Laboratory for Sediment and Soil Analysis (SEDILAB) HUN-REN Research Centre for Astronomy and Earth Sciences, Geographical Institute


SEDILAB as a whole is organised around this laboratory unit.

Soil physical measurements and rainfall simulator research were started in the first half of the 2000s in the LSSA. From the soil physical measurements, the determination of porosity, porosity content and bulk density are based on the method developed by Ferenc Vér. The density results from this method are controlled by pycnometer measurements. In addition to the soil physical measurements, hygroscopicity tests are also available.

This laboratory unit primarily provides instrumental analysis of liquid and solid phase soil organic matter but also performs spectroscopic analysis of other liquid, soil and plant samples, as well as solid phase geological and planetary meteorite samples.

SEDILAB's Liquid Chromatography Laboratory was established as a result of the NPKP project (NPKP_16-1-2016-0003) "Exploring the environmental risks of certain EDC residues in treated and untreated municipal wastewater in the Budapest urban area" ( These measurements also have a key role in the ongoing KFI projects (2020-1.1.2-PIACI-KFI-2021-00309).

The SSI Laboratory provides a broad spectrum of determination of the particle size distribution and characterization of unconsolidated sediments, soils, suspensions and colloidal systems.The Laboratory has instrumental capacities for particles sizing between 10 cm and 1 nm size range.

The SEDILAB Adsorbent Development and Adsorption Research Laboratory is a laboratory unit contributing to the development of cost-effective adsorbents for the purification of treated wastewater and irrigation water (freshwater bodies) from organic micro-pollutants, using the results of fundamental research.
