The aim of this study was to develop a fast, quantitative method for the determination copper tetramibi tetrafluoroborate active substance content in POLATOM’s PoltechMIBI kit before radiolabeling, using inductively coupled plasma optical emission spectrometry (ICP-OES). Copper is key complex that after radiolabeling with sodium pertechnetate [99mTc], forms technetium [99mTc] sestamibi used primarily detection myocardial perfusion abnormalities. Indirect determines Cu developed and validated...
A new sandwich sensor, consisting of an O 2 planar optode overlain by a thin (90 µm) DGT layer is presented. This sensor can simultaneously resolve 2‐D dynamics and trace metal fluxes in benthic substrates at high spatial resolution. The accumulates metals on small particle size (0.2 chelating resin records the locally induced flux during deployment, whereas resolves dynamic near real time same location sediment. Despite its ultrathin composition, has carrying capacity for with no saturation...
Environmental context. Modelling of discrete sites diagenesis in sediments (microniches) has typically been performed 1-D and involved a limited set components. Here we present new 3-D model for microniches within traditional vertical sequence redox reactions, show example modelled niches range sizes, close to the sediment–water interface. Microniche processes may have implications understanding trace metal diagenesis, via formation sulfides. The provides quantitative framework examining...
Environmental context. Observations, using the technique of diffusive gradients in thin-films (DGT), pronounced, small-scale (millimetre) maxima concentrations sulfide and metals pore water sediments, have emphasised importance processes occurring microniches. Modelling interactions between microniche sources DGT devices within a sediment environment demonstrates how these sharp features arise provides basis for their quantitative interpretation. Abstract. Measurements sediments made...
