  2. Resolution (chromatography) - Wikipedia

    en.wikipedia.org/wiki/Resolution_(chromatography)

    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. Fundamental resolution equation - Wikipedia

    en.wikipedia.org/wiki/Fundamental_Resolution...

    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:

  4. Purnell equation - Wikipedia

    en.wikipedia.org/wiki/Purnell_equation

    The Purnell equation is an equation used in analytical chemistry to calculate the resolution R s between two peaks in a chromatogram. [1] [2]= (′ + ′) where R s is the resolution between the two peaks

  5. Display resolution standards - Wikipedia

    en.wikipedia.org/wiki/Display_resolution_standards

    The most common aspect ratios for graphics displays are 4:3, 16:10 (equal to 8:5), 16:9, and "21:9". The aspect ratio also affects the perceived size of objects on the screen. [5] The native screen resolution together with the physical dimensions of the graphics display can be used to calculate its pixel density. An increase in the pixel ...

  6. Resolution (mass spectrometry) - Wikipedia

    en.wikipedia.org/wiki/Resolution_(mass_spectrometry)

    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]

  7. List of common display resolutions - Wikipedia

    en.wikipedia.org/wiki/List_of_common_display...

    This chart shows the most common display resolutions, with the color of each resolution type indicating the display ratio (e.g., red indicates a 4:3 ratio). This article lists computer monitor, television, digital film, and other graphics display resolutions that are in common use. Most of them use certain preferred numbers.

  8. OpenChrom - Wikipedia

    en.wikipedia.org/wiki/OpenChrom

    OpenChrom is an open source software for the analysis and visualization of mass spectrometric and chromatographic data. [4] Its focus is to handle native data files from several mass spectrometry systems (e.g. GC/MS, LC/MS, Py-GC/MS, HPLC-MS), vendors like Agilent Technologies, Varian, Shimadzu, Thermo Fisher, PerkinElmer and others.
