What does RF stand for in technology?
Radio Frequency (RF) is the mode of communication for wireless technologies of all kinds, including cordless phones, radar, ham radio, GPS, and radio and television broadcasts. This technology is so much a part of our lives we scarcely notice it for its ubiquity. From baby monitors to cell phones, Bluetooth® to remote control toys, radio waves ...

What does Rf stand for science?
The amount that each component of a mixture travels can be quantified using retention factors (Rf). The retention factor of a particular material is the ratio of the distance the spot moved above the origin to the distance the solvent front moved above the origin.
What is an Rf in biology?
(2) Retardation factor (Rf) in chromatographic separation, is the ratio of the distance travelled by the substance of interest to the distance simultaneously travelled by the mobile phase: always less than 1. From: The Dictionary of Cell & Molecular Biology (Fifth Edition), 2013.
What is Rf in biochemistry?
A rheumatoid factor (RF) test measures the amount of rheumatoid factor (RF) in your blood. Rheumatoid factors are proteins produced by the immune system. Normally, the immune system attacks disease-causing substances like viruses and bacteria.
What is meant by the term Rf value in chromatography?
In thin-layer chromatography, the retention factor (Rf) is used to compare and help identify compounds. The Rf value of a compound is equal to the distance traveled by the compound divided by the distance traveled by the solvent front (both measured from the origin).
What is Rf and how does it define protein identification?
The Rf is defined as the migration distance of the protein through the gel divided by the migration distance of the dye front. The distance should be measured from the top of the resolving gel to the band of interest, as illustrated on the gel.
What do Rf values indicate?
Retardation or retention factor (Rf) value is the ratio of distance traveled by the analyte to that of the solvent front on a chromatogram. The chromatographic techniques in which the analytes are added to the stationary phases show a difference in the movement of analytes with mobile solvents (phases).
What is Rf in serology?
A rheumatoid factor test measures the amount of rheumatoid factor in your blood. Rheumatoid factors are proteins produced by your immune system that can attack healthy tissue in your body.
What does high Rf value mean?
The fastest moving spot has the highest Rf value. Therefore Rf values and polarity are inversely related. The spot with the highest Rf value is the least. polar (fastest moving), and the spot with the lowest Rf value is the most polar (slowest moving).
How is Rf value measured in chromatography?

What is Rf and Rx value?
Rf value :- It is defined as the ratio of the distance travelled by the compound at its maximum. In many cases it has been observed that the solvent front os run off the end of the chromatogram. Rx value is the ratio of the distance travelled by a substance to the distance travelled by a reference standard.
