Thermo Scientific Orbitrap Exploris EFOX Mass Detector

The Thermo Scientific™ Orbitrap Exploris™ EFOX Mass Detector is an Orbitrap-based mass detector designed for accurate and reliable trace contaminant analysis in environmental and food safety applications. This high-resolution mass spectrometry system enables comprehensive screening, quantification, and sample profiling within a single analysis while supporting efficient laboratory workflows and regulatory compliance.

The instrument combines high sensitivity, selectivity, and robust design with simplified workflows for both routine and advanced applications. Full-scan acquisition together with in-source fragmentation eliminates the need for time-consuming MS/MS method optimization. Integration with Thermo Scientific™ Chromeleon™ software ensures efficient data processing and management.
