What is Isotopic standard?

An isotopic standard is a substance that is used as a reference to calibrate and compare isotopic measurements. These standards are typically well-characterized and contain known amounts of isotopic elements, allowing scientists to determine the isotopic composition of unknown samples by comparison. Isotopic standards are crucial for ensuring the accuracy and consistency of isotopic measurements in various fields of science.

What is sulfur Isotopic standard?

A sulfur isotopic standard is a reference material used for measuring and calibrating the isotopic composition of sulfur in samples. It helps researchers ensure the accuracy and precision of their sulfur isotope measurements by providing a known reference point. These standards are often characterized by their isotopic composition and are used in various fields such as geology, environmental science, and biology.


How many isotopic kinds of HCl are there?

There are two isotopic kinds of HCl: hydrogen chloride (HCl) and deuterium chloride (DCl). Deuterium chloride is composed of deuterium, an isotope of hydrogen with one proton and one neutron in its nucleus, instead of the more common isotope of hydrogen with just one proton.


Which gas is heaviest nitrogen hydrogen or oxygen?

Nitrogen is heavier than hydrogen but lighter than oxygen. In terms of molecular weight, nitrogen has a molar mass of about 28 g/mol, oxygen has a molar mass of about 32 g/mol, and hydrogen has a molar mass of about 2 g/mol.
