This page looks at the information you can get from the mass spectrum of an element. It shows how you can find out the masses and relative abundances of the various isotopes of the element and use that information to calculate the relative atomic mass of the element.
29 Αυγ 2023 · It shows how you can find out the masses and relative abundances of the various isotopes of the element and use that information to calculate the relative atomic mass of the element. It also looks at the problems thrown up by elements with diatomic molecules - like chlorine, Cl 2.
3 Δεκ 2019 · The presence of five peaks for chlorine shows the ratio of heights for peaks 1 and 2 is 3: 1. For bimolecular ions, ¾ of the chlorine isotopes are Cl 35 and ¼ of the isotope of chlorine is cl37. The mass spectrum of an organic compound having chlorine atoms also show different mass spectrum.
27 Μαΐ 2024 · interpret the fragmentation pattern of the mass spectrum of a relatively simple, known compound (e.g., hexane). use the fragmentation pattern in a given mass spectrum to assist in the identification of a relatively simple, unknown compound (e.g., an unknown alkane).

7 Δεκ 2021 · Ultrahigh resolution mass spectrometry (UHR-MS) is commonly used to characterize natural organic matter (NOM). The complexity of both NOM and the data set produced make data visualization challenging.
15 Αυγ 2020 · Overall assignment accuracy for 8719 NOM-like emerging chemicals with known molecular formulae (mass range from 68 Da to 1000 Da) was highest (94%) for TRFu. Further, TRFu showed up to 99.1% formula assignment ratio for a total 76,880 UHR-MS peaks from 35 types of NOM (e.g., aquatic, soil/sediment, biochar).
