Standard volumes will have the default names S1, S2, and so on, based on the
sequence of their creation.
To review the regression curve
Open the Standard Curve window and select the Volume Standard Curve tab.
Regression Methods
Three regression methods are available to generate the volume quantification curve
used for absolute quantity: linear, point-to-point, and cubic spline. To display the
standard curve, click the Standard Curve button on the toolbar and select the
Volume Standard Curve tab in the Standard Curve dialog box. See
to learn how each of these methods is calculated.
The data for volume standards are found in the Absolute Quantity column of the
Volume Table.
Note:
Selecting the Force Through Origin checkbox always starts the standard
curve graph at 0,0, regardless of the best curve fit.
Alignment
Align volumes by using the appropriate alignment button. To select several volumes,
Ctrl-click each one, then select one of the alignment buttons. Hover over any of the
six alignment buttons to display its function (Align Left, Align Right, etc.)
Copy and paste selected volumes by pressing Ctrl+C to copy. Press Ctrl+V to
paste.
When you click the Standard Curve button on the toolbar, a chart displays all
unknown and standard quantities.
