hai i am lakshminarayana , can i know the purpus of response factor in gc and how to calculate response factor in gc
The response factor for any analytical instrument is simply the ratio of the response from the instrument to the concentration or mass that produced that response.
RF = peak area/concentration injected (or you can use peak height, or mass injected)
Response factors are used to calibrate the response of the instrument. If you know the RF for a compound, and you measure the response (area or height), you can then calculate the concentration (or mass) that was injected.
