Functions & Applications

Crossed molecular beams method provides a means to study fundamental gas-phase reaction dynamics under single-collision conditions. In this universal approach, two atomic or molecular beams are crossed at 90°, and products that scatter from the intersection region are detected with a quadrupole mass spectrometer detector. The detector uses electron-impact ionization, which allows detection of a wide variety of products.
