Express Bubble Gas Analysis

Identification of the following bubble sources:

Batch melting Reboil Refractory outgassing Electrolysis Mechanical entrapment Redox changes Water leakage Glass melt contamination

Identification of bubble sources is based on the following analytical data:

• Bubble gas composition
  The following gases are analyzed: O2 , N2, CO2, SO2, Ar, H2, COS, H2S, CO, H2, (H2O).
  Additional gases may be analyzed on request.
  
• Total internal pressure in kPa
  
• Interpretation/evaluation of results
  Based on more than 20 years of experience in the field of glass technology, GS furnace engineers always
  include an estimation of the possible source and probable location of a bubble based on evaluation of its features.
