In our study, the methods of separation free metal ions from mixture were reviewed first, including gel filtration chromatography, organic solvent precipitation, ion exchange chromatography, membrane separation and high performance liquid chromatography. Then, the qualitative analysis methods of chelates ...
A quick method for separating mixtures of metal ions, amino acids, carbohydrates, colors, and pharmaceuticals is paper chromatography (PC). For this qualitative analysis, only a very small sample is needed. Metal cation separation has seen increased by the use of the PC approach. Here, the ...
Different characterization methods for describing structure of humic substances is given in this overview. The application of different analytical methods for the qualitative and quantitative characterization of HS, including physi-cal/chemical analysis (elemental analysis, acid/base titration, potentiometer ti...
Corrosion analysis using test copper bars (recommended, low cost but long term and low precision) According to the ISAS71.04-1985 standard, perform a qualitative assessment on the corrosive gas in the environment. The environment result can be obtained after one month. Inspection report from a th...
RP-HPLC and non-aqueous CZE methods were evaluated for qualitative and quantitative analysis of esterified macrocyclic compounds of the DOTA family (DOTA=1,4,7,10-tetraazacyclododecan-1,4,7,10-tetraacetic acid). This group of compounds represents important reaction intermediates in synthesis of magn...

this requires coordinate precision that is not provided by either the AlphaFold or the AlphaFill models (even after optimization). Hence, the models should be interpreted in a qualitative manner. Moreover, in some cases ligand interactions involve parts of the protein that are not modeled with hi...
The above-described nucleic acid-based diagnostic methods can provide qualitative and quantitative information to determine whether a subject has a disease characterized by cancer or the effectiveness of a cancer treatment. An increased expression or presence of HERV-WL in a biological sample from a ...
In recent decades safety of food has played a pivotal role from raw material till it reaches the consumer. The food consumed may contain unwanted contaminants, which may impose severe health implications on the consumers. Instrumental techniques like HPLC, GCMS, LCMS, AAS, FTIR, and NIRS detect...
