How to calculate Relative retention time?
Divide the retention time of the peak of ineterest (ex. 14.8 min.) by the retention time of the main peak (ex. 15.9 min.) 14.8/15.9 = 0.93 Therefore your RRT is 0.93 Remember, any peak with an RRT <1 elutes before the main peak, and any peak with an RRT >1 elutes after the main peak! What is RRT & RRF in hplc
Retention time in Hplc?
The Time-Taken the sample Or elute in the column is called the retention time in hplc.
Are there any advantages in increasing retention time?
The retention time would increase becasue longer distance would be travelled by the analyte!
What is diffrente of retention time and ditention time?
Retention time is the time of passing material(fluids) through the volume of the drum with determined flowrate :Retention time=V/Qwhich Q : flowrateand V : Volumebut Detention time is the time that materials stay in drumin batch systems Detention time equals with Retention time.but in continious systems or semi batch systems denention time is bigger than Retention timecommonly.Detention time= n Retention timewhich n is the number of times which materials(fluids) pass through the the volume of drum.
What is the effect of flow rate on retention time in HPLC?
When you increase the flowrate of the carrier gas, the retention times decrease. Just like when you increase the temperature of the column. Both of these conditions are sometimes necessary for substances that would otherwise have very long retention times.
What is the difference between relative retention time and retention time?
the difference between retention time and retention factor is that the retention time is a quatitative value where`s the retention factor is a qualitative on.
What is RRT and RRF in hplc?
In HPLC RRT means Relative Retention Time and RRF is Relative Response Factor
What will be the effect of pH on retention time?
Retention time decrease with an increase in pH.

What is the Retention factor of caffeine?
it depends on the retention time, void time and reagents that you were used on your chromatograph.
What does retention time mean?
The retention time represents the time it takes to an analyte to pass from the column inlet to the detector.
Which great lake has the shortest retention time?
Lake Erie has the shortest retention time of about 2.7 years
How do you define the retention value of a chemical species?
The Retention Value(Rf) of a chemical species is the relative distance a particular component moves in relation to the distance the solvent front moves.
Are there any advantages in increasing retention time?
The retention time would increase becasue longer distance would be travelled by the analyte!
