Response factor, usually in chromatography and spectroscopy, is the ratio between a signal produced by an analyte, and the quantity of analyte which produces the signal. Ideally, and for easy computation, this ratio is unity (one). In real-world scenarios, this is often not the case. See more The response factor $${\displaystyle f_{i}}$$ can be expressed on a molar, volume or mass basis. Where the true amount of sample and standard are equal: $${\displaystyle f_{i}={\frac {A_{i}}{A_{st}}}f_{st}}$$ See more One of the main reasons to use response factors is to compensate for the irreproducibility of manual injections into a gas chromatograph (GC).
