WebEquation (1) indicates that the resolution is the difference between peak retention times divided by the average peak width. In a peak with Gaussian distribution, the peak width is W = 4 σ (where σ is the standard deviation) and the peak FWHM is W0.5h = 2.354σ. Substituting these relationships into equation (1) gives results in equation (2). WebMethanol and acetonitrile are organic acids commonly used as the mobile phase in reverse-phase chromatography. The properties of these two organic acids differ, and below we outline 7 key differences to keep in mind when using methanol or acetonitrile for analysis. 1, Column Pressure. 2, Absorption Spectrum. th-9800 mars mod
