J-SCIENCE | Diffusible hydrogen analysis system
Feature:
- Diffusible hydrogen in steel welds can be easily measured by the gas chromatography method with an accuracy of 1/1000 mL or more
- Hydrogen released from steel welds is called diffusible hydrogen [H]D, and is considered to be the biggest cause of cold cracking in welds
- This measurement method is also adopted by JIS Z3118, ISO3690 and ANSI/AWS A4.3-93
- Measuring method : Gas chromatograph method
- Carrier gas : Argon… Approx. 300 mL/min
- Column : Stainless steel circular coil type, i.d.5mm/o.d.6 mm, 3 m in length, packed with MS-5A, 30/48 mesh
- Detector : Thermal conductivity detector (TCD)
- Oven temperature : 40℃
- Analysis required time : 3 minutes / sample
- Limit of detection : Hydrogen 0.0005 mL
