What is the difference between relative retention time and retention time?
Retention time is the time it takes for a compound to travel from the injection point to the detector in chromatography. Relative retention time is the ratio of the retention time of a compound to that of a reference compound in the same chromatographic system. It is used for comparing the behavior of different compounds on the same chromatographic column.
What is the retention time of CACO3 with H3PO4?
The retention time of CaCO3 with H3PO4 can vary depending on the specific experimental conditions such as the solvent, temperature, and column type. Generally, CaCO3 has a shorter retention time compared to H3PO4 due to differences in their chemical properties and interactions with the stationary phase in chromatography. It is advisable to perform a chromatographic analysis to determine the exact retention time for this specific interaction.
Why are estuaries vulnerable to the effects of pollution?
Estuaries are very productive ecosystems because they constantly receive fresh nutrients from the river and from the ocean. The surrounding land, such as the mainland or a peninsula, protects estuaries from the harsh force of ocean waves.
Is an estuary warm or cold?
An estuary can have varying temperatures depending on the region and time of year. Generally, estuaries tend to have fluctuating temperatures due to the mixing of freshwater and saltwater, which can create a range of temperature conditions from warmer to colder.
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.
What is the Retention factor of caffeine?
it depends on the retention time, void time and reagents that you were used on your chromatograph.
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
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
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.
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.
