• FB 5.7-01 Infoblatt Probenanforderungen ( D+E)

• FB 5.8-01 Analysenauftrag

• The AAS device which is equipped with a flame-, graphite furnace- and hydride technology, is especially used for trace analysis to the lower ppm range. The element determination is based on the principle that the absorption intensities of the specific element lines are compared with those of a matrix-adapted calibration

• Spectrometer specifically used for the analysis of quicksilver in lowermost trace range to ppt.The element determination is based on the principle that the fluorescence intensities of the specific quicksilver lines are compared with those of the quicksilver-calibration. The quicksilver is separated via hydride technique of the matrix. Eventually it may be concentrated with amalgamation

• automatical fusion machine for the preparation of borate-melting tablets for subsequent X-ray fluorescence analysis of for example, slags, flue dusts, ores and minerals

• Ion chromatography is a seperation procedure based on the distribution of the components of a mixture of materials between a solid stationary phase (column) and a mobile phase (eluent) with subsequent detection (detector). At the IME this system is used for separation and determination of anions in solutions or dissolved substances. Common used methods are: 1. the anions fluoride, chloride, bromide, nitrate, phosphate and sulfate with the power detector from about 0.1 mg/ l and 2. The determination of sulfide and cyanide with the amperometric detector in im µg/l-area

• With this device thermo-gravimetric analysis (TGA) as well as (simultaneous) differential thermal analysis (DTA) can be performed. On the TGA the mass change is measured as a function of temperature while the substance is subjected to a controlled temperature program. On the DTA the temperature difference between a substance and a reference material is measured as a function of temperature while the substance is subjected to a controlled temperature program. The maximum working temperature of this device is at 1550 ° C. As a standard the following gases could be used: air, argon, oxygen, nitrogen and vacuum

• x-ray fluorescence device for the qualitative and quantitative analysis of metals, slags, ores, flue dusts, minerals and fluids. The elements of the periodic table can be analyzed with this device from sodium to uranium

• implementation of titrimetric analyzes such as acid-base titrations, redox titrations (and Karl Fischer titrations)

• The spark spectometer device is used fort the quick analysis of metals such as an online-analysis. The device is equipped for the analysis of the following bases:

• A spectrum analyzer for the simultaneous element analysis of casted samples equipped with a 75 cm Rowland circle, situated optics and radial plasma observation. The element determination is based on the principle that the emission intensities of the specific element lines are compared with those of calibration matrix-adapted

• The ICP device has an axial plasma observation. Due to the sensitive optics and the axial plasma observation better response level in the low ppm range can be obtained. The axial plasma observation provides an improvement in the response level by a factor of about 4 to 10 to radial plasma observation

• A Glowdischarge-spectrum analyzer for the analysis of metals as \"bulk\" analysis or for the analysis of coatings (thickness and composition of the coat). The device is equipped for the analysis of the following bases:
