The exact mass of an isotopic species (more appropriately, the calculated exact mass) is obtained by summing the masses of the individual isotopes of the molecule. For example, the exact mass of water containing two hydrogen-1 (1 H) and one oxygen-16 (16 O) is 1.0078 + 1.0078 + 15.9949 = 18.0105 Da Search for Species Data by Molecular Weight. Note: This search is by molecular weight based on single (most-abundant) isotope atomic masses. These weights may vary significantly from molecular weights based on average atomic masses.

The exact mass database, which comprised molecular formulae, retention time and accurate mass, was created using data from 41 benzodiazepines. It became clear that LC separation is indispensable in accurate mass measurement, such as metabolites of etizolam and triazolam which calculated exact mass is approximated. Accuracy was increased by using TOF-MS with an exact mass database for the. An automated molecular-feature database (MFD) consisting of the exact monoisotopic mass of 100 compounds, at least one exact mass product ion for each compound, and chromatographic retention time were used to identify pesticides in food and water samples. The MFD software compiles a list of accurate mass ions, excludes noise, and compares them with the monoisotopic exact masses in the database Mass spectrometry is an analytical tool useful for measuring the mass-to-charge ratio (m/z) of one or more molecules present in a sample. These measurements can often be used to calculate the exact molecular weight of the sample components as well. Typically, mass spectrometers can be used to identify unknown compounds via molecular weight determination, to quantify know This report describes an exact mass database of 81 pesticides for use with gas chromatography high resolution mass spectrometry (GC-HRMS). For each pesticide the chemical formula and molecular weight is listed as well as the formula and exact mass of a number of characteristic fragment ions. The database was updated in 2015 with exact mass fragments of 28 pesticides and together with the 53. Table 1 shows the number of nucleons and mass data for the atoms mentioned above, plus some others that are found in organic compounds.

You should use the exact mass, and in almost all cases the exact mass of the monoisotopic peak (i.e. the monoisotopic mass). The molecular weight, or molar mass, is the sum of the abundance weighted average of all isotopes of each element in the molecule. Since the isotopologues are measured separately in mass spectrometry (resulting in those characteristic isotope patterns for individual. This module contains the exact mass data from the table of the isotopes. It has an exportable function, isotope_mass, which returns the mass of an atom in mass units given its mass number (A) and atomic number (Z); and a function isotope_abundance which returns a table with the natural abundance of the isotopes given an element symbol The mass calculator on the right may be used to calculate the exact mass of a molecule based on its elemental composition. Simply enter an appropriate subscript number to the right of each symbol, leaving those elements not present blank, and press the Calculate button. Only the mass of the most abundant isotope, relative to C (12.0000), is used for these calculations. For compounds of.
