AnalyzeFractions

AnalyzeFractions[chromData]⟹pickedSamples

selects fractions from a given chromatograph to be carried forward for further analysis.

AnalyzeFractions[chromProtocol]⟹pickedSamples

analyzes all data in the given protocol.

AnalyzeFractions[collectedFracs]⟹pickedSamples

uses the given set of fractions as a starting point for the analysis, instead of starting by filtering based on peaks.

Details

The selection process first filters using the Peaks options, then filters against the Exclude option, and finally filters on the Include option.

Basic Examples (3)

Pick fractions from a data object:

Take an HPLC protocol as input:

Plot picked fractions:

Additional Examples (2)

Pick fractions from a data object (using the Fractions field):

Given list of chromatography datas:

Options (14)

Domain (1)

Domain can also be specified with time units:

Exclude (3)

Exclude the fraction overlapping 28.5:

Exclude the 10th fraction from the FractionsCollected list:

Exclude the fraction overlapping 26 minutes and the second fraction:

Include (3)

Include the fraction overlapping 22.5:

Include the second fraction from the FractionsCollected list:

Include the second fraction and the fraction overlapping the 26 Minute mark:

OverlappingPeaks (2)

Return only fractions overlapping the biggest peak:

If no peaks are specified, then no selecting is done based on peaks. In this case all collected samples are returned:

Template (1)

Use options from previous fractions analysis:

TopPeaks (4)

By default, uses only the largest (by area) peak:

Use the 2 largest peaks:

Use TopPeaks->All to use peaks:

Use TopPeaks->0 to use no peaks:

Messages (1)

InvalidPosition (1)

Positions to Include or Exclude cannot be greater than the number of collected fractions:

Possible Issues (1)

Include option overrides Exclude option because of the order in which the filtering occurs:
