Laboratories

Overview of the main laboratories

The laboratory of Environmental Chemistry and Soil Analysis is available to both undergraduate and graduate students to carry out thesis work and is also used for lectures on certain subjects (e.g. Environmental Chemistry Lab). Labs are equipped with Genesys 10 absorption spectrophotometer, Infinite M200 Pro microplate absorption and fluorescent spectrophotometer, Dionex ICS 5000+ combined liquid and ion chromatograph, Hewlett Packard 5890 Series II gas chromatograph, AMA 254 single-purpose atomic absorption spectrophotometer mercury analyzer, Perkin Elmer 306 atomic absorption spectrophotometer, TOC/TN analyzer Formacs and EA 1108 elementary CHN analyzer. Lasb allow processing of soil or biomass samples, i.e.  weighing, agitation, filtration, titration, incubation, sonication, extraction, drying, lyophilization, drying in a nitrogen stream or rotary vacuum evaporator, microwave decomposition and decomposition in heating mantles, mineralization of soil and plant samples in a mineralization block (MB 64 RTK) or homogenization and grinding of soils, plant biomasses.

The laboratory for Air Quality Research is equipped with state-of-the-art instruments allowing field and lab-based chemical and physical analysis of atmospheric compounds. For gaseous species HORIBA 360 series units are available. Aerosol characteristics are determined using SMPS 3936 LN 25 and APS 3321 spectrometers, DustTrak laser photometers, an FH 62 I-R beta attenuation monitor, and low and high volume single stage and cascade impactors. The absorbance/reflectance can be measured by a standard smoke stain reflectometer (M43D). Passive dosimetry (OGAVA, WILLEMS) is also used. An air-conditioned mobile container can be equipped with the above-mentioned instruments and used together with a meteorological station in the field. A small wind tunnel with a total volume, closed air circulation and a resuspension chamber is used in deposition and resuspension laboratory experiments. Chemical analysis of samples is performed by ICP-MS, AAS, AMA and other techniques

HS zima

The laboratory at the Velký Pálenec field station near Blatná is equipped with an ion chromatograph to quantify cations and anions in water sample. There is also an alkalinity titrator, Turner spectrophotometer and fluorometer for chl-a measurements, Hydrolab water quality probe with datalogger used for measuring depth, temperature, dissolved oxygen, pH and conductivity in the field, microscopes and many samplers for field work including a rubber boat. See www.blatna.cuni.cz.

GIS laboratory is focused on description of landscape dynamics over time and of various transportation processes in landscape, such as dynamics of succession vegetation in abandoned fields or post mining sites, transport of dust from coal mines or avalanche movement in mountain environment.

The Water Quality Laboratory carries out research in the field of drinking water treatment and surface water contamination (heavy metals, persistent organic pollutants). Experimental research on drinking water treatment is mainly focused on removing Al, natural organic matter and pesticides, as well as the efficiency of different destabilization and aggregation reagents. The laboratory is equipped with special instruments needed for technological tests (jar tests, water softening, Fe, Mn, Al removal). Advanced analytical equipment (GC-ECD/FID) of the Gas Chromatography Laboratory enables analysis of organic pollutants (pesticides, PAU, PCBs, etc.). Water treatment pilot-plant tests also take place at selected waterworks. Constructed pilot-plant installations simulate the technologies used at waterworks.

Limnology Laboratory and Microscope Room

The Limnology Laboratory is primarily used for processing “wet” biological material. These are live or fixed samples which require thorough washing and rinsing for processing. The laboratory is equipped with Olympus SZ51 and Arsenal STC 902 stereo microscopes for classifying and determining aquatic invertebrates, including literature for making such determinations. There are also samples prepared in the laboratory for analyzing subfossil organisms.

The Microscope Room is exclusively intended for working with dry and clean material. It is equipped with an Arsenal SZP 1102 ZOOM (45x) stereo microscope with a camera adapter and a Zeiss Jena Jenaval microscope (with 100x immersion lens) and built-in camera providing live images, which can be controlled from a PC.
