Factors affecting reactivity in ammonia chemical
Quadrupole mass spectrometric (QMS) analysis of small amounts of inclusion fluid ( < 1 milligram) released by crushing and decrepitation requires methods to: (1) determine the amount of molecular fragmentation and the relative sensitivity to water and other gases, (2) evaluate differential adsorption of gases in the analytical system, (3...

Abstract. Numerous experimental factors are shown to significantly influence the spectra obtained when bacteria are analyzed by MALDI TOF/MS. Detailed investigation of the instrument parameters and sample preparation are all shown to influence the spectra.
- Some Common Ions. There are a number of ions commonly seen in mass spectrometry that tell you a little bit about the structure. Just like with anions, there are a couple of common factors

- After molecules are ionized in a mass spectrometer, they become radical cations that can then be sorted and weighed. Some of these radical cations can also rearrange after being ionized. The most famous rearrangement is called the McLafferty rearrangement. A radical cation is a cation with an
- One of the main limitations to the use of direct coupling of headspace mass spectrometry (HS-MS) for the quantitative determination of analytes in a sample is related to factors affecting the
