The pergo 2 Argon Humidifier is for use with ELAN® and NexION® ICP-MS series instruments. The pergo improves performance of all concentric nebulizers for the routine analysis of brines, fusion digests and other high-TDS samples. A high pressure membrane positioned inside a temperature-controlled water reservoir perfuses water vapor into the ICP nebulizer gas stream. By increasing humidity in the argon nebulizer gas, the pergo prevents salt deposits at the nebulizer tip, improving short and long-term signal stability. The pergo 2 is designed for analyses dealing with high concentrations of dissolved solids on instruments using auxiliary gas.
