Molecular Weight Determination

Molecular weight is a critical property of a chemical, particularly for polymers. Element Midland has extensive experience and comprehensive tools for measuring molecular weight of all types of compounds and polymers. We can supply results to aid in problem solving, unknown identification, manufacturing support, or product deformulation.

How We Find Molecular Weight

Depending on the sample material, we can find molecular weight through a variety of techniques. Mass spectrometry is one technique that can be used to determine what molecular weight and molecular structure of small molecules are. Using a direct infusion method, samples can be introduced directly to the detector to confirm the molecular weight of a known material, or provide structural characterization of an unknown.

Molecular weight information of polymers can be determined using techniques such as viscosity and size exclusion chromatography. In order to perform molecular weight determinations of polymers, it is necessary to understand the solubility of a given polymer.

Element Midland has state-of the-art equipment, and the knowledge and experience to provide you with molecular weight information of your sample material, whether it is a small molecule material or a polymer.

What is Molecular Weight?

Molecular weight is the sum of the atomic masses in a molecule.

How Do You Calculate Molecular Weight?

Molecular weight is calculated by adding the atomic weights of all the elements in a molecule and multiplying each by the number of atoms of that element in the molecule.
