Measurement of Trace Elements in Naphtha Using Ultrasonic Nebulization / Membrane Desolvation with ICP-AES Detection - Application Note

Measurement of trace elements in volatile organic solvents with ICP-AES detection is difficult for several reasons: plasma instability and/or failure, carbon buildup on the ICP torch, and spectral interferences from carbon emission background. A specialized sample introduction accessory can reduce organic-solvent based interferences and enhance trace element detection using a combination of ultrasonic nebulization and membrane desolvation.
