Research of materials and environmental protection

Talum Inštitut, d.o.o (Talum Institute Ltd)., is a subsidiary of the group Talum, d.d. The institute performs laboratory testing in the production of primary aluminium and aluminium products and in the production of environmental management.

In accordance with the international standards ISO/IEC 17025, ISO 9001, ISO 14001, ISO 45001, IATF 16949 and TISAX and powers given by MOP ARSO (Ministry of the Environment and Spatial Planning, Slovenian Environment Agency) it provides an excellent quality of service with sustainable development principles.

Accredited procedures in the field of waste water and groundwater, air emissions, waste, soil and aluminium and aluminium-silicon alloys take place in accordance with the standard DIN EN ISO/IEC 17025. The Slovenian accreditation granted the company the accreditation certificate LP-045, which applies along with the annex containing list of accredited procedures. Talum Inštitut is registered in the record of operators of research and development activities under the number 3439 with the Public Research Agency RS. We collaborate with internationally recognized public and private research and development institutions and other accredited and non-accredited business partners.

Laboratory research

Main activities are testing of products made of aluminium and aluminium alloys, environmental parameters (water, air, waste, groundwater, soil, control of equipment for continuous measurements, immissions), raw materials and processing characteristics of different materials in the production of aluminium, evaluation of results and preparation of the assessment according to specifications, norms and laws.

We are the first industrial laboratory in Slovenia, which is accredited (LP-045) for optical emission spectrometry (OES) for aluminium and aluminium-silicon alloys.

In the laboratory, we analyse a variety of materials and products:
- products made from aluminium and aluminium alloys,
- electrolyte baths,
- carbon materials,
- fluorine salts,
- alumina,
- silicon,
- master alloys for the production of aluminium alloys,
- surface and waste water,
- groundwater and soil,
- emissions and immissions in the air,
- waste,
- soil,
- vegetation,
- zeolite and water-glass,
- ferrosilicon,
  and others.

The most important areas of testing methods (ISO, EN, DIN, etc.), based on various measurement principles are as follows:

a) spectroscopic analyses:
- optical emission spectrometry (OES) of aluminium and aluminium alloys
- X-ray diffraction (XRD) of solid materials,
- X-ray fluorescence spectrometry (XRF) of electrolyte bath, fluorine salts, oils, and emulsions,   ferrosilicon, alloys and master alloys of aluminium;
- atomic absorption spectrometry (AAS),
- spectrophotometry (UV/VIS) and ion chromatography (IC) of prepared solutions;
- ion coupled plasma with mass spectrometry (ICP-MS) with laser ablation for the determination   of metallic elements in solutions;
- gas chromatography with mass spectrometry (GC-MS) for the determination of organic substances in waters;
- infra-red spectroscopy (FTIR), for the identification of oils and emulsions;

b) Mechanical and physical examinations:
- Mechanical and physical examinations:
- specific surface of the material (BET),
- flexural and compressive strength of carbon material,
- electrical resistivity, air permeability, apparent and real density, air and CO2 reactivity,
- thermogravimetric analysis (TGA) of carbon and other materials,

c) Metallographic examinations: Microscopy with optical microscopes by e-image processing and on this basis:
- various inclusions are identified,
- the size and number of crystal grains,
- inverse segregation and Bergman zones are determined.

d) Investigation and monitoring of states of various oils:
- hydraulic oils for smooth and reliable operation of the hydraulic system,
- rolling oils and emulsions to support the smooth functioning of the production and
- transformer oils for the uninterrupted transformer operation.

Organizing interlaboratory
comparative tests

Talum Inštitut has several years of experience in the field of its activity. These enable it to organize inter-laboratory comparisons to verify the competence of laboratories in the field of emissions into the air and the chemical composition of aluminium and aluminium alloys.

The purpose of interlaboratory comparisons is that each laboratory in direct comparison with other laboratories demonstrates its ability to perform specific tests, measurements or calibrations and the performance and satisfactory performance in the field of laboratory testing.

Interlaboratory comparisons are organized in accordance with ISO 13528 and ISO/IEC 17043.

In the Republic of Slovenia, a technical committee for air emission is organized with active members of Talum Inštitut, Slovenian Accreditation, Slovenian Environment Agency, National Laboratory of Health, Environment and Food and companies IVD Maribor, RACI and Eurofins Erico Slovenia.
