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.

Hello Dear all; I have a technical question related to analytical Chemistry, I have a sample of (40% w/w) Ferric Chloride solution (for water treatment purposes which consist a little portions of Ferrous Chloride and Hydrochloric acid. I need to know the methods to determine the percentages of each Ferrous Chloride and Chloride acid. Also I want to make sure that this solution is truly (40% w/w). So ANY CLUE !!! Thanks in advance.
