Atomic spectrometry update-X-ray fluorescence spectrometry

X-rays have been used for non-invasive high-resolution imaging of thick biological specimens since their discovery in 1895. They are widely used for structural imaging of bone, metal implants, and cavities in soft tissue. Recently, a number of new contrast methodologies have emerged which are expanding X-ray’s biomedical applications to functional as well as structural imaging. These techniques are promising to dramatically improve our ability to study in situ biochemistry and disease pathology. In this review, we discuss how X-ray absorption, X-ray fluorescence, and X-ray excited optical luminescence can be used for physiological, elemental, and molecular imaging of vasculature, tumours, pharmaceutical distribution, and the surface of implants. Imaging of endogenous elements, exogenous labels, and analytes detected with optical indicators will be discussed.

“…At present, the most relatively accessible techniques for surface analysis include X-ray photoelectron spectroscopy (XPS) (Batrusaitis et al, 2012), scanning electron microscopy combined with energy disperse spectroscopy (SEM/EDS) (Wang et al, 2010) and X-ray fluorescence spectroscopy (XFS) (Howard et al, 2012;West et al, 2011); although these methods are all capable of quantitative analysis of solid samples without the need for organic solvent, their sensitivities are rather low-on the order of a few percentage. Secondary ion mass spectrometry (SIMS), on the other hand, has high sensitivity and detection limits that can reach the level of parts per billion (Gannoun et al, 2011;Cerqueira et al, 2011).…”

“…Surface analysis techniques, which are applied widely in material analysis, appear to be promising analytical routes because they require almost no solvent during the entire analysis procedure.

This paper describes a new analytical method, using a combination of ammonium pyrrolidine dithiocarbamate/methyl isobutyl ketone (APDC-MIBK) microextraction and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), for the determination of the concentrations of Cd and Pb in aqueous samples. Only 200 µL of organic solvent was used throughout the entire analysis process, with enhancement factors as high as 25. Recoveries from replicate analyses of natural water [NIST 1640(a)] containing mean concentrations of 3.1 mg Cd L -1 and 9.3 mg Pb L -1 were 95 ± 3 and 104 ± 4%, respectively. The corresponding detection limits were 0.6 mg L -1 for Cd and 0.9 mg L -1 for Pb. The main advantage of this approach is its simplicity in terms of sample preparation, as demonstrated by quantifying the levels of Cd and Pd in real samples, including tap water, groundwater, and seawater, using a standard addition method.
