2.3.2. Sample preparation of process streams for laboratory analysis
Sample preparation of the process streams for their laboratory analysis was done according to EN 15443. The purpose here was to reduce the original size (mass) of combined samples of process streams (see Table 1) to a laboratory test portion size (mass) by not changing its original composition during each step of sample preparation. Sample preparation of the combined samples of process streams for their laboratory analysis was done in two stages; sample preparation before sending samples to laboratory and sample preparation in the laboratory.
