Quadrupole Mass Filters

Extrel’s Quadrupole Mass Filters have long been known for their high performance, innovative design and rugged construction. To provide a wide selection of mass ranges and performance options, Extrel’s quadrupoles are manufactured in three (3) different rod sizes, 19mm, 9.5mm and 6mm. From Helium and Deuterium separation, to Cluster and Biomolecule deposition and analysis, Extrel’s quadrupole mass filters have been the first choice for researchers since 1964.

Extrel’s standard quadrupoles are equipped with pre and post filters to provide the highest possible ion transmission, thus offering the best resolution, sensitivity and abundance sensitivity. The standard quadrupole configuration also includes housing and entrance and exit lenses. For those applications that require additional pumping around the quadrupole, we offer vented housings as well as systems without housings.

For additional specifications and benefits of the Extrel Quadrupole Mass Filters, please reference the listed Product and Application Notes or contact your local Sales Representative.
