First draft C-8 sampling + analysis procedure
Tot see distribution list
From;R.A. Brandenburg
AS promised I would -come back in February with a proposal for uniforni sampling and analysia procedures for C-8. The reason for thta is that sofar, (noett C-8 results hav been generated in a non-routine way. The choice of sample-taking equipmenty sample preparation, and actual analytical technique was often based on individual preference. Although the analytical techniques can easily be verified by using standard solutionB, this is not the oase with the eatftple collection, concentration and preparation. Therefore special emphasis flhould b& 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 years' results with next years'
result. This is only posaible 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 ie just a first shot so if you have other ideas or additions, please don't hesitate to let me know. Also I should like to know if
Parkersburg and HDP 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
