m/z Calculator

Formula

The formula to calculate the m/z value is:

\[ \frac{M}{Z} \]

Where:

\(M\) is the mass of the ion in Daltons (Da)
\(Z\) is the charge of the ion in elementary charge units (e)

What is an m/z Value?

The m/z value is a dimensionless quantity that represents the mass-to-charge ratio of an ion. It is a fundamental parameter in mass spectrometry, which is a technique used to measure the masses of particles, the elemental composition of a sample, and the chemical structures of molecules. The m/z value helps in identifying and quantifying molecules in a sample.

Example Calculation 1

Let's assume the following values:

Mass of the Ion (M) = 1000 Da
Charge of the Ion (Z) = 2 e

Using the formula:

\[ \frac{1000}{2} = 500 \]

The m/z Value is 500.

Example Calculation 2

Let's assume the following values:

Mass of the Ion (M) = 1500 Da
Charge of the Ion (Z) = 3 e

Using the formula:

\[ \frac{1500}{3} = 500 \]

The m/z Value is 500.
