Journal ArticleDOI
Automated data massaging, interpretation, and e-mailing modules for high throughput open access mass spectrometry
TL;DR: Hardware components and software modules were configured to enhance the automation, efficiency, and reliability of a commercial open access atmospheric pressure ionization mass spectrometry (API/MS) system for flow injection analysis.
Journal ArticleDOI
Rapid methods for screening low molecular mass compounds non-covalently bound to proteins using size exclusion and mass spectrometry applied to inhibitors of human cytomegalovirus protease.
TL;DR: General and rapid methods were developed for determining the extent of non-covalent binding between small molecules and proteins, using the model system of human cytomegalovirus protease and several drug candidates which inhibit the protease by non- covalently binding to it.
Journal ArticleDOI
Comparative mass spectrometric analyses of Photofrin oligomers by fast atom bombardment mass spectrometry, UV and IR matrix-assisted laser desorption/ionization mass spectrometry, electrospray ionization mass spectrometry and laser desorption/jet-cooling photoionization mass spectrometry.

TL;DR: This study provides a side-by-side comparison of the spectra for the five different mass spectrometric techniques used in the analysis of Photofrin.
Journal ArticleDOI
Evaluation of a dual electrospray ionization/atmospheric pressure chemical ionization source at low flow rates (∼50 µL/min) for the analysis of both highly and weakly polar compounds
TL;DR: In this paper, the atmospheric pressure ionization (API) source for a commercial mass spectrometer was modified to operate as a dual source in both the electrospray ionization and atmospheric pressure chemical ionization by simultaneously utilizing the probe and the corona discharge needle.
Journal ArticleDOI
Biopolymer sequencing using a triple quadrupole mass spectrometer in the ESI nozzle-skimmer/precursor ion MS/MS mode.
TL;DR: A variety of model biopolymers, including oligonucleotides, oligosaccharides and a synthetic pharmaceutical agent, were sequenced using a triple quadrupole mass spectrometer equipped with an electrospray source and operated in a scan mode referred to as pseudo-MS3.
