Lieferung und Installation eines Analysensystems für die Kopplung von Gaschromatographie-Tandem-Massenspektrometrie

TENDER DESCRIPTION

A new gas chromatography system with a mass spectrometric detector (triple quadrupole) and atmospheric pressure ionization is to be procured at the Federal Institute of Hydrology (BfG). The decisive factor for the measuring system to be procured is the use of atmospheric pressure ionization (APCI), as this allows a soft ionization. The BfG must provide analytical solutions for numerous new pollutants, as these substances are regulated or will prospectively be regulated by the Water Framework Directive, the Surface Waters Ordinance, or developments of HABAB and GÜBAK. The analysis system to be procured is intended to close this gap, since atmospheric pressure ionization primarily generates molecular ions, resulting in significantly less fragmentation of the substances to be analyzed. This allows fragment-sensitive analytes, such as pyrethroids and multiply halogenated hydrocarbons, to be detected and quantitatively determined. Due to the lower fragmentation, the determination of other substances can also benefit because the analytical determination becomes significantly more reliable due to the larger precursor masses. Thus, for certain substances, significantly better measurement…
