User-defiend Formulas

There is a set of peak parameters that are typically included into reports, such as Height, Area, Width at Half-Height, Asymmetry, Concentration and some other. The core of Chrom&Spec software supports user-selectable formulas for some of parameters – e.g. Efficiency, Asymmetry, Resolution, Retention Index. Besides, in the cases of scientific calculations or method/device validation there is a need for more sophisticated calculations.

To support maximal flexibility with any method, Chrom&Spec allows the user to program into the report any conceivable calculation of peak parameters. These user-defined formulas are a powerful tool for solving non-standard tasks.

Formulas are written in a specially designed macro language, consisting of mathematical operators and macro-definitions. The language allows addressing of any peak in the chromatogram, calculates sums and averages, supports a lot of special functions, such as calculation of peak width at a given height, center of mass or median retention times, peak moments, spectral ratios, etc. Calculated values can be included into the peak table along with predefined ones.
