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 will be the effect of pH on retention time?
Retention time decrease with an increase in pH.
How do you determine the ratio of ions in a compound?
subscripts
How to determine stability of a ion or compound in water?
To determine the stability of an ion compound in water: look up the product solubility constant (Ksp) for the compound to be dissolved; write the chemical equation and modify the Ksp equation.
How can bonding determine the properties of a compound?
i dont know !! :P

Why the retention time will decrease if the polarity of mobile phase increase in normal phase HPLC?
because in normal phase HPLC mobile phase is non polar and stationary phase is polar. Most of the compound of interest are polar, if you increase the polarity of mobile phase compound of analyte will stay in mobile phase and will elute faster and retention time will be shorter.
What will be the effect of pH on retention time?
Retention time decrease with an increase in pH.
Retention time in Hplc?
The Time-Taken the sample Or elute in the column is called the retention time in hplc.
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
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 difference between retention time and detention time?
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
