Have you ever wondered why there was no systematic approach for identifying unknown compounds from a mass spectrum? Mass spectra, unlike NMR and IR spectra, have no frame of reference. Each fragment mass has to be interpreted in the context of other masses.
Are you open to new approaches? If accurate mass fragmentation data is available in your laboratory, our patented pattern recognition software allows you to visualize your unknown molecule as being composed of underlying small "subfragments" that show how fragment ions are related to each other. (See the Leucine-Enkephalin example below.) This pattern recognition software, now available as a simple and economical Excel® Add-In, uses the power of mathematics to rapidly transform accurate-mass fragmentation data into a structure-orientated graphical format, and our high resolution isotope calculator worksheet plots the isotope distributions in color based on the selected resolution setting. (Isotope Worksheet).
