What do you mean rf cable?
RF = Radio Frequency
What is the advantage of RF over IR?
Because RF does not require line-of-sight.
Why rf choke is used in collpitts oscillator?
To isolate the bias circuitry of the transistor from the feedback network with RF currents.
How plasma is produced using RF generator?
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.
What are the Difference Between AF Amplifier and RF Amplifier?
The amp for audio freq. is a AF amplifier. The RF amp is for radio freqs.
What is the rf value of cocaine?
Rf is about .45
What is the Rf value of salicylamide?
It will depend on the solvent system you are using.
What is rf value and how is determine?
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
What is an rf value used for?
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.
What is substance that have 0.803 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.
What is the maximum and RF value can be?
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.
How does saturation effect RF value?
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.
What is the RF value for red ink blue ink and green ink?
the Rf value value is 8.44 as the particles are lighter than the solvent
What do the Rf values indicate about the relative solubility of the pigment in the 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.
What is the relationship between chain length and Rf value?
As a general rule the longer the carbon chain the greater the Rf value.
What is rf value of eugenol?
The Rf value of eugenol is around 0.61-0.63, when using a suitable solvent system like ethyl acetate:benzene (7:3).
What does it mean if the Rf value is 1?
An Rf value of 1 means that the compound traveled the same distance as the solvent in a chromatography experiment, indicating that the compound is very soluble in the solvent and did not adhere to the stationary phase.
