"This interlaboratory study helps to ensure comparability of routine data produced by Water Quality Branch laboratories and it also forms part of Phase II of the continuing specification program. It generates additional specification data on fourteen (14) analytical methods for trace metals by direct aspiration technique. Specification statements permit meaningful interpretation of historical, present and future data produced by laboratories using lWD analytical methods"--Executive summary.
