detecting sulphur hexafluoride Analysis

For some reason, I find molecular sieve packed columns interesting. Maybe it's because they have a niche as the go-to columns for fixed (permanent) gas analysis. Maybe it's because they are old school technology that a new generation of analysts are always asking questions about. Maybe it's because using them successfully is a function of skill, art, and some luck. As I researched ...

  • 6. ANALYTICAL METHODS

    The sensitivity of this method is enhanced if sulfur hexafluoride-doped hydrogen gas is used (Lioy and Waldman 1989). The advantages of using flame photometric detector analysis include low maintenance, high sensitivity, fast response, and no interference from nonsulfur species. However, this method is unable to discriminate between sulfur species.
