Retention time & Relative Retention time Definition &
between difference?
How to Calculate response factor(RF) & relative response
factor(RRF)?

Answer Posted / aruna

rt is a respective compound retention time, rrt means imp rt/main peak rt.
Response factor like rt, rrf means slop of imp/slope of the api, through linearity curve we find out the rrf.
