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.
3 Δεκ 2019 · The mass spectrum of chlorine is good example of molecular element. Chlorine has two stable isotopes; chlorine-37 (25%) and chlorine -35 (75%).There are five main peaks of isotopes of chlorine of various isotopic monatomic ions. [37 Cl 2] + m\z = 74 ( molecular ion) [37 Cl 35 Cl] + m\z = 72.
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).
10 Μαρ 2022 · Mass spectroscopy can be used to find the relative abundance of the isotopes experimentally; The relative abundance of an isotope is the proportion of one particular isotope in a mixture of isotopes found in nature. For example, the relative abundance of Cl-35 and Cl-37 is 75% and 25% respectively
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.
Runoff of organic chlorine from the lower layers of soil is about 0.01 g/m2yr, much smaller than from the top layer (0.2 g/m2yr). In fact, the concentration of organic chlorine decreases with depth as shown in Figure 3 for Skullebo (south of Linköping, S) and Klosterhede (DK). Figure 3.
30 Δεκ 2020 · In this study, a novel method using water extraction coupled with concatenated ion exchange chromatography for the extraction of hydrosoluble chlorine in soil samples is established for the determination of chorine isotopes by thermal ionization mass spectrometry.
