(PDA) Checking the Water Level in the Argon Gas Bubbler

(PDA) Checking the Water Level in the Argon Gas Bubbler
Category : 


Parts Number: 211-51930  AR GAS BUBBLER (With parts and bottle)
Parts Number: 038-00236  BOTTLE,PE WIDE MOUTH 1LT 
The argon gas bubbler is attached to the argon gas exhaust outlet. Pressure fluctuation in the emission table can be reduced because the water inside the argon gas bubbler works as a stabilizer. Use tap water for the bubbler, and keep the water level within the range of 8 cm to 10 cm.
When the water becomes too dirty, replace with clean water.
After replenishing or replacing the water in the argon gas bubbler, [Recalibration], [Master Curve Correction Recalibration], [Check Analysis with Check Samples] required.
CAUTION: Do not wrap flammable cloth or similar material around the exhaust outlet of the argon gas bubbler.
• When the water level in the argon gas bubbler is too low, the analysis values fluctuate.
• When the water level cannot be confirmed due to contamination of the inner wall of argon gas bubbler, clean the inner wall using a toothbrush.
• Connect a vinyl hose to the exhaust outlet of the argon gas bubbler to release the exhaust air from the room and the bubbler.
  The exhaust outlet diameter is 9 mm.
• Evaporated samples such as iron, aluminum, or copper accumulate in the argon gas bubbler in fine power form.
• If evaporated samples accumulate in the vinyl hose connecting the emission table and argon gas bubbler, analysis values may fluctuate.
• Blow air into the vinyl hose periodically, or replace the hose with a new one.
• Confirm that the emission table exhaust outlet pipe or vinyl hose is not loosened.
  Loose pipe or hose may cause analysis values to fluctuate.
• Confirm there is no deformation or bending in a vinyl hose.
  Deformation or bending of a vinyl hose may result in a fluctuation in the analysis value.
