Displaying Fraction Collection Results — the
Fractions Table

Like the Traces table, the Fractions table is available when the run is opened in the

Evaluation window. The Fractions table is available only when a single run is open in

the Evaluation window. It is not displayed for multiple run analyses or for trace

comparisons.

The following fields are displayed for each fraction collected:

# — sequential row number.

Rack/Tube — the rack and tube number of the fraction.

Tube location — the location of the tube in the plate or rack based on its

numbering scheme.

Start — the beginning of the collection, displayed in the units of the

currently displayed x-axis.

End — the end of the collection, displayed in the units of the currently

displayed x-axis.

Collected volume (ml) — the total fraction volume collected in that tube.

Area (ml*mAU) — the area of the fraction between the UV trace selected

in the heat map and its baseline. This column appears after peak

integration is performed.

Amount (mg) — the amount of protein in the fraction based on the trace

selected in the heat map. This column appears after peak integration is

performed and the extinction coefficient value is entered into the table.

Concentration (mg/ml) — the calculated concentration of the protein for

the specified fraction based on the trace selected in the heat map. This

column appears after peak integration is performed and the extinction

coefficient value is entered into the table.

Relative area (%) — the relative fraction area of all fraction areas in a

trace. This column appears after peak integration is performed.
