GC-MSMS Agilent 7000B Triple QuadrupoleA (originál)GC-MS/MS Agilent 7000B Triple Quadrupole

Gas chromatography coupled to tandem mass spectrometry (triple quadrupole) equipped with electron impact ionization technique is employed for the analysis of pesticide residues in a wide range of foodstuffs (e.g. fruit, vegetable, tea, cereals). This instrumentation allows to measure more than 300 pesticide residues in less than 30 minutes at ultra-trace concentrations in one run. This system is also equipped with a JetClean function for self-cleaning ion source with hydrogen.

GC-MSMS Agilent 7000B Triple Quadrupole (originál)GC-MS/MS Agilent 7000B Triple Quadrupole

Gas chromatography coupled to tandem mass spectrometry (triple quadrupole) is particularly used for the analysis of environmental contaminants (e.g. polychlorinated biphenyls, flame retardants, organochlorine pesticides). Applications allow multi-detection analysis in a wide range of environmental (e.g. soil or atmosphere), food (e.g. meat, fat, fruit or vegetable) and biological (e.g. human breast milk or human blood serum) samples. This second triplequad system is also possible to operate in chemical ionization suitable particularly for the analysis of halogenated compounds and it is equipped with fully automated device for solid phase microextraction (CTC Pal) for the analysis of volatile compounds.

GC-MSMS Agilent 7000C Triple Quadrupole (originál)GC-MS/MS Agilent 7000C Triple Quadrupole

Gas chromatography coupled to tandem mass spectrometry (triple quadrupole) is an alternative technique to a system Agilent 7000B for the analysis of environmental contaminants (e.g. polychlorinated biphenyls, flame retardants, organochlorine pesticides). Applications allow multi-detection analysis in a wide range of environmental (e.g. soil or atmosphere), food (e.g. meat, fat, fruit or vegetable) and biological (e.g. human breast milk or human blood serum) samples. By Agilent 7000C system we can achieved lower limits of quantification for target analytes compared to the system Agilent 7000B. This system is also equipped with a JetClean function for self-cleaning ion source with hydrogen.

The last generation of gas chromatography coupled to tandem mass spectrometry (triple quadrupole) is employed for the analysis of pesticide residues in a wide range of foodstuffs (e.g. fruit, vegetable, tea, cereals) and environmental samples. This instrument allows to measure more than 300 pesticide pesticides in less than 30 minutes in one run. Its high-efficiency electron impact ion source produces at least 20 times as many ions as the previous generation, improving the efficiency of the entire workflow.
