Fragmentation patterns of Chromophore‐Tagged Peptides in Visible Laser Induced Dissociation.

08-Sep-2017 | Lény Garcia, Jérôme Lemoine, Philippe Dugourd, Marion Girod, Rapid Communications in Mass Spectrometry, 2017

Abstract RATIONALE Tandem mass spectrometry (MS/MS) is the pivotal tool for protein structural characterization and quantification. Identification relies on the fragmentation step of tryptic peptides in bottom‐up strategy. Specificity of fragmentation can be obtained using laser induced ...

An Investigation of the Beam Damage Effect on In Situ Liquid SIMS Analysis

08-Sep-2017 | Xiaofei Yu, Jiachao Yu, Yufan Zhou, Yanyan Zhang, Jungang Wang, James E. Evans, Xiao‐Ying Yu, Xue‐Lin Wang, Zihua Zhu, Rapid Communications in Mass Spectrometry, 2017

Abstract RATIONALE During in situ liquid SIMS analysis, the primary ion beam was normally scanned on a very small area to collect signals with high ion doses (1014‐1016 ions/cm2). As a result, beam damage may become a concern when compared with static limit of SIMS analysis, in which the ...

Identification and characterization of vilazodone metabolites in rats and microsomes by UHPLC/Q‐TOF/MS/MS

06-Sep-2017 | Balasaheb B. Chavan, Pradipbhai D. Kalariya, Shristy Tiwari, Rakesh D. Nimbalkar, Prabha Garg, R. Srinivas, M.V.N. K ..., Rapid Communications in Mass Spectrometry, 2017

Abstract Rationale Vilazodone is a selective serotonin reuptake inhibitor (SSRI) used for the treatment of major depressive disorder (MDD). Extensive literature search indicated scarce reports on in vivo and in vitro metabolism of vilazodone. Therefore, we report a comprehensive in vivo and ...

Comparison of linear intrascan and interscan dynamic ranges of Orbitrap and ion‐mobility time‐of‐flight mass spectrometers

06-Sep-2017 | Anton Kaufmann, Stephan Walker, Rapid Communications in Mass Spectrometry, 2017

Abstract Rationale The linear intrascan and interscan dynamic ranges of mass spectrometers are important in metabolome and residue analysis. A large linear dynamic range is mandatory if both low and high abundance ions have to be detected and quantitated in heavy matrix samples. These ...

The inherent matrix properties of lichen metabolites in MALDI‐TOF MS

05-Sep-2017 | Pierre Le Pogam, Joël Boustie, Pascal Richomme, Antoine Denis, Andreas Schinkovitz, Rapid Communications in Mass Spectrometry, 2017

Abstract RATIONALE Light‐absorbing secondary metabolites from lichens were recently reported to exhibit promising Laser Desorption Ionization (LDI) properties, enabling their direct detection from crude lichen extracts. In addition, many of them display close structural homologies to ...

LC/MS based detection and semi‐quantitative analysis of INSL5 in human and murine tissues

31-Aug-2017 | R.G. Kay, S. Galvin, P. Larraufie, F. Reimann, F.M. Gribble, Rapid Communications in Mass Spectrometry, 2017

Abstract Rationale Insulin Like Peptide 5 (INSL5) is a hormone produced by enteroendocrine L‐cells in the colon that has recently been implicated in the control of metabolic homeostasis. However, research into its physiology has been hindered by the reported unreliability of commercially ...

Ion Suppression Effect in DESI Mass Spectrometry and ESI Mass Spectrometry

31-Aug-2017 | Zheng Wang, Haijing Zhu, Guangming Huang, Rapid Communications in Mass Spectrometry, 2017

RATIONALE Although desorption electrospray ionization (DESI) is claimed to have less ion suppression effect than electrospray ionization (ESI), related investigation with quantification measurement of ion suppression effect is absent. Herein, comparative analysis of ion suppression effect ...

Stable isotope discrimination factors and between‐tissue isotope comparisons for bone and skin from captive and wild green sea turtles (Chelonia mydas)

31-Aug-2017 | Calandra N. Turner Tomaszewicz, Jeffrey A. Seminoff, Mike Price, Carolyn M. Kurle, Rapid Communications in Mass Spectrometry, 2017

Abstract RATIONALE The ecological application of stable isotope analysis (SIA) relies on taxa‐ and tissue‐specific stable carbon (Δ13C) and nitrogen (Δ15N) isotope discrimination factors, determined with captive animals reared on known diets for sufficient time to reflect dietary isotope ...

Direct Analysis of Volatile Organic Compounds in Foods by Headspace Extraction Atmospheric Pressure Chemical Ionisation Mass Spectrometry

30-Aug-2017 | P. Perez‐Hurtado, E. Palmer, T. Owen, C. Aldcroft, M.H. Allen, J. Jones, C.S. Creaser, M.R. Lindley, M.A. Turner, J. ..., Rapid Communications in Mass Spectrometry, 2017

Abstract RATIONALE The rapid screening of volatile organic compounds (VOCs) by direct analysis has potential applications in the areas of food and flavour science. Currently the technique of choice for VOC analysis is gas chromatography‐mass spectrometry (GC/MS). However, the long ...

An optical method for carbon dioxide isotopes and mole fractions in small gas samples: Tracing microbial respiration from soil, litter, and lignin

29-Aug-2017 | Steven J. Hall, Wenjuan Huang, Kenneth E. Hammel, Rapid Communications in Mass Spectrometry, 2017

ABSTRACT RATIONALE Carbon dioxide isotope (δ13C value) measurements enable quantification of the sources of soil microbial respiration, thus informing ecosystem C dynamics. Tunable diode lasers (TDLs) can precisely measure CO2 isotopes at low cost and high throughput, but are seldom used for ...
