Chromatographic Summary
Summation of the intensities of all detected ions at each point in time during a mass spectrometry run produces a visual record of the entire sample composition. Examination of the total ion chromatogram allows a chemist to see every detectable component that elutes from a gas or liquid chromatography column. This profile acts as a primary map for identifying unknown additives in a textile finish.
Component Identification
Peaks on the timeline represent different chemical substances as they exit the instrument. In a total ion chromatogram, the height of each peak corresponds to the abundance of the substance, although specific ion monitoring is needed for precise quantification. It provides a quick assessment of sample complexity and purity.
Diagnostic Utility
Internal diagnostic teams use this output to compare a current production batch against a master standard. A total ion chromatogram that shows unexpected peaks indicates contamination or a change in the chemical formulation. This screen is effective for detecting unreacted monomers or residual solvents.
Software Processing
Software algorithms integrate the area under each peak to calculate the relative proportions of the constituents. A clear total ion chromatogram simplifies the process of deconvolving complex spectra from multi-component fabric finishes.
