“…Today there are many methods for elemental analysis of different biological samples. Atomic absorption spectrometry (AAS), inductively coupled plasma atomic emission (ICP-AES), and mass spectrometry are usually used for analysis of blood and animal tissues [11, 12]. These methods generally require matrix destruction with concentrated acids.…”

Background. Many biological processes are performed by different protein complexes. During the association of proteins and enzymes forming specific complexes, the latter can include ions of various metal ions, which may be important for their formation and biological function. Objective of the Studies. However, to date in the literature there are no data on metal ions that are part of any protein complexes. Methods. A very stable multiprotein complex (~1000±100 kDa) was separated from other proteins of nine samples of female milk by gel filtration on Sepharose 4B. The content of microelements in the stable multiprotein complex and milk was analyzed using two-jet plasma atomic emission spectrometry. Results. The content of different elements in milk on average decreased in the order: Ca>P>Mg>Al≥Zn≥Fe>Cu >B (0.76–3500 μg/g of dry milk powder), while the content of some elements was very low (Sr>Mn>Cr>Ba>Pb>Ag>Ni>Cd, <0.03–0.5 μg/g). The content of eight elements in stable multiprotein complex was 1.2-9.6-fold higher than in milk and increased in the order: Ca≈Mg<P<Al<Fe<Pb<Ba<Cr<Cd<Zn, while content of SPC eight metals was 12.3-110-fold higher: Cu (12.3)>B (19.7)>Ag (28.7)>Ni (38)≥Sr (110). Conclusions. The analysis of the relative content of sixteen elements in human milk and oligomeric complexes of proteins was performed for the first time. Data on the content of metals indicate that during the formation of protein which associates the increase in the content of metal ions bound with proteins of the complex can occur. Such metal ions can be important for the formation and biological function of protein complexes.

“…A regular review of developments in atomic spectrometry methods for clinical analysis is available. 13 The measurement of Ti by conventional Q-ICP-MS is affected by a range of polyatomic and isobaric interferences, 14 all low abundance and either affected by significant polyatomic or isobaric interferences. This necessitates the use of an instrument with a collision or reaction cell for the removal of the polyatomics, which would have an impact on the ion transmission of the low concentration and low abundance Ti isotopes.…”

Background Patients with metal-on-metal hip replacements require testing for cobalt and chromium. There may also be a need to test for titanium, which is used in the construction of the femoral stem in total hip replacements. It is not possible to use quadrupole inductively coupled plasma mass spectrometry due to interferences. Methods Titanium was measured using inductively coupled plasma optical emission spectroscopy using the emission line at 336.1 nm and Y (internal standard) at 371.0 nm. Internal quality control materials were prepared for blood and serum and concentrations assigned using a sector field-inductively coupled plasma mass spectrometer. A candidate whole blood certified reference material was also evaluated. Results The method had detection and quantitation limits of 0.6 and 1.9 µg/L, respectively. The respective bias (%) and measurement uncertainty ( U) (k = 2) were 3.3% and 2.0 µg/L (serum) and - 1.0% and 1.4 µg/L (whole blood). The respective repeatability and intermediate precision (%) were 5.1% and 10.9% (serum) and 2.4% and 8.6% (whole blood). The concentration of titanium was determined in patients' samples, serum (median = 2.4 µg/L, n = 897) and whole blood (median = 2.4 µg/L, n = 189). Serum is recommended for monitoring titanium in patients, since the concentration is higher than in whole blood and the matrix less problematic. In hip fluid samples, the concentrations were much higher (mean 58.5 µg/L, median 5.1 µg/L, n = 83). Conclusions A method based on inductively coupled plasma optical emission spectroscopy was developed and validated for measuring titanium in clinical samples.

“…It is frequently utilized in water distribution networks. 3,5,7,8 The drawback of this procedure is that possible contamination from the surrounding atmosphere can adsorb on the surface after sample preparation (during drying and sample transfer to the spectrometer). 2 To study corrosion inhibitor surface phenomena highly sensitive surface analytical techniques are required, as the corrosion inhibitor surface layer thickness is usually only a few monolayers thick.…”

The focus of this article is a detailed surface analytical study by X-ray photoelectron spectroscopy (XPS) of 4-methyl-2-phenyl-imidazole (MePhI) adsorbed from 3 wt.% NaCl solution on a Cu surface. It is shown for the first time that MePhI is a Cu corrosion inhibitor in chloride solution after short-term (1-100h) and long-term immersion periods (180 days), and that MePhI is an anodic-type corrosion inhibitor. Surface analysis was first performed by examination of the Cu surface layer chemical structure, followed by surface layer thickness analysis according to the Tougaard method. It is shown that a very thin layer is formed. Next, a detailed angle-resolved XPS analysis was performed to study the manner of MePhI bonding on the copper surface. It is claimed that the MePhI molecule connects to the surface via C and N atoms. A flat orientation of MePhI molecules, parallel to the copper surface, is suggested.
