Sentence examples for concentrations of the background from inspiring English sources

To facilitate the understanding of the progress of a free zone electrophoresis experiment, we have discussed in simple terms how the concentrations of the background electrolytes become rearranged during a run and why the difference between the mobilities of the protein and the mobilities of the background electrolyte determines whether a peak exhibits fronting or tailing.

The ACCORD Lipid trial tested the hypothesis that treatment of patients with type 2 diabetes with fenofibrate to increase plasma HDL cholesterol levels and reduce plasma TG concentrations, on the background of simvastatin therapy, would result in additional cardiovascular benefit compared with simvastatin therapy alone (7).

The factors studied were pH, concentration of methyl-β-cyclodextrin, concentration of the background electrolyte and percentage of acetonitrile as organic modifier.

During the optimization of these CE methods, the concentration of the background electrolyte (BGE) was found to be crucial to an effective separation.

For calculation of the yield improvement, we compared the final fatty acid concentration of the background strain with the same strain plus deletion or overexpression of the respective gene.

In the second region of the curve, however, the number of MWNT layers increased with increasing concentration, and the direct contact between the inner MWNTs and the analyte solution was weakened by further increasing the concentration of MWNTs; the background current was increased and MWNTs were fallen down in the solution.

The biosensor can be used to measure micromolar concentrations of GDP on the background of millimolar concentrations of GTP.

In brief, the regional, urban, and local contributions of each pollutant were determined and summed to obtain background concentrations (the sum of regional and urban contributions) or overall concentrations (the sum of the background and local contributions) for each participant.

Subsequently, a Design of Experiments (DoE) was used to optimize the pH and concentration of the selected background electrolyte (BGE) containing both TRIS and boric acid.

Concentrations are plotted after subtraction of the background concentrations.

I geo is calculated to estimate the enrichment of metal concentrations above the background level which was proposed by Muller (1969).
