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.
Retention time decrease with an increase in pH.
Using isocratic retention parameters, the gradient elution retention time for several proteins has been calculated. The gradient retention time calculation is based on fitting the isocratic retention data to an equation of the form: log k′ = m log (1/[Ca2+]) + log K and on applying well-established principles of gradient elution. A good correlation between the observed and calculated retention times for several test proteins was obtained at various total gradient times and column flow-rates.Conversely, isocratic retention parameters characterizing protein retention can be calculated from gradient elution retention data. However, even with retention data of high quality, small errors are amplified by the log-log nature of the ion-exchange isocratic retention model employed.Based on the close correlation between predicted and observed gradient retention times, no evidence for protein denaturation resulting from immobilization of the protein at high initial k′ values at or near the column inlet was observed.

concentration of buffer effects in buffer strength
Genuine is something that has been created first time while orginal is created after genuine
No
Retention time is the time of passing material 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 drum
In HPLC RRT means Relative Retention Time and RRF is Relative Response Factor
Okay, darlin absolute time is the time exactly, like the absolute time is 9:33. Relative time is rounded basically, you probly hear people say its relatively 'round 9:30. Hope that helps.
-The effective refractory period is the time in which the cell is incapable of responding to a second stimulus between the phases of 0-3.5, while the relative refractory period is the time in which the cell is making preparations to receive stimulus between phase 3.5-4.
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 decrease with an increase in pH.
Humidity is the amount of water vapor at any given time and relative humidity is the amount of water vapor in the air compared to the greatest amount it can hold at that air temperature.
There is no time difference between them.
The Time-Taken the sample Or elute in the column is called the retention time in hplc.
it depends on the retention time, void time and reagents that you were used on your chromatograph.
The retention time represents the time it takes to an analyte to pass from the column inlet to the detector.
