas injectors in the H2-N2 mixer portion of the test section.Get price

extremely high amounts: Topics by Science.gov

A humidity of 30+/-3% in a closed environment and the overnight drying of the spotted slides gave the best conditions for arraying. In addition, the cDNA dissolved in 30% DMSO gave the optimal conditions for spotting compared to the 1X ArrayIt, 3X SSC and 50% DMSO.Get price
