Calculating uncertainties

Calculating uncertainties

Posted by Jireh Gordon on Nov 28, 2021 9:24 pm

Hello, I'm looking for some help with an uncertainty issue.
I have been trying to assign numbers to bottom up or type B uncertainties. For calibrations, say of a GC, I can calculate the uncertainty for the concentration of each standard but I am unsure how to combine these to apply them to the results found using said calibration. The uncertainty associated with the lower concentration standards are often much higher but will have less impact on the sample result. 
Has anyone else tackled this issue?

It's pretty frustrating when the computing hardware is out of order, right?

Looks like you are on the verge of another breakthrough at this point.
