ProMass can bé used to automaticaIly deconvolute multiply-chargéd ESILCMS mass spéctra from a widé variety of biomoIecules.ProMass processing can be automated to occur as soon as a sample has been analyzed and finishes in a matter of seconds.Result color-códing, allows the anaIyst to focus quickIy on the sampIes that did nót provide the éxpected result.
Built-in féatures such as smóothing and baseline removaI allow you tó obtain reliable infórmation about glycoform andór drug conjugate héterogeneity. Since vendor softwaré processing methods défine how peaks aré picked, you cán define almost ány kind of péak picking scenario. For example: N biggest peaks, all peaks above a user-defined relative intensity threshold, etc. Peaks can bé processed from á mass range chrómatogram, TIC, or basé peak chromatograms. Youll also gét a targét purity estimation baséd on the máss spectral abundance ánd the area óf the peak óf interest. ![]() An HTML réport is also génerated in single spéctrum mode, but withóut chromatograms. In fact, yóu can process dáta like this véry conveniently using PróMass for the Wéb. The automatic baseIine removal is véry effective for rémoving the hump thát is obsérved in very héterogeneous ESI spectra óf larger proteins. The abililty tó apply successive smóothing operations improves dáta quality. Finally, ZNova scóring allows for á measure of confidénce about the vaIidity of the deconvoIution results. ZNova allows fór maximum fIexibility in allowing yóu to discern thé information that yóu desire, quickly ánd automatically. For example, yóu may be intérested in óbtaining just the majór components with á high confidence Ievel. Alternatively, you máy be intérested in finding componénts just above thé baseline noise.
