Gas Analysis Equipment ( Blowhole Gas Analyzer VBH-100 )

PDFを表示 Quantitative & Qualitative Analysis of ultratrace gases in blowholes
Suitable for various Material Evaluation


  • Quantitative and Qualitative analysis of gases emitted from blowholes of specimen in vacuum chamber is possible by using Quadrupole Mass Spectrometer( QMS ). Blowholes are appeared in Steel Welded part, Continuous casting material, Casting
  • QMS which has High Sensitivity & Resolution gives capability of easy and detail analyzing of the gases in blowholes existed in Steel, Nonferrous metals, Glass, etc.




・ Cause investigation of material defect
・ Material Design Verification
・ Evaluation of Surface Contamination
・ Specify degassing condition
