Descripción del servicio
A procedure for dissolving the sample will be used to allow the determination of the elements of interest considering the nature of the sample and the fraction to be analyzed:
WATER SOLUBLE FRACTION
Extractions with water in ratios 1:5, 1:10, UNE-EN 450-1:2013 Fly ash for concrete. Part 1 Annex C. Samples must be ground to test size. If this is not the case, the following must be requested: Sample treatment: crushed variant: Grinding in an agate ring mill (<100g),
- Standards UNE-EN 12457-1 to 4:2003. Waste characterization. leaching. Conformity test for leaching of granular waste and sludge. A specific granulometry is required. Consult with the Laboratory.
EXTRACTABLE FRACTION IN ACID MEDIUM
- Acids used individually: hydrochloric acid, nitric acid, etc.
- Acid mixtures: hydrochloric acid and nitric acid, nitric acid and hydrogen peroxide,
Samples must be ground to test size. If this is not the case, the following must be requested: Sample treatment: crushed variant: Grinding in an agate ring mill (<100g),
OVERALL CONTENT
- Dissolution of the samples with nitric acid, hydrofluoric acid and perchloric acid.
Samples must be ground to test size. If this is not the case, the following must be requested: Sample treatment: crushed variant: Grinding in an agate ring mill (<100g),
The solutions will be analyzed with the most convenient techniques according to the requested elements: AAS (Provision: Element analysis: FAAS Variant: Determination of metallic elements by AAS in liquid samples), ICP-AES (Provision: Element analysis: ICP-OES, Variant: Det. elemental majority and traces ICP-ÁES liquid sample) or ICP-MS (Provision: Element analysis: ICP-MS, Variant: Determination of trace elements by ICP-MS (liquid sample)).
The applicant must indicate the dissolution procedure and the elements to be determined.
Other sample preparations for dissolution are:
- The calcination and subsequent acid dissolution of the residue can be consulted in the Service: Lost on fire. Variant: Preparation of pharmaceutical products by calcination.
- The melting and subsequent acid dissolution of the melt can be consulted in the Service: Sample treatment: Melting. Variant: Fusions for determinations by AAS, ICP-AES or ICP-MS.
For any other procedure, consult the Laboratories.
