RF value (in chromatography) The distance travelled by a given component divided by the distance travelled by the solvent front
numeric perception is a value of perception to the numeric value
David Easton define politics as authoritative allocation of value.
Added value is the difference between the selling price of a good or service and the cost of brought in materials or the value of inputs
slope of best fit gives mean value?
radio frequency
Rf is about .45
It will depend on the solvent system you are using.
the mobility of any component in a particular solvent is referred to as its RF value. Mathematically, RF value = distance travelled by solute/ distance travelled by the solvent
The rf value is shorthand for the retention value of a substance. It is used in chromatography to determine the components of an unknown sample.
The maximum RF value that can be obtained is 1.0. This means that the substance travels the full distance of the chromatography medium being used. Any RF value greater than 1 is not physically possible.
In general, as saturation increases, the RF value decreases. This is because an increase in saturation tends to increase retention of the compound on the stationary phase, resulting in a lower RF value. Conversely, lower saturation levels may allow the compound to move more freely, leading to a higher RF value.
The RF value of benzoic acid in ethyl acetate is 0.68.
the Rf value value is 8.44 as the particles are lighter than the solvent
The Rf values do not indicate the solubility of a substance. The Rf value or retardation factor is the ratio of the distance traveled by the center of a pot to the distance traveled by the solvent front in chromatography.
As a general rule the longer the carbon chain the greater the Rf value.
