How to calculate yield from hplc
WebTherefore, F is constant. What this means is that regardless of the amounts of octane and nonane in solution, the ratio of the ratios of area to concentration will always yield a constant. In practice, a solution containing known amounts of both octane and nonane is injected into a GC and a response factor, F, is calculated.

Web1. Calculation of total column volume (also used for calculating bed volume): Where: V = calculated column volume r = column radius L = length of the column (or packed bed) 2. Calculation of empty column linear flow rate from volumetric flow rate: Where: u = Linear flow rate (cm/hr) F = volumetric flow rate (mL/hr) [multiply mL/min x 60 min/hr] WebSelectivity is the ability of an HPLC method to separate two analytes from each other. Selectivity usually is abbreviated with the Greek letter α, and is calculated as: α = k 2 / k 1 where k 1 and k 2 are the retention factors, k, of the first and second peaks of a peak pair.
