All green colored elements within the periodic table can be analyzed as main-, minor- and trace-components.

The analytic is possible from almost any solid or liquid matrix. For the handling of smallest sample quantities ultra-micro-weighing-scales with a resolution of 0.1 μg (micrograms) are available.

We subdivide our analytical services into the determination of metals, the determination of non-metals, the determination of anions and cations as well as other methods and parameters.

 

Determination of metals

About 80% of all chemical elements belong to the metals. Thus the metal-analytic forms a main area of our analytical work. The spectrum of elements that we can analyze contains about 70 elements and ranges from lithium to uranium. For the detection the following atom spectroscopic methods are available among others.

 

- ICP‐AES (Inductively Coupled Plasma ‐ Atomic Emission Spectroscopy)

- ICP‐MS (Inductively Coupled Plasma ‐ Mass Spectrometry)

- AAS (Atomic Absorption Spectrometry)

 

For the digestion of the samples to be analyzed, the below listed methods and systems are available. They are routinely used to analyze metals and some non-metals.

 

- Pressure digestion within quartz-, PTFE‐ und PFA‐vessels

- High pressure microwave digestion

- High pressure digestion within quartz vessels

- Digestion within sealed glass tubes

- Fusion

Determination of non-metals

The analysis of non-metals is an essential work area in our laboratory. It includes the detection of the elements hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur as well as the halogens. Depending on the requirements, different methods are applied for the determination of each element.

 

Hydrogen [ H ]

- Infrared spectroscopic detection after combustion to H2O

- Thermal conductivity detection after carrier gas hot extraction

Carbon [ C ]

- Conductometric detection after combustion and CO2 absorption

- Infrared spectroscopic detection after combustion to CO2

- Carbonate-C by conductometric detection after acid extraction and CO2 absorption

Nitrogen [ N ]

- Volumetric detection according to Dumas combustion method

- Thermal conductivity detection after carrier gas hot extraction

- Chemiluminescence detection after combustion

Oxygen [ O ]

- Conductometric CO2 detection after pyrolysis (according to Unterzaucher)

- CO detection by infrared absorption after vacuum hot extraction

- Combination of the above mentioned procedures

- CO / CO2 detection by infrared absorption after carrier gas hot extraction

Phosphorus [ P ]

- Spectroscopic detection after digestion by ICP-AES

Sulfur [ S ]

Spectroscopic detection after digestion by ICP-AES

- Titrimetric, microcoulometric, ion chromatographic or spectroscopic detection by ICP-AES after combustion

Halogens [ F - Cl - Br - I ]

- Fluorine, chlorine, bromine and iodine determination after combustion by titration, microcoulometry or ion chromatography

- Determination of fluorine after combustion by ion sensitive electrode

- Spectroscopic determination of iodine after combustion by ICP-AES

Determination of anions and cations

With the ion chromatography, ions of different charge can be separated from each other.. The anions and cations listed within the following lines belong to the most frequently analyzed ions.

 

Anions: fluoride, chloride, bromide, iodide, acetate, nitrate, phosphate and sulfate

Cations: ammonium

Other methods and parameters

In order to be able to provide you solutions for complex tasks, we work together with research and control laboratories from many different industrial branches. This gives us the opportunity, to offer you analyses by numerous methods and techniques.

In the following lines, you can find a selection of the available analyses / methods. Further methods from various analytical areas can be offered on request.

 

Absorption Spectroscopy (UV / VIS)

With this method, bonds in molecules can be analyzed. For this purpose, electrons are excited with electromagnetic waves in the range of ultraviolet and visible light.

Liquid Chromatography (LC / HPLC)

The technique allows a separation of individual liquid or dissolved components. For the qualitative/quantitative determination of the individual constituents, RI-, UV-, ELSD-detectors or a coupled mass spectrometer ca be used.

Gas Chromatography (GC)

The method is used to separate individual gaseous or vaporizable components. With a WL-detector or a coupled mass spectrometer, the contained components can then be determined qualitatively/quantitatively.

Infrared Spectroscopy (IR)

This technique analyses the interaction of infrared radiation with a sample. Based on reference spectra, contained compounds can be identified.

Nuclear Magnetic Resonance Spectroscopy (NMR)

The method can be used to analyze the intrinsic angular momentum (spin) of individual atomic nuclei and the interaction with their environment. 1H, 13C, 19F, 29Si and 31P are the nuclei that are most frequently measured by us.

Mass Spectrometry (MS)

With this method, the mass and the number of individual atoms or chemical compounds can be measured. In combination with liquid chromatography or gas chromatography, the method is used for instance, for the structure elucidation of different compounds.

X-Ray Diffraction (XRD)

This technique uses X-rays to determine crystal structures or to identify crystalline substances and bonding forms.

X-Ray Fluorescence (XRF)

This method detects the element-specific fluorescence radiation. In this way, the composition of a sample can be qualitatively and quantitatively analyzed.

Specific Rotation Angle

With this method, optically active substances can be detected and their purities can be measured.
