Elution of solids - percolation method (DIN 19528)
Parameters (quantitative): chromium (1st percolation) [µg/l], molybdenum (1st percolation) [µg/l], vanadium (1st percolation) [µg/l], sulphate (1st percolation) [mg/l], PAH15 (1st percolation) [µg/l], chromium (2:1-column percolation) [µg/l], molybdenum (2:1-column percolation) [µg/l], vanadium (2:1-column percolation) [µg/l], sulphate (2:1-column percolation) [mg/l], PAH15 (2:1-column percolation) [µg/l]
Article Number: 2011277
Description: The percolation should be carried out using the detailed method according to DIN 19528. The individual values of the eluates and the calculated 2:1 column percolate value are queried.
