Answer / maduru balaram

Rt is identified main peak.
but rrt is identified impurities purpose

rt*rrt-impurities rt is identified

Answer / gangadhar n v

RT is the retention time of Analyte or Impurity.
RRT is the ratio between the Impurity Retention time to Analyte Retention time.
RF means Response Factor.It is the ration between the Impurity Concentration to Impurity Area.
RRF means Releative Response Factor.It is equals to 1/RF. or Slope of the Impurity/Slope of the Analyte.It is findout from the Linearity Curve.RF is Called as Correction Factor.

Answer / 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.
