what is rf value? give details
Answers
Answer:
RF in Chromatography:
RF value is the degree of retention of a component retardation factor. RF value does not have units since the both lower and upper cases are in distance, and hence the unit gets cancelled. Here the distance is measured up to the center of the spot. RF value = (Distance traveled by the component) / (Distance traveled by the mobile phase)
RF in Radio Frequency:
Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around 20 kHz to around 300 GHz. This is roughly between the upper limit of audio frequencies and the lower limit of infrared frequencies; these are the frequencies at which energy from an oscillating current can radiate off a conductor into space as radio waves. Different sources specify different upper and lower bounds for the frequency range.
