Prospects in Analytical Atomic Spectrometry
Tendencies in five main branches of atomic spectrometry (absorption,
emission, mass, fluorescence and ionization spectrometry) are considered. The
first three techniques are the most widespread and universal, with the best
sensitivity attributed to atomic mass spectrometry. In the direct elemental
analysis of solid samples, the leading roles are now conquered by laser-induced
breakdown and laser ablation mass spectrometry, and the related techniques with
transfer of the laser ablation products into inductively-coupled plasma.
Advances in design of diode lasers and optical parametric oscillators promote
developments in fluorescence and ionization spectrometry and also in absorption
techniques where uses of optical cavities for increased effective absorption
pathlength are expected to expand. Prospects for analytical instrumentation are
seen in higher productivity, portability, miniaturization, incorporation of
advanced software, automated sample preparation and transition to the
multifunctional modular architecture. Steady progress and growth in
applications of plasma- and laser-based methods are observed. An interest
towards the absolute (standardless) analysis has revived, particularly in the
emission spectrometry.Comment: Proofread copy with an added full reference list of 279 citations. A

Total antioxidant capacity of biological fluids for chronic kidney insufficiency using coulometric titration data
Express coulometric method for estimation of blood and plasma antioxidant capacity based on the use of electrogenerated compounds of bromine is proposed. Using this method we found changes in total antioxidant capacity in patient with chronic kidney insufficiency during hemodialysis session and after it
