Determination of Hydrogen in Zirconium and Its Alloys by Melt Extraction under Carrier Gas Flow Using Thermal Conductivity Cell as Detector

摘要

In the production of zirconium metal and its alloys the presence of hydrogen impurity affects mechanical and corrosion resistance properties of the product. Therefore, determination of hydrogen contents of the product is necessary. Conditions for its analysis by melt extraction under carrier gas stream using thermal conductivity cell as detector were studied and optimized. The method is capable of measuring hydrogen impurity in parts per million range.
