By minimizing solvent use and waste production, the Axcend Focus LC not only reduces operational costs but also aligns with green analytical chemistry principles, making it an environmentally responsible choice for laboratories

Hear how Eurofins SOFIA GmbH successfully implemented the TSQ 9610 GC-MS/MS into their workflow for trac contaminant analysis and increased higher sample throughput using the combination of instrumentations and software.

Utilizing GC-MS/MS to quantify low levels of PBDEs in matrix samples. Including an assessment of linearity and instrument detection limits (IDLs) for all compounds as well as an extended robustness study over n=100 injections of matrix samples to assess the reproducibility of the detection of trace levels of PDBEs.

In this study, the suitability of the TSQ 9610 triple quadrupole GC-MS/MS system was assessed for the analysis of more than 200 pesticides in black tea at trace concentrations supplemented with SPE cleanup. The linearity, accuracy, precision, limit of quantitation, and injection reproducibility of 20 selected analytes representative of the different pesticide classes in black tea matrix are demonstrated.

The benefits of the Thermo Scientific™ Orbitrap Exploris™ GC mass spectrometer system for the analysis of trace level contaminants, such as pesticides, polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), and brominated flame retardants (BFRs) are showcased.
