For each mass spectral acquisition polarity, two visualizations are presented:<\/p>\n
The TIC is a trace of the summed intensity of all ions as a function of time.<\/p>\n
Note that in runs of complex samples such as these algal exudates, there are so many compounds co-eluting that individual peaks are not observed on the trace. Greater information visualization is possible in the Topological Overview.<\/p>\n
A TIC is available for the\u00a0positive<\/a>\u00a0and\u00a0negative<\/a>\u00a0electrospray mode.<\/p>\n This is a top-down, or bird’s-eye view of the data sets, plotting mass as a function of time, with mass intensity increasing with color intensity.<\/p>\n A topological view is available for the\u00a0positive<\/a>\u00a0and\u00a0negative<\/a>\u00a0electrospray mode.<\/p>\n For the optical absobance acquisition, two types of visualization are presented:<\/p>\n These are various views of\u00a0intensity vs. wavelength vs. time<\/a>.<\/p>\n Two generally diagnostic\u00a0wavelengths<\/a>\u00a0(254 and 290 nm) are presented.<\/p>\nTopological (“Map”)<\/h2>\n
