Hello, I have a problem with the stability of my cooling water flow at our ICP MS 7800.

Hi Isabella,

sometimes small Particles block the Flow.

To prevent them, being flushed through the whole system, there is a strainer at the back of the instrument.

You can open it, with a 17mm wrench. If there are particles, just clean it with water, and consider changing the cooling water. I recommend to use the 

Agilent Cool Clear

Have you tried, to disconnect the two spray chamber cooling water lines? If not, please disconnect them and have a look the water flow then. 

Best luck

Chris
