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 chromato…
ElMiE-Lab - Elements and Minerals of the Earth Laboratory

The ElMiE Lab is a research-oriented facility and part of the Helmholtz center in Potsdam. The ElMiE - Lab offers the sample preparation and analyses of geological or environmental inorganic samples for element concentrations and mineralogy of inorg…
Geochemistry and Radio Isotope Laboratories

Microorganisms interact with their environment as they produce and and consume dissolved compounds that will therefore become depleted or enriched in their surrounding, mainly in the pore water. Analysis of dissolved compounds is therefore a prerequ…
HELGES – Clean Laboratory For Stable Metal(loid) Isotopes

Within HELGES we have a ISO 6 metal-free clean laboratory, dedicated entirely to blank-sensitive metal(loid) geochemistry. Numerous ISO 4 laminar flow hoods are available for the preparation of wide-ranging sample substrates for non-traditional stab…
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…
Ion Chromatography

Ion chromatography is used to analyze anions in aqueous solutions. This physical-chemical separation process is based on the distribution of the substance into a mobile fluid phase and a solid stationary phase. We analyze mostly chloride (Cl⁻), fluo…
Isotope Geochemistry Labs

The Isotope Geochemistry Labs are equipped with a clean room facility (including several low-blank chemistry laboratories (class 100), sample preparation and ion-exchange chromatography, a set up for isotope systems: Pb, U-Pb, Rb-Sr, Sm-Nd as well a…
