An Argon Humidifier is commonly used in ICP analyses involving samples with high concentrations of dissolved solids. It helps to alleviate salt deposits in the nebulizer and torch injector, allowing uninterrupted and maintenance-free operation.

We installed and ran samples with the argon humidifier into both the Thermo iCAP 7000 ICP, as well as our ICPMS. We noticed that the iCAP ICP could handle TCLP samples which have a very high sodium matrix much better. Typically, the carrier gas pressure would creep up from 250 to 450 and we'd have to clean the nebulizer after 1 run of TCLP samples. Now, the carrier gas pressure stays low for longer. Fantastic!

The (Elegra) Humidifier (and adjusting our pump speed) really helped to stabilize the drift we were previously experiencing between QC checks and especially helped combat some of our high TDS samples. Our runs have greatly improved.

(In reference to the Elegra) Talking with my operators that are here today neither of them has changed a nebulizer since we put it on........We had been replacing nebulizers after about a week and half........I will be ordering 2 more.

I'm very happy with the performance of the Elegra so far. It's been in use since Sep 14th and we haven't had to change or clean the neb once.
