How to Calculate response factor(RF) & relative response
factor(RRF)?
Answer Posted / 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.
