This is a data table of possible ion structure-formula for integer m/z values of ions formed in mass spectrometers and is designed for advanced level pre-university chemistry students. (a) …

suggest possible molecular formulas for a compound, given the m/z value for the molecular ion, or a mass spectrum from which this value can be obtained.

Calculation Example: In mass spectrometry, the mass-to-charge ratio (m/z) of an ion is measured. The mass of the ion can be calculated using the formula Mass = m/z * Z, where Z is the …

Enter the mass (in Daltons) and charge (in elementary charge units) into the calculator to determine the mass-to-charge ratio (m/z value) of an ion. The m/z value is a dimensionless …

The M/Z (mass-to-charge) ratio is a key parameter in mass spectrometry, used to identify ions based on their mass and charge. It is vital for understanding the behavior of ions in a mass …

Alpha-cleavage gives ions at m/z=57 & 85 Da. The McLafferty rearrangement on the acid side generates a m/z=116 ion. Subsequent rearrangement on the alcohol side generates m/z=60 …

Depending on the type of mass spectrometry, ions will have different amounts of charge. For example, MALDI results in single charges, but ESI of large molecules will have greater …

Free online mass spectrometry m/z calculator. Calculate isotope patterns, molecular mass, and fragment analysis for mass spectrometry.

The number of electrons removed is the charge number (for positive ions). m/z represents mass divided by charge number and the horizontal axis in a mass spectrum is expressed in units of …

The most abundant ion of the molecule under mass spectrometry investigation is usually given an arbitrary abundance value of 100, called the base ion peak, and all other abundances …
