CGS Central Laboratory

The Central Laboratory contributes significantly to the basic and applied research of the Czech Geological Survey (CGS), its activities help to fulfil the Long-term Concept of Development of a Research Organisation (DKRVO) and to ensure the performance of the State Geological Service. The laboratory has been accredited since 1993 by the Czech Institute for Accreditation (CIA) according to the ČSN EN ISO 17025 standard. It offers its professional services to internal and external customers from major scientific and state institutions, private entities and small customers. The laboratory specializes mainly in providing laboratory services in the field of inorganic and organic analysis of geological materials, inorganic analysis of natural waters and chemical analysis of gases including their sampling. In case of customer's request, assistance with the selection of a suitable method is a matter of course.

The CGS Central Laboratory has two separate facilities:

  • Central Laboratory - Prague - Geologická 6, Prague 5
  • Central Laboratory - Brno - Leitnerova 22, Brno

The Prague department deals with inorganic analysis, the main matrices analysed are mainly geological materials, sediments, soils, but also less traditional matrices such as plant material, peat or wood.
The main customer requirement is silicate analysis, which provides a basic picture of the chemical composition of a given sample. The laboratory also analyses various types of surface and precipitation water.
The Brno site deals with organic and gas geochemistry.
It determines the content of organic and mineral carbon, total sulphur and persistent organic pollutants in sedimentary rocks and soils. In selected rock and oil samples, it determines the molecular composition of extractable substances, especially biomarkers indicating the biological origin of organic matter.
In addition to the analysis of solids, it performs sampling and subsequent analysis of soil, spontaneous and landfill gases.

 Certification

Accreditation of a laboratory means formal recognition of the professional and organisational competence to perform a specific service as described in the laboratory's scope of accreditation. The introduction of accreditation into laboratory practice is therefore an initiative towards transparency of activities and is linked to the need for laboratories to improve and make their processes more transparent. Continuous improvement of laboratory processes and satisfying the needs of stakeholders is a prerequisite for the successful perception of the laboratory by customers, employees and higher authorities.

Of course, you can also complain about any part of the work done by the laboratory. Customers can complain verbally or by sending an e-mail to tereza.grabmullerova@geology.cz or daniela.ocaskova@geology.cz.

Analysis of solid samples – Prague

For solid samples, the laboratory offers mainly silicate analyses, determination of trace elements and REEs, the analyses also include suitable decomposition of samples prepared at the homogenization facility.
The laboratory provides services mainly to in-house staff, cooperation with scientific and teaching departments can be arranged or analyses can be carried out as a commercial contract.

Range of services

  • silicate analyses - determination of SiO2, TiO2, Fe2O3, FeO, Al2O3, SrO, BaO, Li2O, MnO, CaO, MgO, Na2O, K2O, P2O5, moisture, bound water,CO2, Ctot,Stot, F and loss by drying or annealing. The laboratory offers four types of silicate analyses – total, simplified, technical and modified, which differ in the number of components analysed and the total sum of all components. The individual determinations included in the silicate analysis can also be ordered individually
  • Soil analysis of leachate in BaCl2, in which the total acidity and exchangeable Al can be calculated. In addition, the pH in aqueous leachate, the pH in KCl leachate is determined. In the Mehlich III leachate, the concentrations of P2O5 can be determined spectrophotometrically.
  • trace elements can also be determined by the XRF-WDX method using a Rigaku X-ray spectrometer without the need for sample digestion. From the pressed tablet, the elements (As, Ba, Bi, Ce, Co, Cr, Cu, Ga, La, Mo, Nb, Nd, Ni, Pb, Rb, Sc, Sn, Sr, Th, Ti, U, V, W, Y, Zn, Zr) are determined. The limit of quantification for this analysis is in units of ppm
  • inorganic analysis of special materials such as wood, peat, needles, leaves
  • determination of REEs

Analysis of water – Prague

The laboratory performs complete analyses of various types of surface and rainwater. The analytical methods used have been tested for a long time on the CGS specialist programmes that monitor the status of selected river basins in the Czech Republic.

Range of services

The basic water analysis includes determination of Li, Na, K, NH4+, Mg, Ca, Mn, Zn, Fe, Al, SiO2, pH, F, Cl, NO3, HCO3, SO4, conductivity, alkalinity, pH and total phosphorus.
Among the trace elements, Al, As, Be, Cd, Co, Cr, Cu, Mo, Ni, Pb, V and Hg are determined in μg/l concentrations. Other selected elements can also be determined by ICP-MS in acidified samples. For the determination of organic carbon and total nitrogen in waters, the laboratory has a Torch Teledyne Tekmar analyser.

Organic analysis – Brno

The laboratory analyses oil, gas, light hydrocarbons and organic matter in sediments, rocks and soils. The results of the analyses are intended for environmental risk assessment, geological exploration and control of oil and gas production, geochemical mapping documentation. Environmentally oriented projects use analyses of selected pollutants indicative of specific types of pollution (e.g. PAHs, PCBs). For oil and gas exploration, analyses of hydrocarbon source potential, thermal maturity of source rocks, molecular fossils for correlation of oil and source rocks. The chemical and isotopic composition of methane, higher hydrocarbons and carbon dioxide are measured to assess the tightness of underground gas reservoirs and to monitor uncontrolled formation methane output. In addition to exploration parameters, lacustrine and marine facies indicators based on molecular analyses are used for basic geological mapping.

The laboratory provides services mainly to internal staff, cooperation can be arranged with scientific and pedagogical departments or analyses can be carried out in the form of a commercial contract.

Equipment

The laboratory has a range of gas chromatographs that are set up and configured to efficiently enable the analysis of given groups of chemical compounds.

For hydrocarbon analysis:

  • GC/MSD system AT 6890/5973N (Agilent Technologies)
  • AT 6890 gas chromatograph (Agilent Technologies)

For gas analysis:

  • 7890A gas chromatographs (Agilent Technologies)
  • HP 5890 gas chromatographs (Agilent Technologies)

For analysis of semi-volatile and volatile organic compounds:

  • ThermoEuroglas 1200 (Thermo Euroglas)
  • HP 5890 gas chromatograph (Agilent Technologies)
  • AT 6890 gas chromatograph (Agilent Technologies)

The following are available for supporting laboratory work:

  • microscope photometer Leitz MPV-2, the microscope allows the analysis of the nature of organic matter in transmitted, reflected and fluorescent light, measurement of the reflectivity of vitrinite in polarized and non-polarized light
  • liquid chromatograph AT 1100 (Agilent Technologies) with FLD and DAD detection, the instrument is used for the analysis of selected compounds of extractable fraction
  • ELTRA 1000CS elemental analyser (ELTRA). The instrument determines the carbon and sulfur content of solid and liquid samples by direct determination ofCO2 released from samples by combustion in oxygen (total carbon, TC) or by acid digestion (mineral carbon determination, TIC). The organic carbon content (TOC) is determined directly from the carbonate-free sample by decomposition in acid. Simultaneously, the total sulphur content (TS) can be determined by determining the sulphur oxides released from the sample by combustion in an oxygen atmosphere
  • Retsch jaw crusher
  • Retsch ball mill
  • IKA mill equipment
  • TurboVap analytical fraction concentrator (Zymark)

Range of services

  • determination of organic substances in rocks, sediments and soils
  • analysis of selected pollutants indicative of specific types of pollution (PAHs, PCBs)
  • analysis of hydrocarbon source potential
  • analysis of thermal maturity of source rocks
  • analysis of molecular fossils to correlate petroleum and source rocks
  • measurement of chemical and isotopic composition of methane, higher hydrocarbons and CO2
