Autor: Roman Zazula, Miroslav Průcha, František Pehal, Kseniya Dryahina, Michal Moravec, Martin Müller, Tomáš Nejtek

Publikováno v: Prague Medical Report, Vol 120, Iss 2, Pp 103-106 (2019)

Myristic acid was identified as a metabolite with the highest diagnostic sensitivity and specificity in the metabolome of patients with bacteraemia. Subsequently, its significant decrease was observed in patients in septic shock not responding to tre

Publikováno v: Analytical Chemistry. 94:13163-13170

Hydride atomization and the fate of free analyte atoms in an externally heated quartz tube atomizer (QTA) were investigated employing selected ion flow tube mass spectrometry (SIFT-MS). SIFT-MS proved to be ideally suited to study water concentration

Ligand Switching Ion Chemistry: An SIFDT Case Study of the Primary and Secondary Reactions of Protonated Acetic Acid Hydrates with Acetone

Autor: Patrik Španěl, Michal Lacko, David Smith, Kseniya Dryahina, Anatolii Spesyvyi

Publikováno v: Journal of the American Society for Mass Spectrometry. 32:2251-2260

A study was performed of the reactions of protonated acetic acid hydrates, CH3COOHH+(H2O)n, with acetone molecules, CH3COCH3, using a selected ion flow-drift tube (SIFDT). The rationale for this study is that hydrated protonated organic molecules are

Sensitivity of secondary electrospray ionization mass spectrometry to a range of volatile organic compounds: Ligand switching ion chemistry and the influence of Zspray™ guiding electric fields

Autor: Patrik Španěl, Miroslav Polášek, David Smith, Kseniya Dryahina

Publikováno v: Rapid Communications in Mass Spectrometry. 35

RATIONALE Secondary electrospray ionization (SESI) is currently only semi-quantitative. In the Zspray™ arrangement of SESI-MS, the transfer of ions from near atmospheric pressure to a triple quadrupole is achieved by guiding electric fields that pa
