Gated Trapped Ion Mobility Spectrometry Coupled to Fourier Transform Ion Cyclotron Resonance Mass Spectrometry.

International journal for ion mobility spectrometry : official publication of the International Society for Ion Mobility Spectrometry

Ridgeway ME, Wolff JJ, Silveira JA, Lin C, Costello CE, Park MA.
PMID: 27667964
Int J Ion Mobil Spectrom. 2016 Sep;19(2):77-85. doi: 10.1007/s12127-016-0197-0. Epub 2016 Mar 29.

Analysis of molecules by ion mobility spectrometry coupled with mass spectrometry (IMS-MS) provides chemical information on the three dimensional structure and mass of the molecules. The coupling of ion mobility to trapping mass spectrometers has historically been challenging due...

Hypertension presenting early in pregnancy.

Clinical case reports

Melvin A, Kinsley B.
PMID: 26734147
Clin Case Rep. 2015 Nov 05;3(12):1056-7. doi: 10.1002/ccr3.392. eCollection 2015 Dec.

Paraganglioma in pregnancy is an exceedingly rare and potentially life-threatening diagnosis. It is important that the clinicians consider secondary causes when women present with hypertension in early pregnancy.

Gas-phase separation using a trapped ion mobility spectrometer.

International journal for ion mobility spectrometry : official publication of the International Society for Ion Mobility Spectrometry

Fernandez-Lima F, Kaplan DA, Suetering J, Park MA.
PMID: 24163587
Int J Ion Mobil Spectrom. 2011 Sep;14(2). doi: 10.1007/s12127-011-0067-8.

In the present work we describe the principles of operation, versatility and applicability of a trapped ion mobility spectrometer (TIMS) analyzer for fast, gas-phase separation of molecular ions based on their size-to-charge ratio. Mobility-based separation using a TIMS device...

Validation of Calibration Parameters for Trapped Ion Mobility Spectrometry.

Journal of the American Society for Mass Spectrometry

Naylor CN, Reinecke T, Ridgeway ME, Park MA, Clowers BH.
PMID: 31392697
J Am Soc Mass Spectrom. 2019 Oct;30(10):2152-2162. doi: 10.1007/s13361-019-02289-1. Epub 2019 Aug 07.

Using contemporary theory for ion mobility spectrometry (IMS), gas-phase ion mobilities within a trapped ion mobility-mass spectrometer (TIMS) are not easily deduced using first principle equations due to non-linear pressure changes and consequently variations in E/N. It is for...

Ru-Doped Wells-Dawson Polyoxometalate as Efficient Catalyst for Glycerol Hydrogenolysis to Propanediols.

Materials (Basel, Switzerland)

Modvig A, Kumpidet C, Riisager A, Albert J.
PMID: 31284581
Materials (Basel). 2019 Jul 06;12(13). doi: 10.3390/ma12132175.

A Ru-doped phospho-tungstic Wells-Dawson polyoxometalate (POM) was successfully applied as homogeneous catalyst for glycerol hydrogenolysis in aqueous media. The synthesized compound showed superior catalytic activity compared to classical homogeneous/heterogeneous Ru catalysts like RuCl

Tandem trapped ion mobility spectrometry.

The Analyst

Liu FC, Ridgeway ME, Park MA, Bleiholder C.
PMID: 29594263
Analyst. 2018 May 15;143(10):2249-2258. doi: 10.1039/c7an02054f.

There is currently a strong interest in the use of ion mobility spectrometry-mass spectrometry (IMS-MS) instrumentation for structural biology. In these applications, momentum transfer cross sections derived from IMS-MS measurements are used to reconstruct the three-dimensional analyte structure. Recent...

Increasing Analytical Separation and Duty Cycle with Nonlinear Analytical Mobility Scan Functions in TIMS-FT-ICR MS.

Analytical chemistry

Benigni P, Porter J, Ridgeway ME, Park MA, Fernandez-Lima F.
PMID: 29376337
Anal Chem. 2018 Feb 20;90(4):2446-2450. doi: 10.1021/acs.analchem.7b04053. Epub 2018 Feb 08.

In this work, nonlinear, stepping analytical mobility scan functions are implemented to increase the analytical separation and duty cycle during tandem Trapped Ion Mobility Spectrometry and FT-ICR MS operation. The differences between linear and stepping scan functions are described...

Antimicrobial Activity of Chitosan-Based Films Enriched with Green Tea Extracts on Murine Norovirus, .

International journal of food science

Amankwaah C, Li J, Lee J, Pascall MA.
PMID: 32714970
Int J Food Sci. 2020 Jul 02;2020:3941924. doi: 10.1155/2020/3941924. eCollection 2020.

Edible films can be designed to serve as carriers of antimicrobial agents and be used to control pathogenic foodborne viruses and bacteria. This research tested this concept by dissolving green tea extract (GTE) in chitosan film-forming solutions (FFS) and...

Heat-induced compounds development in processed tomato and their influence on corrosion initiation in metal food cans.

Food science & nutrition

Dhuey E, Castada HZ, Barringer S, Joseph J, Hadad CM, Ruffley K, Pascall MA.
