Retention time is the time of passing material(fluids) through the volume of the drum with determined flowrate :
Retention time=V/Q
which Q : flowrate
and V : Volume
but Detention time is the time that materials stay in drum
in 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 time
which n is the number of times which materials(fluids) pass through the the volume of drum.

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!
Can relative retention time changed?
No
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.
The retention of encoded information over time refers to?
Storage
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.
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 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
Define retention time?
Retention time refers to the time it takes a solute to travel through the chromatography column. It is assigned to the equivalent solute peak.
Can relative retention time changed?
No
Why does gravity slow down time?
think of it this way gravity is the time so the more gravity the more time. with out gravity there would be no time because of gravity stuff happens. with out time there would be no gravity. so you can think of it as the same think instead of diffrente thinks.
How can you determine retention time of a compound?
HPLC
