3, the peak retention time of solvent methanol was 2.43 min, and the peak retention time of isopropanol was stabled at 2.78 min with symmetrical peak shape.
The standard solvent of 75% methanol solution was used to test several other water-soluble compounds, including ethanol, acetic acid, and acetone.
What is the retention time of acetone?
The standard retention time for acetone is 5.23 min.
What is the retention time of octane?
The retention time for octane is 14.1 min.
The retention time for nonane is 21.5 min.
The retention time for unknown molecule is 17.5 min.
The retention index for octane is 800.
What is retention time in HPLC?
Retention time is the time that a solute spends in a column or it can be defined as the time spent in the stationary and mobile phases.
The longer retention time depends on the interaction of the analyte with the stationary phase.
The stronger the interaction, the more will be the interaction time.
