Total ion intensity
The ionic strength of a solution is a measure of the concentration of ions in that solution. Ionic compounds, when dissolved in water, dissociate into ions. The total electrolyte concentration in solution will affect important properties such as the dissociation constant or the solubility of different salts. One of the main characteristics of a solution with dissolved ions is the ionic strength. Ionic strength can be molar (mol/L solution) or molal (mol/kg solvent) and to avoid confu… WebFigure 1 shows typical chromatograms-total ion chro- matogram, base peak chromatogram and extracted ion chro- matogram-of a complex red wine sample (Tempranillo).

We then describe a thermal proton transfer … The total ion current (TIC) chromatogram represents the summed intensity across the entire range of masses being detected at every point in the analysis. The range is typically several hundred mass-to-charge units or more. In complex samples, the TIC chromatogram often provides limited information as multiple … See more A mass chromatogram is a representation of mass spectrometry data as a chromatogram, where the x-axis represents time and the y-axis represents signal intensity. The source data contains mass information; … See more In an extracted-ion chromatogram (EIC or XIC), also called a reconstructed-ion chromatogram (RIC), one or more m/z values representing one or more analytes of interest are recovered ('extracted') from the entire data set for a chromatographic run. The total … See more The selected-reaction monitoring (SRM) experiment is very similar to the SIM experiment except that tandem mass spectrometry is used and a specific product ion of a … See more The base peak chromatogram is similar to the TIC chromatogram, however it monitors only the most intense peak in each spectrum. This means that the base peak chromatogram … See more A selected-ion monitoring (SIM) chromatogram is similar to an EIC/XIC, with the exception that the mass spectrometer is operated in SIM mode, such that only … See more • Mass spectrum See more
