Creating/Editing Interference Correction Equations

Interference correction equations, if used in your method, should be edited prior to
setting the acquisition parameters. This will ensure that all masses necessary for the
interference corrections will be acquired. ChemStation enables you to modify or edit
the Interference Equation. Interference Equations are very effective for elements
that are subject to interference from polyatomic ions, and elements that only have
one isotope, such as
To edit and modify the interference equation, complete the following steps:
1 Select Methods>>Edit Interference Equations.
The Interference Equation dialog box appears. If no interference correction
equations have been entered, the Interference Equation panel displays the message
"No interference equation has been edited".
2 Display interference correction equations.
• When the Show All Mass Numbers box is checked, all interference correction
equations are displayed.
• When a library is selected in the drop-down list box, the interference correction
equations in the library are displayed.
The libraries below exist as defaults.
• EnvNoORS: Library for general environment analysis (for non-ORS models)
• EnvORS: Library for general environment analysis (for ORS models)
• EPA200.8: Library for EPA200.8
• EPA6020: Library for EPA6020
• FoodORS: Library for food analysis (for ORS models)
