The Rf value is the "ratio to the front." Hence the R and the f. It is defined as the ration of the distance traveled by a spot (measured from the center) to the distance traveled by the solvent.

∙ 11y agoIf you are referring to the Rheumatoid factor, this will distinguish rheumatoid arthritis from other types of arthritis as the symptoms are similar and treatment can be targeted to rheumatoid arthritis.

How is rf factor in chromatography calculated?
It's not.
What does Rf Values in chromatography represent?
It is the rate of flow for each color. It is calculated by taking the value for the measured from the initial color mark to the solvent front (value A) and then the distance from the initial spot to each of the centers of the color marks separated (value B). You then divide B by A. For example, solvent front for black felt tip pen is 5.4cm and the distance for value B is .9 cm. The rf for this problem is .9cm/5.4 cm = .17 (Rf factor is a unitless number)
What is the RF value for aspirin using TLC?
Rf value changes with every experiences..... it depends on what was your solvant, the room température, the chromatograph you used..... that's why you wont find Rf tables in organic chemistry books
If the Rf factor of a pigment is .8400 and the distance that the solvent traveled is 12 cm how far did the pigment travel?
10.08
What is a rf scale?
An RF scale is a Representative Fraction (RF) Scale
How is rf factor in chromatography calculated?
It's not.
What does Rf stand for How can it be calculated?
retadartion factor calculate it by Rf= distence moved by chemical distence moved by solvent ; ;-)
What is the full name of rf?
Retention Factor Rf == Distance traveled / total distance
Does Rf means resolution factor in paper chromatography?
Rf is nothing but retardation factor in paper chromatography.Rf= distance spot traveled/distance solvent traveled

What is a negative rheumatoid factor?
rheumatoid factor is a particular type of antibody that is found in about 80% of people have Rheumatoid arthritis as well as with other inflammatory illnesses. A negative RF simply means there is no RF in the blood.
What CPt code is used for rheumatoid factor?
CPT Code(s):86200 CCP IgG; 86431 Rheumatoid Factor; if reflexed, add 83516 x2 RF IgG/IgA and 86431 RF IgM

Is a Rf value of 0.95 strongly held on the paper or in the solution?
The retention factor, or Rf, refers to the ratio of time an analyte is retained in the stationary phase to the time it is retained in the mobile phase. An Rf value of 0.95 is strongly held on paper than in the solution.
If your Rheumatoid factor is lower than the previous blood test what does this mean?
This is not known as the cause of it is unknown as well as the relationship between RF and the activity of the disease.
Can you have rheumatoid arthritis with a factor 7.7?
Yes You can have Rheumatoid arthritis with no RF at all. In that case it is referred to as seronegative RA,
