Electrochemical Push–Pull Scanner with Mass Spectrometry Detection

Enzyme activity evaluation by differential electrochemical mass spectrometry.

NAD-dependent alcohol dehydrogenase (ADH) enzymes for ethanol oxidation were investigated by differential electrochemical mass spectrometry (DEMS). The broad mass spectra obtained under bioelectrochemical control and with unprecedented accuracy were used to provide new insight into the enzyme kinetics and mechanisms.

Thiol-functionalized anthraquinones: mass spectrometry and electrochemical studies

ABSTRACT In this work, the synthesis of various thiol-functionalized anthraquinone compounds is presented. The studied compounds were characterized by mass spectrometry and the main fragmentation pathways are discussed. The compounds studied formed stable self-assembled monolayers (SAMs) in the gold surface. The parameters for the reduction processes in the gold surface of the studied new anthr...

DETECTION OF CROSS-LINmD PERIDES BY FAST ATOM B01WBARDMENT MASS SPECTROMETRY

The possibility of chemical modification of peptides and proteins under the condition of proteolytic digestions and FABMS analysis was investigated. The results ;indicate that among the amino acid constituents of peptides and proteins: serinefcysteine, and cystine are the most sensitive residues which undergo chemical modificadons under the exprimenta1 conditions. The chemical modification ...

Capillary Electrophoresis/Tandem Mass Spectrometry with Array Detection

Charge Detection Mass Spectrometry with Almost Perfect Charge Accuracy.

Charge detection mass spectrometry (CDMS) is a single-particle technique where the masses of individual ions are determined from simultaneous measurement of each ion's mass-to-charge ratio (m/z) and charge. CDMS has many desirable features: it has no upper mass limit, no mass discrimination, and it can analyze complex mixtures. However, the charge is measured directly, and the poor accuracy of ...
