Orbitrap Exploris GC S MS Pesticides & POPs

Precision and confidence for pesticide analysis

Obtain reliable pesticide results across complex matrices with a system designed for high throughput analysis. To help enable laboratories meet reporting requirements, the Thermo Scientific Orbitrap Exploris GC S Mass Spectrometer provides precise quantitation and consistent detection at low concentration levels.

For reproducible results across a broad range of pesticide compounds and sample types—supporting both current monitoring needs and evolving analytical requirements, the system combines high-resolution accurate-mass (HRAM) performance with a wide linear dynamic range and ultimate sensitivity.

Chromeleon software view of spinach matrix-matched calibration curve of Atrazine (0.5–200 µg/kg, triplicate injections), including extracted quantifier and qualifier ions at 0.5 µg/kg. Data were acquired using 60,000 mass resolving power proving good mass accuracy and selectivity in matrix.
