TThe expression CMS is a single quadrupole mass spectrometer, equipped with ESI and APCI probes, switchable with minimal effort. The instrument has a mass range of m/z 10 to m/z 1,200, and a ...

Normally, 1 mg is enough for ESI. Impure samples likely produce poor spectra. In addition to providing “extra” peaks in a mass spectrum, which may be confusing, they may mask the sample peaks in ...

Mass spectrometry has become the standard tool ... iodoacetamide adducts as ubiquitination sites is. The iodoacetamide peak has roughly 20–50% of the intensity of the true ubiquitinated peaks ...

Researchers leveraged the advantages of thermodesorption, followed by comprehensive two-dimensional gas chromatography ...

Two-dimensional liquid chromatography (2D-LC) coupled to mass spectrometry (MS) has been used to separate proteins in the ...

The Waters G2 Synapt is a state of the art high performance ion mobility orthogonal mass spectrometer with nano-spray and MALDI ... a large number of spectra (12,500 amu/sec) across every GC peak ...
