Recalling what you learned in algebra class may be the best way to explain Relative Standard Deviation (RSD). RSD is the Standard Deviation from a pool of data over the average, thus the standard deviation relative to the average or the relative standard deviation.

In the video below, Chemical Solutions President Brian LaBine offers a primer on RSD covering answers to questions such as:

- What’s the relation to elemental impurity testing and validation?
- How do we get the calculation when we tell you what an RSD is?
- Where is RSD applied?
- What are the variations of RSD?
