massXpert is able to work with every linear polymer. For the program to be able to cope with a variety of possibly very di erent polymers, it had to be written using some abstraction layer in between the mass calculations engine and the mere description of the polymer sequence.

The massXpert mass spectrometry software suite has been designed to be able to work with every linear polymer. Well, in a certain way this is true.

For the program to be able to cope with a variety of possibly very dierent polymers, it had to be written using some abstraction layer in between the mass calculations engine and the mere description of the polymer sequence.

All the data dealt with in massXpert are stored on disk as XML-formatted les.

massXpert Features:
1. highly configurable sequence editor using user-defined monomer vignettes
2. definition of atoms with any number of isotopic mass/abundance pairs
3. definition of brand new polymer chemistries
4. polymer sequence cleavage using user-defined flexible cleavage agents
5. gas-phase fragmentation of oligomers using user-defined flexible fragmentation rules
6. powerful mass search in a polymer sequence with associated ion charge values ranges
7. powerful Copy/Paste paradigm allowing the pasted polymer sequence to be purified
8. calculation of isotopic pattern of any chemical starting from a formula
