Metals in soil, sludge and sediment

 
 
 
M-1a Metals in soil and sediment (accredited)
As (10) Ba (0.2) Be (0.1) Cd (2) Co (2)
Cr* (2) Cu (2) Fe (10) Li (0.4) Mn (0.5)
Mo (2) Ni (2) P (6) Pb (10) Sn (5)
Sr (0.2) V (2) Zn (1)    
Figures in brackets denote limits of quantification in mg/kg dry weight. Minimum sample amount: 1 g dry matter. Price includes digestion.

* May be supplemented with determination of Cr(VI).

 

M-1a may be supplemented with additional elements.

Digestion: The sample is dried at 50°C and leached in 7 M nitric acid in closed teflon vessels in a microwave oven (concentrations are corrected to dry weight 105°C.) For soil samples, nitric acid/hydrogen peroxide is used instead of 7 M nitric acid.

Digestion using 7M nitric acid can alternatively be performed in autoclave. Please contact the laboratory for more information.

Supplementary anaysis
methyl mercury (0.05)
Figures in brackets denote limits of quantification in ng/g. Minimum sample amount: 1 g.

Digestion: The sample is dried at 50°C and leached in nitric acid/hydrogen peroxide in closed teflon vessels in a microwave oven (concentrations are corrected to dry weight 105°C.)

RUSH SAMPLES
When results within 24 hours are requested, drying and sieving prior to subsampling is omitted. For non-homogeneous samples, drying and sieving is recommended in order to achieve a representative subsampling. Results can then be received within 48 hours.

Supplementary anaysis
methyl mercury (0.05)
Figures in brackets denote limits of quantification in ng/g. Minimum sample amount: 1 g.

Figures in brackets denote limits of quantification in mg/kg dry weight. Minimum sample amount: min 1 g dry matter. Price includes digestion.

* May be supplemented with determination of Cr(VI).

  M-2 may be supplemented with additional elements. Supplementary element within the accreditation: Ba, Be, Fe, Li, Mn, Mo, P, Sr.
Hg can be determined by AFS as a supplementary element (0.01 mg/kg TS).

Digestion: The sample is dried at 50°C and leached in 7 M nitric acid in closed teflon vessels in a microwave oven (concentrations are corrected to dry weight 105°C.) For soil samples, nitric acid/hydrogen peroxide is used instead of 7 M nitric acid.

Accredited analyses are marked in bold. Figures in brackets denote limits of quantification in mg/kg dry weight. Minimum sample amount: min 5 g dry matter. Price includes digestion. Note: Samples must be ground before analysis.

* May be supplemented with determination of Cr(VI).
 

MG-1 may be supplemented with additional elements.
Hg can be determined by AFS as a supplementary element (0.01 mg/kg TS).

Digestion: The sample is dried at 50°C and leached in 7 M nitric acid in closed teflon vessels in a microwave oven (concentrations are corrected to dry weight 105°C.) Other elements are determined after fusion with lithiummetaborate and dissolved in dilute nitric acid.

Digestion using 7M nitric acid can alternatively be performed in autoclave. Please contact the laboratory for more information.
