Peak shape models Subject

Chapter 4 starts with some basic equations, which relate the molecular-kinetic picture of gas-solid chromatography and the experimental data. Next come some common mathematical properties of the chromatographic peak profiles. The existing attempts to find analytical formulae for the shapes of TC peaks are subject to analysis. A mathematical model of migration of molecules down the column and its Monte Carlo realization are discussed. The zone position and profile in vacuum thermochromatography are treated as chromatographic, diffusional and simulation problems. 

Soft matter structure is characterized by a continuous density function, p (r), which is subjected to Fourier transform by the scattering experiment yielding a continuous intensity function, / (s), which does not drop to zero in long intervals between narrow peaks. Thus, for any m-depth analysis of distorted structure, either we have to model the complete shape of the pattern, or we have to switch to real space, again supplying the respective transform with a complete intensity function.
