Real time online monitoring of time-of-flight mass spectrometer

VOCsReal time online monitoring of time-of-flight mass spectrometer

UVP-TOF MS 2000typeReal time online monitoring of time-of-flight mass spectrometerBreaking through traditionGC-MSDue to the limitations of using capillary chromatography separation technology, photon ionization and its corresponding composite technology are adopted to achieve real-time and full spectrum ionization of the measured gas sample by exciting the outer valence electrons of organic molecules or inorganic gases. The sample does not require pre separation and is suitable for real-time online monitoring of pollutants in ambient air, hazardous chemicals in public security sites, and toxic and harmful substances in water bodies. As a convenient analysis tool, it has excellent sensitivity and measurement accuracy. The instrument can be configured with different sampling devices to meet various daily testing needs.
