\n\t\tAnalytical Results\n\t<\/h1>\n\t

Chromatographic Overviews<\/h3>\n

Mass Spectral<\/h3>\n

For each mass spectral acquisition polarity, two visualizations are presented:<\/p>\n

Total Ion Chromatogram (“TIC”)<\/h3>\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

Topological (“Map”)<\/h3>\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 ia available for the\u00a0positive<\/a>\u00a0and\u00a0negative<\/a>\u00a0electrospray mode.<\/p>\n

Optical (UV-Visible)<\/h3>\n

For the optical absobance acquisition, two types of visualization are presented:<\/p>\n

3D<\/h3>\n

These are various views of\u00a0intensity vs. wavelength vs. time<\/a>.<\/p>\n

Specific Wavelength<\/h3>\n

Two generally diagnostic\u00a0wavelengths<\/a>\u00a0(254 and 290 nm) are presented.<\/p>\n

Compound Summary Table<\/h3>\n

A\u00a0table<\/a>\u00a0showing potential retention-time \/ molecular weight pairs, and their molecular ions as determined by the “mzMine” program ( see “http:\/\/mzmine.sourceforge.net” for more information on this program).<\/p>\n\n","protected":false},"excerpt":{"rendered":"
