The Russian Mass Spectrometry Interest Group (RMSIG) emerged in 1998 during the annual ASMS meeting in Orlando, FL. The original goal of the group was to help assimilating mass spectrometrists from th...
Coumarin is one of the basic structures of naturally oxygen heterocyclic compound, which was investigated in this paper for its gas-phase fragmentation behaviors using electrospray quadrupole extracti...
There is increasing interest in methods of direct analysis mass spectrometry that bypass complex sample preparation steps.
Mass spectrometry-based techniques can be applied to investigate collagen with respect to identification, quantification, supramolecular organization, and various post-translational modifications. The...
Although phenylethanoid glycosides (PhGs) occur widely in plants, their characterisation by liquid chromatography/mass spectrometry (LC/MS) is less well studied than other phenolic glycosides such as ...
We aim to evaluate the effect of an extension of conventional urine diagnostics with mass spectrometry in patients with a suspected UTI. Mass spectrometry is done directly from the urine s...
This is an experimental study of participants who had positive blood culture to compare time to appropriate antibiotic between using Microarray Assay and Mass Spectrometry to bacterial Ide...
The main objective is to establish that a new technique of amyloidosis typing by Proteomics (based on nanoLC-MS/MS mass spectrometry) allows typing in > 90% of observations in patients who...
The study is a pilot study in the feasibility of a diagnostic technique. There is no current data on detection of cisplatin in cancer cells derived from human urine. This study will genera...
The type-2 diabetes mellitus（T2DM）, metabolic syndrome, cardiovascular disease complications induced by polycystic ovary syndrome(PCOS) with insulin resistance(IR）, which become serious ...
A mass spectrometry technique using two (MS/MS) or more mass analyzers. With two in tandem, the precursor ions are mass-selected by a first mass analyzer, and focused into a collision region where they are then fragmented into product ions which are then characterized by a second mass analyzer. A variety of techniques are used to separate the compounds, ionize them, and introduce them to the first mass analyzer. For example, for in GC-MS/MS, GAS CHROMATOGRAPHY-MASS SPECTROMETRY is involved in separating relatively small compounds by GAS CHROMATOGRAPHY prior to injecting them into an ionization chamber for the mass selection.
A microanalytical technique combining mass spectrometry and gas chromatography for the qualitative as well as quantitative determinations of compounds.
An analytical method used in determining the identity of a chemical based on its mass using mass analyzers/mass spectrometers.
A mass spectrometry technique used for analysis of nonvolatile compounds such as proteins and macromolecules. The technique involves preparing electrically charged droplets from analyte molecules dissolved in solvent. The electrically charged droplets enter a vacuum chamber where the solvent is evaporated. Evaporation of solvent reduces the droplet size, thereby increasing the coulombic repulsion within the droplet. As the charged droplets get smaller, the excess charge within them causes them to disintegrate and release analyte molecules. The volatilized analyte molecules are then analyzed by mass spectrometry.
A mass spectrometric technique that is used for the analysis of a wide range of biomolecules, such as glycoalkaloids, glycoproteins, polysaccharides, and peptides. Positive and negative fast atom bombardment spectra are recorded on a mass spectrometer fitted with an atom gun with xenon as the customary beam. The mass spectra obtained contain molecular weight recognition as well as sequence information.
