This application note describes the use of the Teledyne CETAC U5000AT+ Ultrasonic Nebulizer (USN) with ICP-AES detection for enhanced measurement of trace elements in a natural water sample. Ultrasonic nebulization offers improved element transport efficiency to the ICP versus the conventional pneumatic nebulizers that are standard kit with ICP-AES instruments, ...
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 ...
This application note will examine the use of an efficient ultrasonic nebulizer (USN) with ICP-AES to improve trace element detection in a 7.5% high-purity sulfuric acid matrix. Elements of interest include Al, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Ti, W, Zn, and Zr. A particular goal is to lower instrument detection limits (IDLs) below 0.1 μg/L ...
