  • Page 52: Argon Gas Bubbler

    4 Operation Operation Argon gas bubbler An argon gas bubbler is installed on the argon gas exhaust line. The water in the argon gas bubbler works as a resistance to suppress the pressure fluctuation in the spark stand. Keep the water level in the argon gas bubbler at 8 to 10cm. Replace the water if it is heavily contaminated.
  • Page 53 4 Operation Note ● When the water level in the bubbler lowers, the analytical value varies. ● Connect a vinyl hose or something similar to the outlet of the bubbler to discharge the exhaust air from the bubbler out of the room.
