The capacity factor, k' is the same in all chromatography, except in Micellar Electrokinetic capillary chromatography (MEKC).
k' = (tR - tM)/ tM
Where:
tR = retention time (time between injection and elution)
tM = tR of the unretained species (ie. how long it took for the solution you injected to travel all the way through the length of the column). tM is ALWAYS smaller than tR.
The Capacity factor has been changed officially to the retention factor by IUPAC recently

How will calculate rrf in hplc?
To calculate relative retention factor (RRF) in HPLC, you need to divide the retention time of the compound of interest by the retention time of the reference compound. The formula is RRF = (Retention time of compound of interest) / (Retention time of reference compound). This value helps in comparison and identification of compounds in the chromatogram.
How do you calculate relative responce factor in hplc related substance analysis?
(Target ion area response / Int Std area response) * (Int Std Injection Vol / Target Injection Vol)
What is the use of calculating asymmetry factor in hplc?
The asymmetry factor in HPLC is used to assess the peak shape of a chromatographic peak. It is calculated by dividing the front part of the peak by the back part, providing information on the peak tailing or fronting. A symmetrical peak typically has an asymmetry factor close to 1, indicating good peak shape.
How calculate wire rope load capacity?
Wire rope load capacity can be calculated by considering factors such as the breaking strength of the wire rope, the design factor for the specific application, and any additional safety factors required. The formula typically used is: Load capacity = (Wire rope breaking strength / Design factor) - Weight of the load. It is crucial to consult industry standards and guidelines when determining load capacity to ensure safety and reliability.
What type of species can be separated by HPLC but not by gas liquid chromatography?
mixture of enantiomers can be separated by HPLC
What is RRT and RRF in hplc?
In HPLC RRT means Relative Retention Time and RRF is Relative Response Factor
How you calculate rrf value in hplc methods?
Yes.
What is rs-hplc?
"RS-HPLC method" means "Related Substance HPLC Method".
How you calculate the power factor panel capacity you mean how could calculate the KVAR of your PF panel?
Rephrase your question so that it makes sense.
How do you calculate concentration from peak area in HPLC analysis?
To calculate concentration from peak area in HPLC analysis, you can use the formula: Concentration Peak Area / (Slope x Injection Volume). The peak area is obtained from the chromatogram, the slope is the calibration curve slope, and the injection volume is the volume of the sample injected into the HPLC system.
How do you use resolution factor in HPLC?
The resolution factor in HPLC is used to quantify the degree of separation between two adjacent peaks on a chromatogram. It is calculated by dividing the difference in retention times of the two peaks by the sum of their peak widths. A higher resolution factor indicates better separation between the peaks.
How do you calculate capacity factor?
Capacity utilization factor is a concept which refers to the extent to which an enterprise or a nation or an unit actually uses its installed productive capacity. Thus, it refers to the relationship between actual output that 'is' produced with the installed equipment and the potential output which 'could' be produced with it, if capacity was fully used.
How will calculate rrf in hplc?
To calculate relative retention factor (RRF) in HPLC, you need to divide the retention time of the compound of interest by the retention time of the reference compound. The formula is RRF = (Retention time of compound of interest) / (Retention time of reference compound). This value helps in comparison and identification of compounds in the chromatogram.

In what ways does the theoritical plate help us in HPLC?
It can tell you about its capacity to separate substances in chromatography. The same is used in distillative separation.
How do you calculate derating factor for cables?
The derating factor for cables is calculated by considering various environmental factors such as ambient temperature, grouping of cables, and installation conditions. First, determine the cable's current-carrying capacity based on its specifications. Then, apply correction factors from relevant standards or tables for each influencing factor, multiplying these factors together to obtain the overall derating factor. Finally, multiply the original capacity by the derating factor to find the adjusted capacity for safe operation.
