Chromatographic peak resolution is given by = + where t R is the retention time and w b is the peak width at baseline. The bigger the time-difference and/or the smaller the bandwidths, the better the resolution of the compounds. Here compound 1 elutes before compound 2.
3) Changing α is the most effective way of increasing resolution. This can be done by choosing a stationary phase that has a greater difference between k 1 ' and k 2 '. It can also be done in L.C. by using pH to invoke secondary equilibria (if applicable). The fundamental resolution equation is derived as follows:
From the variables in the figure above, the resolution, plate number, and plate height of the column plate model can be calculated using the equations: Resolution (R s): R s = 2(t RB – t RA)/(w B + w A), where: t RB = retention time of solute B t RA = retention time of solute A w B = Gaussian curve width of solute B w A = Gaussian curve width ...

A high value for resolution corresponding to good separation of peaks is similar to the convention used with chromatography separations, [13] although it is important to note that the definitions are not the same. [14] High resolution indicating better peak separation is also used in ion mobility spectrometry. [15]
Geological engineer Paul Santi said the chances of Pollard surviving if she slipped into the sinkhole were “pretty small.” “There’s a lot of problems,” said Santi, a professor at the ...
What a happy bunch of doggies! Nina even introduced some of the gang to her audience. Like Penny, a happy Golden girl who had a huge smile on her face. Or two German Shepherds, who were having a ...
The EDID PROM can often be read by the host PC even if the display itself is turned off. Many software packages can read and display the EDID information, such as read-edid [2] for Linux and DOS, PowerStrip [3] for Microsoft Windows and the X.Org Server for Linux and BSD unix.
