المصدر: Mass Spec Calculator Professional 4.09 في منتدى : قسم البرامج العلمية Mass Spec Calculator Professional 4.09 Mass Spec Calculator Professional 4.09 | 1.6 Mb This program includes several functions that assist in the evaluation of mass spectra. Molecular drawing, fragmentation, and autofragmentation Enhanced Isotopic Profile utility based on a completely new algorithm that calculates isotopic mass distributions for a structure. Elemental Formula utility calculates the possible compositions of an ion given its mass. Spectrum Capture utility that can automatically digitize a scanned spectrum and import it for use within MSC. All modules now support 79 elements, including essentially any element likely to be encountered in mass spectrometry. All elemental data including mass, number of isotopes, and each isotope's mass and relative abundance can be easily edited if desired. Automatically adjusts to the available screen resolution to maximize the drawing space; additional virtual screen space can be accessed by activating scrollbars. The drawing routines have been improved, several new options have been added, a tool bar and pop-up menu are included for additional ease of use, and a new alkyl chain tool and a user-defined "R-group" tool have been added to further speed the drawing process. Improved spectrum and printing capabilities. Home Page: =========
