6.3 

Cleaning the nebulizer (standard Crossflow Nebulizer)  

 

 

 

Warning! Risk of injury! 

There may be acid residues or other hazardous residues from sample material in 
the nebulizer and the spray chamber. 

 

Observe the corresponding information on hazardous materials. 

 

 

Warning! Sharp edges! 

Glass parts may break when handled incorrectly and cause cutting injuries. 

 

Proceed with due caution and/or take appropriate safety precautions (e.g., 
wear gloves). 

 

To clean the nebulizer, proceed as follows: 

1. 

Flush the sample introduction system for approx. 10 minutes with a suitable 
blank solution, e.g., distilled water for aqueous applications. 

2. 

Switch off the plasma. 

3. 

Loosen the clamp between the plasma torch and the spray chamber.  

4. 

Carefully pull off the spray chamber.  

5. 

Disconnect all other connections from the nebulizer and the spray chamber. 

6. 

Separate the nebulizer from the spray chamber by slightly twisting it and 
disconnect the argon connection. 

7. 

Remove the adapter for the argon connection. 

8. 

Put the nebulizer into a beaker and carefully fill it with diluted hydrochloric 
acid.  

 

Hazardous substance! 

 

Observe the corresponding information on hazardous materials. 

9. 

Let the acid act for up to 15 minutes (depending on the degree of 
contamination). 

 

When heavy contamination must be removed, another suitable acid or 
aqua regia may be required. 

 

If there are deposits on the capillary tube, remove them very carefully 
with a fine copper wire. Be extremely careful to avoid damage to the 
capillary tube.
