Automated system for fast and accurate analysis of insulating gas

The system runs on an hourly cycle during which one set of four gaz sf6 standards is measured and insulating gas derived from the seawater stream is subsequently analyzed for the rest of each 1 h period. This state-of-art system was successfully used to trace a water mass carrying Cochlodinium polykrikoides, which causes harmful algal blooms (HAB) in the coastal waters of southern Korea.

On the Melting Curve of Sulfur Hexafluoride | NIST

Nov 09, 2017 · Abstract. A previous correlation for the melting curve of sulfur hexafluoride (gaz sf6) is inconsistent with the thermodynamic slope at the triple point derived from the Clapeyron nist-equation. It is shown that this is probably due to the previous authors combining an accurate measurement of the triple point with melting-curve data that were distorted by impurities.
