Isotope Ratio Calculator

Formula

The formula to calculate the isotope ratio (ISR) is:

$ISR = \frac{I}{RI}$

Where:

$ISR$ is the isotope ratio.
$I$ is the quantity of the first isotope.
$RI$ is the quantity of the reference isotope.

What is an Isotope Ratio?

An isotope ratio is the ratio of the quantity of one isotope to the quantity of a reference isotope. This ratio is used in various scientific fields, including geology, chemistry, and environmental science, to study processes and changes in natural systems.

Example Calculation

Consider an example where:

Quantity of First Isotope (I): 50 units
Quantity of Reference Isotope (RI): 25 units

Using the formula to calculate the isotope ratio:

$ISR = \frac{50}{25} = 2$

This means that the isotope ratio for this example is 2.
