What will be the effect of pH on retention time?

Retention time decrease with an increase in pH.


How do you define the retention value of a chemical species?

The retention value of a chemical species refers to its ability to remain in a specific location or system, often used in the context of chromatography where it indicates how strongly a compound is retained on a stationary phase compared to the mobile phase. This is quantified by the retention factor (k) or retention time, which is calculated based on the time taken for the compound to travel through the column compared to the mobile phase.


Why retention time vary during isocratic analysis?

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.

What is the difference between relative and absolute time?

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.


What is the difference between the effective refractory period and the relative refractory period?

The effective refractory period is the timeframe during which a cardiac cell is completely refractory and cannot respond to any stimulus. The relative refractory period is the period during which a cardiac cell is in a partially recovered state and can only respond to a strong stimulus.


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!
