A general model is proposed for interpreting the appearance of sample and system peaks in ion-exchange chromatography with photometric detection. In this theory, a changed fraction of organic acid in the mobile phase resulting from the ion-exchange process with a sample ion migrates through the ...

PEAKS AB Software is a platform for de novo antibody sequencing and the characterisation of modifications and sequence variants by using liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). PEAKS AB software also supports characterisation of PTMs and variants for research discovery and...
Hydrophobic interaction high-performance liquid chromatography of proteins All proteins except albumin and 尾-lactoglobulin were eluted as sharp peaks. The broadening of some protein peaks may depend upon the influence of the eluent of the structure of those proteins. Variations in column temperature ...

In Ion exchange chromatography, what determines whether or not or how strongly an analyte adsorbs to the stationary phase? Interpret the infrared spectrum of methyl m-nitrobenzoate. How do you differentiate between fluorene and acetanilide? Suggest...
What are the differences between band broadening and peak in chromatography? Explain why knowing the limiting and excess reagents at each point on the titration curve is important. Explain why there exists a correlation between electrostatic potential and acid strength...
Recent publications have described well the development, operating principles, optimization and applications of the ion trap as a mass spectrometer [8], [9]. Many mass spectrometric analyses, especially those utilizing chromatography, air sampling and gas phase reaction monitoring, must be performed ...
