Analytical GC & LC

In the Chromatography Lab whole oil analyzes are performed with special attention to saturated hydrocarbons, highly volatile organic compounds, and lipid fractions (e.g. fatty acids, alcohols, sterols).
Aqueous Chemistry

For quantification of organic (e.g. acetate, formate) and inorganic anions (e.g. chloride, sulfate) in aqueous samples ion exchange chromatography is used.

The quantification of the dissolved organic carbon (DOC) in aqueous samples and chromatogra…

HELGES – Helmholtz-Laboratory for the Geochemistry of the Earth Surface

In the HELGES Laboratory, sample preparation and measurements of cosmogenic nuclides (¹⁰Be, ²⁶Al) and stable isotopes of metals and metalloids (currently Li, Mg, Si, Fe, Sr, B) in geological and environmental sample materials, such as sediments, roc…
HELGES – Iridium Strip Heater

An iridium strip heater is a specialized heating device that uses iridium, which has a high melting point, corrosion resistance, and excellent electrical conductivity. At the HELGES laboratories, the Iridium strip heater is used to produce homogeneo…
HELGES – Mineral Sorter

The mineral sorter is suitable for separating minerals from sediment in which the minerals to be separated differ in brightness and color. After previous sieving, the dry sediment is sorted into light and dark parts up to a maximum grain size of 1 m…
HELGES – Neptune | Multicollector Inductively Coupled Plasma Mass Spectrometry (MC-ICP-MS)

The main application of the Neptune MC-ICP-MS mass spectrometer is the analysis of stable and radiogenic isotope ratios of elements purified from a wide range of geological materials, including rocks, soils, plants, waters, and more. We have establi…
HELGES – Sample Digestion System

Our laboratory is equipped with one of the latest sample digestion systems. The Multiwave can digest samples of all kinds - e.g. food, environmental, pharmaceutical and, of course, geological samples. The samples can be digested at up to 300°C and 2…
HELGES – Sample Preparation Laboratories

Samples of all kinds are pretreated in our sample preparation laboratories. Samples are usually first dried, sieved or separated into magnetic or non-magnetic components in a magnetic separator based on their magnetic properties. Separation based o…
