The physical sense of simulation models of liquid chromatography: propagation through a grid or solution of the mass balance equation Two distinctly different approaches have been used to simulate the movement of bands through a chromatographic column. One example of the first approach is... M Czok...
A mass-balance method for determining the size of the intracellular pool of respiratory metabolism substrates is suggested. It involves registration of the response of starving microorganisms to microamendment by a limiting substrate (glucose). In a continuous Pseudomonas fluorescense culture, the relatio...
Basic equation of chromatographyCorrected retention volumeThe mass balance equation of a chromatographic system using a compressible moving phase has been compiled for mass flow of the mobile phase instead of traditional volumetric flow allowing solution of the equation in an analytical form. The ...
The purity determination of organic calibration standards using the traditional mass balance approach is described. Demonstrated examples highlight the potential for bias in each measurement and the need to implement an approach that provides a cross-check for each result, affording fit for purpose puri...
In a commonly implemented version of the vorticity–velocity formulation, the governing equations for the fluid dynamics are expressed as two Poisson-like velocity equations together with the vorticity transport equation. However, for some flows with large vorticity gradients, spurious mass loss or...
Organic waste products (OWP) application to crop lands makes possible nutrients recycling. However, it can result in long-term accumulation of trace elemen
Analytical methods based on the mass balance approach were developed for the purity evaluation of tetracycline hydrochloride, a representative salt compound used in pure veterinary drug analysis. The purity assignment method was used to quantify individual classes of impurities via independent analytical tec...

The overall measurement uncertainties of this method were much less than one-third of the expected relative standard deviations of testing laboratories, which was estimated by the Horwitz equation (9–11% for the 10–50 mg/kg range), indicating that the developed method has adequate metrological ...
Standard proxies for reconstructing surface mass balance (SMB) in Antarctic ice cores are often inaccurate or coarsely resolved when applied to more complicated environments away from dome summits. Here, we propose an alternative SMB proxy based on photo
