Performing a Quantitative Analysis
1 Select the Table tab on the Edit Calibration dialog box.
Table Tab
The Analyte table shows the tune step, mass, and element symbol of each element
for which a calibration file has been created. This table allows the setting of the
curve fit, ISTD, weight, minimum concentration, units, and concentration values of
levels. Each level is indicated with the name of the data file set on the Standard
Files tab screen.
The ISTD table shows the tune step, mass, and element symbol of the element
subject to ISTD correction and VIS correction. This table allows the setting of the
VIS, units, and concentration values of levels.
When you click the right mouse button with the mouse pointer positioned on a table,
a popup menu appears to let you rearrange the table order by step, mass, or element;
copy or paste a field; delete an element; set a concentration factor; or display the
Graph (Detail) tab screen.
2 Click and select the field of the desired level to input a concentration value.
Click on a field and drag the cursor to select two or more continuous fields in a
vertical direction. Click on a column title to select all the fields in that column.
The scroll bar in the lower right section enables scrolling of the level display.
3 Enter a concentration value.
To set a standard addition calibration, the concentration of the background (bkg) file
must be set to bkg or -1 for all elements. The concentration of an unspiked standard
sample should be set to 0 for all elements.
