“…(6) Because MAr+ correction can be done, Zr, Nb, or Mo determination in steel may be possible, using quadrupole mass analyzer based GDMS. (7) This approach of MAr+ correction can be applied to other materials in order to overcome the general problems of GDMS interferences.…”

Determinations of low-level Zr, Nb, and Mo in steel samples by glow discharge mass spectrometry are described. The possibilities of metal argide correction on the isotopes of those elements and the use of doubly charged ions are discussed. Selection of suitable isotope(s) depends on the major and minor constituents of the sample. Correction of metal argide interferences MAr+, where M is Fe, Cr, Mn, or Ni, can generally be made by monitoring the ion intensities of the M+ and production rate of FeAr+/Fe+. Use of doubly charged ions for Zr, Nb, and Mo determination is not feasible because of the existence of doubly charged metal argides such as FeAr2+ or low intensities of the doubly charged analyte ions.Recently the requirements for trace analyses for high-purity iron as well as low-alloy steels, which are based on high-purity iron, have been increasing. Traditionally, a variety of analytical methods are applied for the determination of major and trace elements in steels, such as atomic absorption spectrometry (AAS),1 inductively coupled plasma atomic emission spectrometry (ICP-AES),2 X-ray fluorescence spectrometry (XRF),3 or spark emission spectrometry (SES).4 Those methods are well established, and numerous papers were published discussing specific analytical problems. AAS and ICP-AES are good for quantitative analysis with good sensitivities. AAS especially has a superior sensitivity for specific elements, and ICP-AES has the capability of multielement analysis. Both of these methods, however, usually require time-consuming acid-decomposing procedures because of liquid-state sample introduction. It is also difficult to analyze gas components with them. On the other hand, XRF and SES do not require wet chemistry. XRF is good for quantitative analysis, but its sensitivity is somewhat poor. SES is widely used for steel analysis because of its wide-range coverage of the elements and good sensitivity, but it is poor in quantitative analysis.Glow discharge mass spectrometry (GDMS) has been utilized recently for the determination of trace-to ultra-tracelevel impurities in high-purity metals or semiconductors.

GDMS is based on a glow discharge ion source, which generates ions through sputtering (cathodic sputtering) of a solid surface and ionisation (electron impact or Penning ionisation) by a glow discharge plasma. A glow discharge plasma is formed by the passage of an electric current through a low-pressure gas. The ions are separated in a mass spectrometer and finally recorded at a detector. GDMS is a method for the direct determination of trace elements in solid states providing traceelement information of solid samples. Beside the direct current (DC) mode, analytical glow discharges can also be operated in a radiofrequency (RF) mode, most often applied for analysis of nonconducting samples (Figures 13.1 and 13.2).

“…For the determination of composition as well as trace impurities in metal and alloys, glow discharge mass spectroscopy (GD‐MS), laser ablations inductively coupled plasma mass spectrometry (LA‐ICP‐MS) are generally employed. [ 1,2 ] However, the systems are highly expensive and require the availability of solid metal calibration standards containing the trace elements of interest as the sensitivity of the elements is strongly dependent on matrix. In addition, the mass analyzer in the system should have high resolution to get rid of the isobaric interferences.…”

TXRF spectrometry has been utilized for the determination of impurities in copper metal. Multielement standard solution has been used for the calibration of TXRF spectrometer. To avoid the matrix effects, Cu was separated by electrochemical separation method under optimized condition followed by determination of impurities using TXRF. K, Ca, Fe, Ni, and Zn are the impurities found to be present in copper metal. Bottom up approach was employed to get the measure of the combined uncertainty in the results. The uncertainty associated with the recovery of electrochemical separation process is the highest. The TXRF results were validated by analyzing the same sample using ICP‐OES. Student's t‐test was performed to establish the statistical indistinguishability of the results obtained from TXRF and ICP‐OES.
