Improved Trace Element Detection Limits for Water Analysis using Ultrasonic Nebulization with ICP-AES Detection - Application Note

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, thereby extending the lower detection range of ICP-AES. Setup of the U5000AT+ USN takes only 5 to 10 minutes and no computer software is required for operation; samples can be conveniently introduced to the USN via an autosampler.
