Brandenburg As promised I would -come back in February with a proposal for uniform sampling and analysis procedures for C-8* The reason for this is that sofar, most C-8 results have been generated in a non-routine way. The choice of sample-taking equipment, sample preparation, and actual analytical technique was often based on individual preference. Although the analytical techniques can easily be verified by using standard solutions, this is not the case with the Sample collection, concentration and preparation. Therefore special emphasis should be given to the way of sampling and preparation. we want to be able to compare results from different sites, and -most importantly- to compare last years1 results with next years' result. This i3 only possible if we use the same methods all the time. Attached is a matrix with 4 columns. The first column lists the various samples we may have to deal with. Column "C" indicates the proposed sampling Collection /Concentration method* Column "P" is for the sample Preparation, and column "A" is for the Analysis, This is just a first shot so if you have other ideas or additions, please don't hesitate to let me know. Also 1 should like to know if Parkersburg and MDF have value for this global approach, and are willing to adjust their procedures where necessary to achieve some degree of global uniformity. Please answer before April 1. beet regards, Rik Brandenburg EID936951 RJZ012172 A T T I .txt DRAFT PROCEDURE FOR C-8 SAMPLING AND ANALYSIS I.
