Electron Ionization Quadrupole Mass Spectrometer

Electron ionization quadrupole mass spectrometers are tools that analyze a sample by producing spectra based on the mass-to-charge ration of individual components. Many industries, including pharmaceutical and chemical, use this method for quality control and sample analysis. What makes the electron ionization quadrupole mass spectrometers different from other electron ionization mass spectrometers are the four rods in the chamber of the spectrometer. The four rods have different voltages and they are varied as the sample makes its way through. By watching what ions come out at which voltages, the sample can be identified. When deciding which electron ionization quadrupole mass spectrometer will work best for your needs, you need to keep several factors in mind. Does a single or triple filter, an open ion source or a crossbeam ion source, a digital or an analog detector better fit your needs? These questions, along with knowing how much sample is needed and the mass ranges it can detect, will help you pick the correct quadrupole mass spectrometer.
