RF = Radio Frequency
Because RF does not require line-of-sight.
To isolate the bias circuitry of the transistor from the feedback network with RF currents.
It's power that is loss during the tuning of the RF network. Ideally the reflective power is tuned to zero before striking the plasma to maximize the efficiency of the RF generator.
The amp for audio freq. is a AF amplifier. The RF amp is for radio freqs.
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
An RF value of 250 typically refers to the retention factor in chromatography. It represents how strongly a compound is adsorbed to the stationary phase relative to the mobile phase. A higher RF value indicates more interaction with the stationary phase and less with the mobile phase.
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 a substance is a measure of its migration distance during chromatography. A substance with an Rf value of 0.803 would mean that it traveled 80.3% of the total distance from the origin to the solvent front during the chromatography process. The specific identity of the substance would depend on the experimental conditions and the properties of the compound.
the Rf value value is 8.44 as the particles are lighter than the solvent
The Rf value indicates the ratio of the distance a pigment travels compared to the distance the solvent travels on a chromatography plate. The higher the Rf value, the more soluble the pigment is in the solvent used for the chromatography.
As a general rule the longer the carbon chain the greater the Rf value.
