TKN Analyzer

Manufacturer: BÜCHI Labortechnik AG
Model: Destillationseinheit „KjelFlex K-360" und IR-Aufschlusssystem "SpeedDigester K-436 Standard"
Facility: Institut für Abfall- und Kreislaufwirtschaft

The determination of organically bounded nitrogen (called TKN), is realized by a digestion and steam distillation with addition of sulfuric acid, sodium hydroxide and suitable catalysts.

Ion Chromatography

Manufacturer: Metrohm GmbH
Model: 709, 732, 733, 750, 882 Compcat IC plus
Facility: Institut für Abfall- und Kreislaufwirtschaft

Ion chromatography allows the determination of anions (e.g. chloride, sulfate, nitrate, nitrite and phosphate), cations as well as organic acids from liquid sample materials.

ICP-Optical Emission Spectroscopy

Manufacturer: Perkin Elmer
Model: ICP-OES "Optima 8000"
Facility: Institut für Abfall- und Kreislaufwirtschaft

Optical emission spectrometry with inductively coupled plasma (ICP-OES), wavelength spectrum: 165-190 nm with resolution of < 0.009 nm @ 200 nm.

Mikrowelle / Microwave

Manufacturer: CEM GmbH
Model: MARS 6
Facility: Institut für Abfall- und Kreislaufwirtschaft

Sieve Shaker

Manufacturer: Haver & Boecker
Model: Haver EML digital plus
Facility: Institut für Abfall- und Kreislaufwirtschaft

At the institute several sieve stacks are used to analyze the distribution of particle sizes of solids.

Fluidized bed pilot plant

Manufacturer: TU Dresden / ThyssenKrupp AG
Model: VERENA
Facility: Institut für Abfall- und Kreislaufwirtschaft

Thermal behavior of refused-derived fuel in stationary fluidized bed combustion. The integrated and complex analysis technique allows the online analysis of various parameters in the flue gas.

Overhead Shaker

Manufacturer: Heidolph Instruments GmbH
Model: REAX 20
Facility: Institut für Abfall- und Kreislaufwirtschaft

The overhead shaker is used to perform elution of solid samples. Referring to the elution process eluate and the residues of the elution process can be analyzed and balanced.

Gas Chromatograph (GC)

Manufacturer: HewlettPackard
Model: HP Agilent 6890
Facility: Institut für Abfall- und Kreislaufwirtschaft

By using gas chromatography at the institute the chromatograph can be coupled with a mass spectrometry for the analysis of polycyclic aromatic hydrocarbons and phenols.

Calorimeter

Manufacturer: IKA®-Werke GmbH & Co. KG
Model: Calorimeter C7000
Facility: Institut für Abfall- und Kreislaufwirtschaft

In addition to the possible digestion of samples for subsequent analysis by using ion chromatography the calorimeter is also used to determine sample-specific energy contents.

Drum sieve

Manufacturer: Max Boll GmbH & CO. KG
Model: Siebmeister
Facility: Institut für Abfall- und Kreislaufwirtschaft

By using a drum sieve larger amounts of solid samples can be classified in various grain sizes.
