Abstract |
A collaborative test of EPA Method 104 for beryllium was conducted at the Coors Porcelain Company in Golden, Colorado during the period of December 4-21, 1973. The test comprised 13 runs, each on a different day, where four different collaborative organizations sampled simultaneously over the same 30 point traverse in the stack, with each point being sampled 8 minutes by each collaborator. In addition, the collaborators analyzed simulated standard samples prepared by the National Bureau of Standards. A statistical analysis of the data provides estimates of the variance of repeated observations per collaborator, the variance between collaborators and the accuracy of the method. |
