Tony's Tech Tip: Why is there a wide range of acceptance for reference materials?

We get this question often.

Now the sample is very well characterized by HPLC methods, however, to account for those other sources of variance, a wider margin of error is given to the individual technician to be able to demonstrate proficiency when using that reference material.
