What does FWDM mean in UNCLASSIFIED

FWDM stands for Fragment Weight Distribution Map. This is an analytical technique used by researchers to gain insight into the relative proportions of different components comprising a sample.

FWDM utilizes a visual representation of mass spectrometry data produced from samples to generate a graph that displays the relative amounts of each component present in the sample. The graph displays both major and minor compounds or fragments in relation to one another, allowing for comparison between various substances.

Using this technique, researchers are able to obtain detailed molecular weight distributions (MWDs) and detect minor components with lower concentrations than those detected using other analytical techniques. Additionally, this method can also be used to study ratios between chemical species present in a given sample.

This technique can be applied to many different types of samples including proteins, polymers, molecules, lipids, and more.

Some benefits include its ability to identify even trace amounts of components within samples as well as its non-destructive nature which allows for future reanalysis if needed. Additionally because this procedure does not require any prior knowledge about the nature or composition of the sample it makes it relatively easy-to-use compared to other analytical techniques.
