GC-MS Ion Ratio Confirmation - Qualifier and Identifier Ion Techniques

In GC-MS we can use qualifier and quantifier ions to more confidently identify and quantify our analytes. Ion ratio confirmation takes qualifier ions a step further by specifying a limit on the ratio of peak areas obtained by qualifier ions, providing a greater qualitative assurance of the identity and specificity of the peak used for quantitation. This module will discuss these techniques and demonstrate how to implement them.

Topics include:

• Qualifier ions
• Quantifier ions
• Ion ration confirmation (IRC)
