It is standard practice to use dry argon for the nebulizer gas in ICP to generate an aerosol and transport the sample to the plasma. However, with samples containing high amounts of total dissolved solids (TDS) there is an increased likelihood of salt deposits forming at the tip of the nebulizer and injector which can result in significant analytical drift in or even an extinguished plasma. To successfully measure challenging sample matrices with high TDS, it is important to optimize your ICP sample introduction system including a:
Adding an argon humidifier such as the Elegra, will reduce maintenance and the chance of an extinguished plasma owing to a blocked nebulizer or injector.
The elegant design of the Elegra is compact and made of inert, metal-free materials so it is easier to fit into the often crowded, harsh environment of the sample compartment of any ICP.
The novel, highly efficient membrane technology adds moisture to the argon nebulizer gas without the need for pressurization or electrical heating. The Elegra can be configured as either a:
The Elegra is available in range of configurations with customized gas connectors to exactly suit a your ICP.

Some matrices like lithium metaborate fusions are considered to be the most challenging in routine contract laboratories. The high amount of dissolved solids in such matrices often requires re-runs due to drift in signal from the slow build up of salts. In the example below, the use of the Elegra shows virtually no variation in internal standard signal over a period of 4 hours.
