Package info

Price: 1 525 SEK / sample
Std. response time: 15 work days
Discount group: 1
Sample type: Soil, sludge and sediment
Analysis type: Elements
Sample amount: min. 5 g dry matter
Container: 100 ml plastic jar
Method: Digestion: For the determination of As, Cd, Co, Cu, Hg, Ni, Pb, S and Zn, the sample is dried at 50°C and leaching in 7M HNO3 for sludge/sediment, HNO3/H2O2 for soil. (The concentrations are recalculated to DW 105°C.) Other compounds are determined after fusion with lithium methaborate followed by dissolution in diluted nitric acid.
Express: Yes
