An Infrared-Heated Sample Introduction System For Inductively Coupled Plasma Mass Spectrometry
This work involves heating the entire commercially available sample introduction system on a Varian 820MS instrument with off-the-shelf infrared heaters. This heating improves sensitivities by a factor of 2 to 16 times, with high mass elements receiving the greatest improvement. It also improves detection limits by a factor of 1.1 to 3.5 times for most analytes. At the price of doubled oxide formation, the formation of doubly charged species was decreased by a factor of 3. The Be/Li signal ratio, an indicator of plasma robustness, increased from 0.174 to 0.235 with infrared heating. The infrared-heated system enabled the accurate analysis of a drinking water standard reference material (SRM) (for Be, Mg, Al, Cr, Mn, Co, Cu, Zn and As) and of a waste water SRM (for Be, Mg, Cr, Mn, Co, Cu, Zn, Cd, and Pb) by simple external calibration.
期刊介绍:
The ATOMIC SPECTROSCOPY is a peer-reviewed international journal started in 1962 by Dr. Walter Slavin and now is published by Atomic Spectroscopy Press Limited (ASPL). It is intended for the rapid publication of both original articles and review articles in the fields of AAS, AFS, ICP-OES, ICP-MS, GD-MS, TIMS, SIMS, AMS, LIBS, XRF and related techniques. Manuscripts dealing with (i) instrumentation & fundamentals, (ii) methodology development & applications, and (iii) standard reference materials (SRMs) development can be submitted for publication.
