Chromatography & Electrophoresis

As the central laboratory for separation sciences of the Max-Planck-Institut für Kohlenforschung the Department of Chromatography & Electrophoresis offers an extensive range of analytical methods. We apply instrumental chromatographic and electrophoretic separations as well as hyphenated techniques.

In qualitative analyses we clarify the presence of specific components (i.e. postulated products in a reaction mixture). Over and above that we determine the concentration of requested components in quantitative analyses.

Atmospheric-pressure Plasmas

Atmospheric-pressure Plasmas

The plasma state of matter is defined as a gas wherein a certain portion of particles are ionized. Plasmas can be classified by temperature in thermal and non-thermal plasmas (often referred to as “cold plasmas”). The latter are characterized by a significant disparity of the electron and the ion temperature. Non-thermal plasmas are i.e. used for surface modification, cleaning or coating. We construct non-thermal plasma sources for applications in analytical chemistry.

Instrumental Developments

Our department is engaged in service analytics to support the preparatory chemical research groups in our institute. Therefore, application development as well as instrumental developments in the field of analytical chemistry is performed in close collaboration with our precision engineering workshop.

Gas Chromatography

Gas Chromatography

For the gas chromatography (GC) there is a great variety of different methods for common separations of chemical compounds with a boiling point ≤ 400 °C at our disposal (i.e. polar, apolar or chiral stationary phases). We provide:

  • High Temperature GC
  • Information about constitution, conformation, exact bond lengths and angles as well as the three-dimensional packing in the solid state.
  • Low Temperature GC
  • GC x GC
  • GC – MS
Liquid Chromatography & Electrophoresis

Liquid Chromatography & Electrophoresis

In liquid chromatography (LC) soluble compounds are analysed in a liquid phase. Doing so we carry out predominantly reversed phase and chiral LC separations. The preparatory LC instruments allow the purification of chemical substances in a typical mass range of 1 mg to 10 g. The purified products are analysed by GC, IR, MS, NMR, XPS or are used as educts for chemical synthesis. We provide:

  • Ion Chromatography (IC)
  • Size Exclusion Chromatography (GPC / SEC)
  • (Chiral) Supercritical Fluid Chromatography (SFC)
  • Hyphenated Techniques (HPLC-MS)
  • Gel Electrophoresis (GE)
  • Capillary Electrophoresis (CE)
  • Micellar Electrokinetic Chromatography (MEKC)
