Dear all. i found that spray chamber was frozen and the chiller's temp was 20.  could you tell me why the spray chamber was frozen ??? Model : ICP-MS 7900

 

 

symptom :  The vent line was not correctly working. 5% Nitric acid is venting a little bit.

 

                 Sensitivity is too low because sample sprayed is frozen in the spray chamber .
