WAC analysis ALS Environmental

The new requirement for method BS EN 12457-2 allows a single stage leaching process (moisture corrected 101 liquid to solid ratio leaching step for 24 hours). This will mean that by selecting the BS EN 12457-2 method, ALS Environmental will be able to turnaround the analytical WAC reports quicker than the previous 2-stage leaching procedure
