In ESI-MS Spektren werden zum Teil sehr intensive Adduktionen beobachtet, die mehrere intakte protonierte bzw. deprotonierte Analytmoleküle enthalten (z.B. [M 2] 7-oder [M 3] 5-bei ESI-MS von Cytochrom.

ESI-Spektren sind charakterisiert durch das Auftreten von Quasi-Molekülionen wie [M + H] +, [M + Na] +. Größere Probenmolekel (mit größerer Oberfläche) werden bevorzugt mehrfach ionisiert zu [M + 2H] 2+ , [M + 3H] 3+ , [M + 4H] 4+ , etc. Die Signale im Massenspektrum liegen aufgrund der Mehrfachladung dann bei Massenzahlen entsprechend der Hälfte von [M + 2], einem Drittel von [M + 3], einem Viertel von [M + 4], usw Ein weiteres charakteristisches Phänomen ist die Bildung mehrfach geladener Ionen. ESI wird meist mit Ionenfallen-, Quadrupol- oder TOF-Analysatoren gekoppelt. Anwendung. Elektrosprayionisation ist eine Technik zur Erzeugung von Ionen, die in der Massenspektrometrie verwendet wird.

Electrospray ionization is a technique used in mass spectrometry to produce ions using an electrospray in which a high voltage is applied to a liquid to create an aerosol. It is especially useful in producing ions from macromolecules because it overcomes the propensity of these molecules to fragment when ionized. ESI is different from other ionization processes since it may produce multiple-charged ions, effectively extending the mass range of the analyser to accommodate the kDa. Ein Ion der Masse M wird demzufolge im Spektrum bei der Massenzahl m = [M + n ⋅ H] / n beobachtet. Wird diese Betrachtung für zwei benachbarte Ionen im Spektrum, deren Ladung und Protonenzahl sich ja um 1 unterscheiden, durchgeführt, erhält man folgende zwei Gleichungen: m 1 = [M + n ⋅ m H] / n m 2 = [M + (n + 1) ⋅ m H] / (n + 1) Da m H = 1 ist, ergibt sich Mas­sen­spek­trum von Ace­tyl­sa­li­cyl­säu­re (EI) Das Signal bei der höchsten Masse stellt (von wenigen Ausnahmen abgesehen) den Molekülionenpeak dar. Aus diesem Peak kann direkt das Molekulargewicht der Probe entnommen werden Interpreting ESI Spectra The Y axis is labeled relative intensity. The X axis is mass divided by charge, m/z.

Massenspektrometrie bezeichnet ein Verfahren zum Messen der Masse von Atomen oder Molekülen. Die zu untersuchenden Moleküle werden dabei in die Gasphase überführt und ionisiert. Die Ionen werden anschließend durch ein elektrisches Feld beschleunigt und dem Analysator zugeführt, der sie nach ihrem Masse-zu-Ladung-Verhältnis m/z sortiert, beispielsweise räumlich in Teilstrahlen auftrennt wie in einem Sektorfeld-Massenspektrometer. Die Moleküle können dabei fragmentiert werden. Electrospray Ionization Mass Spectrometry is a technique used to determine molecular weights for proteins, peptides, and other biological macromolecules such as oligosaccharides 1. Originally described by Canadian-American Physicist Sir Arthur J. Dempster in an article titled A new method of positive ray analysis Der Begriff der Elektrospray -Ionisation (ESI) geht auf Arbeiten von Dole (1968) zurück und wurde durch John B.

The experimental spectrum agrees with the predicted spectrum with respect to the m/z values of the major peaks, which differ only slightly from the predicted values. The spectra differ in two ways: first, the intensity of the peaks varies because some charge states are more favorable than others; second, the experimental spectrum has additional smaller peaks at higher m/z values arising from low.

The ESI-MS/MS spectrum of quercetin-3-O-glucoside also showed a fragment ion at m/z 300, which is characteristic of the deprotonated radical aglycone ion [quercetin-H] −, formed by the homolytic cleavage of the O-glycosidic bond, and has been proposed as indicative of quercetin glycosides [46,50] 1 Supporting Information Structure Elucidation of the Spiro-polyketide Svalbardine B from the Arctic Fungal Endophyte Poaceicola sp.
