Analytical Tips

  • Some of the components with the low-vapor pressure in PAMS and TO-14A are gradually condensed in cylinders depending on time elapsed, storage temperature, and usage environment after manufacturing. As a result of it, lower concentration may be detected. Cylinder heating systems provided by RIGAS will help you to use those components at the correct concentration.
  • Components with low-vapor pressure or strong adsorption may be adsorbed during the analysis process. It will cause difficulty to detect accurate concentration. With regulator heating systems provided by RIGAS, the concentration stabilization time of the components can be shorten and ensure accurate figures.
