Bubble Gas Analysis And Identification Of Sources

In this article, the author looks at the factors behind gaseous inclusions in glass. Gaseous inclusions are among the most common of defects affecting glass quality. The position of the bubble in the he glass, the bubble size distribution, the gas content, and precipitated inclusions, together with the knowledge of interaction mechanisms help to identify the source of bubble defects. With the help of a dedicated type of gas mass spectrometer, it is possible to analyse the gas phase in gas bubbles in glass. The GIA 522 system is at present used by Glass Service Inc. During routine analysis several impurities can be analysed at the same time with a high dynamic range. For more information please see: www.gsl.cz
