Area of organic investigations:

Infrared Spectroscopy FT-IR

Ph. Eur. 10, 2.2.24 – Infrared spectroscopy [accredited method: PL-19422-01]

Infrarotspektroskopie_Messung am Diamant ATR
Infrared spectroscopy: Measurement on the diamond ATR

The best known and most widely used method for the analysis of organic compounds. After excitation with an IR source, each functional group in a molecule absorbs energy at distinguished frequencies. The spectra obtained are additive, from summation of individual components. Therefore, single components under 1% of the total cannot be detected with certainty.

A typical relative measurement uncertainty for quantitative analyses is ±10%.

Gas Chromatography coupled with Mass Spectrometry GC-MS

Injector of a gas chromatograph

Ph.Eur. 10,2.2.28 - Gas Chromatography [accredited method: PL-19422-01]

This is the most sensitive method to analyze single components in complex mixtures. But only organic substances which can be vaporized without decomposition can be analyzed.

Organic compounds generate so called mass spectra. To identify unknown compounds the mass spectra will be compared with the NIST library in a current issue. This comprehensive library is the world’s most widely used mass spectral reference library with more than 240.000 entries.

A typical relative measurement uncertainty is ±10%.

High performance liquid Chromatography with UV Detector HPLC-UV

Flüssigchromatographie mit Diodenarray-Detektor und Lichtstreudetektor
Liquid chromatography with diode array detector and light scattering detector

Ph. Eur. 10, 2.2.29

HPLC is a chromatographic method in which larger molecules in solution can be separated. The high separating capacity of the chromatographic system is used to determine single compounds in complex mixtures. The high linearity provided by the UV detector for UV active components makes it suitable for quantitative work.

A typical relative measurement uncertainty is ±10%.

Ultra Performance Liquid Chromatography with High-Resolution Mass Spectrometry UPLC-HR-MS

Flüssigchromatographie mit Time-of-flight Massenspektrometer
UPLC with time-of-flight mass spectrometer

UPLC-HR-MS is a combination of HPLC and high resolution mass measurements. The use of special columns guarantees highest separation performance. The system is equipped with a Time-of-Flight Mass Spectrometer (TOF-MS) which provides a powerful combination of high resolution mass measurement with high sensitivity. It allows target quantitative analyses and structural elucidation and semi quantification for a wide range of analytes at low concentrations with appropriate standards.

Area of inorganic investigations:

Ion Chromatography IC

Sample preparation

The Ion Chromatography is the method of choice to detect inorganic ions sensitively. After separation single ions are detected due to their conductivity.

A typical relative measurement uncertainty is ±10%.

Inductive coupled plasma mass spectrometry ICP-MS

ICP-MS Plasma Kammer
Plasma chamber of the ICP-MS

ICP-MS is one of the most sensitive methods in inorganic trace analysis. Qualitative as well as quantitative analysis of almost all metals and metalloids in solution can be carried out at the same time. For quantification, selected elements are measured against a certified standard. For survey measurements a semi-quantitative program is used.

A typical relative measurement uncertainty is ±10%

Scanning Electron Microscopy with Energy Dispersive X-Ray according to DIN ISO 22309:2015-11 SEM-EDS

Specimen chamber of the scanning electron microscope

[accredited method: PL-19422-01]

Microbeam analysis – Quantitative analysis using energy-dispersive spectrometry (EDS) for elements with an atomic number of 11 (Na) or above. Good results will be obtained for mass fractions down to 1%. SEM-EDS is the standard method for surface and particle analysis. Single particles can be inspected and identified on the basis of the emitted X-Ray spectra.

A typical relative measurement uncertainty for quantitative analyses is ±10%.
