  • MS-200 Portable time-of-flight mass spectrometer

    The MS-200 portable time-of-flight mass spectrometer is used to quickly detect VOCs in gaseous samples on site. It samples directly through a double-membrane sampling system without the need to separate and preconcentrate the sample. The instrument uses polycyclic time-of-flight mass spectrometry analysis technology to effectively improve the sensitivity of the instrument. Using the classic EI ion source, it can be seamlessly connected to the NIST mass spectrometry database certified by the laboratory today. Combined with the automatic mixture analysis software that comes with the instrument, it can analyze a variety of gas components in the concentration range from ppb to percentage (%). Rapid qualitative and quantitative analysis. Built-in battery drive can maintain long-term high-frequency operation (>6 hours), realizing rapid monitoring from the laboratory to the field.
