Transportable mass spectrometer
This compact, robustly designed, transportable Mass Spectrometer instrument incorporates all the latest Quadrupole and vacuum pumping technology housed in a robust case weighing less than 23kg. Its unique design allows the user to purchase one instrument model and select and connect any one of a number of sample interface systems to match the application. The powerful analytical software allows data to be quickly collected and either displayed as
a full mass spectra (showing all gas species present within a process) or quickly configured to measure specific gas components of interest and data log in real time. Both absolute, quantative (%, ppm) data as well as qualitative data may be measured with this instrument.
