“…Over the years, many different analytical techniques have been used for the analysis of ultra-high-purity metals. These include graphite-furnace atomic absorption (GFAA) [1], inductively coupled plasma optical emission spectroscopy (ICP-OES) [2], neutron activation analysis (NAA) [3], and glow-discharge mass spectrometry (GDMS) [4]. Recently, however, the demand has been for higher-purity metals.…”

Inductively coupled plasma mass spectrometry (ICP‐MS) has become the technique of choice for trace elemental analysis recently. Much work has focused on direct solid‐sample introduction techniques for ICP‐MS, with laser ablation (LA) showing the most promise. Photographs taken of the LA craters are used to demonstrate independent optimization of the ablation event. The type of optimization used will depend on the individual analysis requirements. An axial time‐of‐flight (TOF) mass spectrometer is used in conjunction with the ICP for the direct analysis of metals. Using this combination, inhomogeneities of specific trace metals (Nd, Zr, and Ta) in certified standard reference materials were found, while other metals remained homogeneous. These results are confirmed using steady‐state scanning of the sample and individual spot analysis.

A pulsed Nd:YAG laser operating on the second harmonic wavelength at 532 nm was used in this work. The influence of sample surface topography on spectral emission of laser-produced plasmas was investigated. Stainless-steel samples with different grades of surface polishing (range 0.026-4.54 µm) were prepared and analysed using LIBS. The effect of surface roughness on analytical precision was found to be dependent on laser beam energy, with optimum results for beam irradiances in the range 28-57 GW cm −2 . The reproducibility of spectral emission for pre-ablated surfaces also has been investigated. Limits of detection of molybdenum in stainless steel at different sample finishes and for several laser irradiances are discussed.
