The Laboratory has many years of experience in testing elements of the natural environment, state of the environment, industrial products and wastes, etc. It is the first laboratory of waste testing in Poland which has been accredited by the Polish Centre for Accreditation.
The Laboratory conducts work within the framework of own, targeted and ordered research projects regarding new development and adaptation of existing analytical methods for analysing environmental samples and for analysing samples related to the industry.
The scope of activity of the Laboratory of Solid Waste Analyses includes various types of research objects, such as environmental samples (lands/soils), industrial solid wastes, solid fuels, building materials, filter beds and materials for contact with drinking water).
It should be added that expertise, opinions, assessments for industry, mining and environmental services are carried out in cooperation with the Division of Ecological Researches and the other laboratories of the Department of Environmental Monitoring GIG, in the field of, among others, soil and land pollution, environmental impact, or the use of wastes, e.g. on the surface of the earth and in the underground mining excavations.
The competent and experienced staff, application of the principles of professional laboratory practice and modern test and measurement facilities enable a wide range of tests, such as physicochemical analysis, technical analysis, determination of basic composition and trace elements as well as rare earth metals.
Samples delivered to the Laboratory should be protected against the possibility of moisture or secondary contamination (a sealed foil bag, jar, plastic container, etc.) and provided with a label containing basic identification data. The parcel should also contain the order (letter) for testing.
As the amount of sample delivered to the Laboratory and the time of analysis is due to the set / predicted scope of tests, the Customer should agree in advance the sample size with the Head of Unit.
The Laboratory of Water And Wastewater Analyses conducts research activities related to the development of new research procedures used in the analysis of natural and leachate waters with a high content of solutes.
As part of service work, the Laboratory performs annually over 3,000 physical and chemical analyses of water and wastewater in various tested materials, meeting the requirements of customers from the mining, energy, food, pharmaceutical, environmental protection, and other industries.
The subject of tests in the laboratory are drinking water, curative and thermal waters, surface waters, underground and industrial waters, leachate waters and wastewater (industrial, social and municipal facilities).
More than 100 physicochemical parameters are determined in the samples tested, using a variety of measurement techniques, including very modern ones, e.g. ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry), ICP-MS (Inductively Coupled Plasma - Mass Spectrometry), high temperature distribution techniques, IC (Ion Chromatography), flow techniques - injection FIA (Flow Injection Analysis) and continuous with stream segmentation SFA (Segmented Flow Analysis) with spectrophotometric detection.
The Laboratory of Water And Wastewater Analyses also carries out an assessment of the corrosive aggressiveness of water against concrete and steel on the basis of the analysis and tests carried out of the water for mixing concrete. The Laboratory conducts migration testing, determining the impact of materials on drinking water, jointly with the Laboratory of Solid Waste Analyses. The Laboratory performs also tests of food, road and bath salts and, to a limited extent (primarily metal content), tests of various foodstuffs.
Samples for testing taken by the Customer may be sent by courier to the address of the Laboratory or delivered in person to the same address.
The Laboratory conducts research and service activities in the broadly understood mineral engineering. It covers issues related to the identification of the chemical and mineral composition as well as testing the technological characteristics of minerals and wastes.
The Laboratory is equipped with a modern digital scanning electron microscope Hitachi model
SU-3500N with an EDS attachment and a sputter, as well as an analyser of size, shape, and number of particles Morphologi G3S-ID, made by Malvern, with a Raman spectroscopy attachment for analysis to identify the chemical composition.
We carry out technological works aimed at defining and optimizing technical and technological conditions for valorisation and obtaining commercial products from minerals and wastes.
The technical equipment in the Laboratory and the staff experience allow testing and optimization of various industrial unit processes on a laboratory scale. We have the technical capabilities to carry out verification tests of suspension dewatering processes in a sedimentation-filtration centrifuge and a chamber-membrane press with blowing, on a full industrial scale.
We develop and consult concepts of technologies for the enrichment of mineral raw materials, instructions for running landfills, expertise in achieving the assumed ecological effects of investments, as well as tools and instruments supporting waste management.
We also deal with active social and labour market policy, strategic directions of development of communes and counties of the Silesian Voivodeship, demographic conditions of social policy, etc.

The Laboratory of Organic Compounds Analyses is involved in broadly understood environmental tests. We conduct research and service activities for environmental engineering, waste management, mining, construction, energy, chemical industry, food industry, and agriculture. We also do
non-commercial research that requires a scientific approach to the problem. The Laboratory cooperates with the Lab of Ecological Analyses and other laboratories of the Department of Environmental Monitoring.
The scope of activity of the Laboratory of Analysis of Organic Compounds includes testing of samples with various matrices: water, sewage, soil and land, waste, building materials, liquid mixtures, plants, and food products as well as water extracts/extracts.
We are a qualified group of chemists with many years of experience, and professionalism is our undeniable advantage. Over the years, we have created a constantly improving research team, open to new innovative analytical solutions. We guarantee reliable results for the most demanding customers.
Requirements for the execution of tests, in particular, the method of sampling, preservation, and transport to the Laboratory are strictly defined and require clarification by the Laboratory (email or telephone contact).
