ONH Inert Gas Fusion, diff. H by Hot Extraction - Application Training

About the training

This training course is designed for new and existing users of the G8 GALILEO or G4 PHOENIX inert gas system family. The course covers the theoretical fundamentals, sample preparation techniques as well as methods of qualitative and quantitative analysis. At the end of the training the attendee knows the theoretical and practical fundamentals for a reliable day by day usage of such inert gas fusion (ONH) or hot extraction (dH) analyzers.
