| Abstract |
Sample type II, BD-2 is composed of water to be analyzed for dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, ammonia nitrogen. Participant laboratories analyzed samples of water analytically. Standard deviations were calculated and are presented. Results of each analysis are presented including the methods used. Finally comments on the methods are presented as are summary data tables. It is hoped that the following are provided: a statistical evaluation of procedures, the opportunity for laboratories to be compared, exchange of information, evidence suggesting methods requiring further development, and a framework for broad evaluations of new analytical methods. |
