Occurrence and geochemistry of radium in water from principal drinking-water aquifer systems of the United States

Zoltan Szabo, Vincent T. dePaul, Jeffrey M. Fischer, Thomas F. Kraemer, Eric Jacobsen
2012 Applied Geochemistry  
The most common occurrence of elevated Ra throughout the USA occurred in anoxic water (low dissolved-O 2 ) with high concentrations of Fe or Mn, and in places, high concentrations of the competing ions  ...  Activity ratios of 224 Ra/ 228 Ra in the water samples were mostly near 1 when concentrations of both isotopes were greater than or equal to 0.037 Bq/L (1 pCi/ L), the level above which analytical results  ...  The resulting disparity in performance is a limitation of the analytical approach.  ...

Purification of antibodies through convective chromatography

Eleonora Lalli
2018
The performance of regenerated cellulose membranes functionalized with two affinity ligands were studied; the commercial A2P ligand and the new recently synthesized HPTA were used to replace Protein A.  ...  However, this method suffers from several limitations, such as high pressure drops across the column, compaction of the granular porous bed and low diffusivity between the particles.  ...  Preliminary tests were performed to optimize the immobilization protocol, the experimental conditions, the analytical techniques used and to assess the HPTA ability to bind the protein of interest, IgG  ...

2021 Naunyn-Schmiedeberg's Archives of Pharmacology  
Testing of substanceinduced disruption of HPTA is routinely done using animal studies.  ...  However, some enzymes remain still uncovered by the analytical spectra of those methods.  ...  Quantification was performed by peak area method. A weighted (1/x) regression first order was performed to determine the concentration of the analytes.  ...

Moreover, much of these studies have been performed by physicists who neglected to fully characterize the materials they were measuring on.  ...  Mattson et al. (1985) had difficulties in obtaining pure Lewis base adducts of [Eu(fod) 3 ], due to the high solubility of [Eu(fod) 3 ] in the usual organic solvents and the tendency of the corresponding  ...  High-molecular weight heterometallic precursors have the disadvantage of low volatility, but this can be overcome by performing the MOCVD process under ultra-high vacuum.  ...
