Analytical Tools

FTIR-Raman

FTIR-Raman setup with a Nd:YAG-Laser (1064nm) for standard measurements and measurements in the step scan mode (SST) in connection with a chopper and lock-in amplifier for in-situ experiments. See also FTIR-Raman

TOC Analyser

TOC &TIC Total Organic Carbon & Total Inorganic Carbon: Analyses the total carbon content of inorganic and organic compounds or mixtures (solid or liquid) by combustion in O2 atmosphere at 850°C (liquid) and 950°C (solid)

Timon Käser

WDXRF

Wavelength-dispersive x-ray fluorescence (WDXRF) is used for elemental analysis of solids and liquids. In contrary to ICP-MS or AAS it isn’t necessary to dissolve your sample to measure the elemental content. Our S4 Explorer can be used to detect almost all elements of the periodic system from sodium to uranium in the concentration range from ppm up to 100 %. There is also the option to measure carbon, oxygen and fluoride, but with less accuracy through their low-energy radiation.

Calorimeter

The calorimeter C1 is used for the gross calorific c value determination of solid and liquid substances.

It may not be used for the testing explosive samples. The gross calorific c value is determined according to an isoperibolic measurement procedure at 22°C (optional 30°C). The combustion of the sample takes place in a closed vessel with oxygen excess. The temperature rise of the static jacket filled with water will be measured. The sample amount is dependent on the combustibility of the substance. The temperature increase during the combustion has to be between 1 K and 10 K (40 000J). For most samples it is necessary to use about 0.5 g to 1 g per measurement.

TG FTIR

Simultaneous Thermogravimetric Analyser (Netzsch STA 409) coupled with an Infrared spectrometer (Bruker Tensor 27) for the analysis of evolved products.

Transient experiments can be conducted with a pulse device. See alsoTG FTIR

GC

HP 6890 Series, with two-column switching system TCD and FID detectors.
The GC is used for analyzing hydrocarbons, hydrogen, carbon monoxide, carbon dioxide, nitrogen, oxygen and methane.
FID (Flame Ionisation Detector)
TCD (Thermal Conductivity Detector)

CHNS elemental analyzer

CNS elemental analysis (Vario EL cube)
CNS elemental analysis (Vario EL cube)
Elemental carbon, nitrogen and sulfur can be quantified with the Vario EL cube. The device allows the analysis of either liquid sample or solid sample from mg to g range. Analysis is fully automatic with an integrated carousel which may receive 80 samples. The sample is injected into a first furnace operating at 1200 °C where catalytic combustion occurs. A second furnace (850 °C) is used for reduction of the combustion gases. A thermal conductivity detector (TCD) is used for N2 and CO2 detection below. An IR photometer detector allows the detection of SO2.

HP DSC

Sensys DSC manufactured by SETARAM with Calvet-style sensor. High-pressure, high-temperature isochoric measurements are performed up to 500 bar and 600°C using crucibles made of Incoloy® with an inner volume of 130 µL.

GPC

Gel Permeation Chromatography (GPC)
GPC is a chromatographic method for the determination of molecular weight distributions of polymers and oligomers. The macromolecules are separated on a column according to their volume and their retention time is determined. The molecular weight corresponding to a certain retention time can be determined using polymer standards with known molecular weight. For our biomass related research dimethylsulfoxide (DMSO) is used as eluent and a UV detector for detection of the macromolecule fractions
