The Extrel MAX-60 Series quadrupole mass
spectrometers from Henniker Scientific are designed
for precision mass analysis of low molecular weight
species whilst delivering exception transmission
characteristics.

Each instrument in the range features the MAX-60
quadrupole mass filter assembly, a precision machined
19mm quadrupole rod set with RF-only pre- and post-filter
stages, stabilizing rods and high power RF generators
that in combination deliver excellent transmission,
resolution and abundance sensitivity characteristics
at low masses.

Typical applications include geochronology isotope
ratio measurements and helium-deuterium gas purity
analysis, where the spectrometer’s resolution figure
of m/deltam=3000 is able to resolve adjacent mass
peaks separated by only a few hundredth’s of an
atomic mass unit.

The instruments are available as fully UHV compatible
bolt-on probes or with application matched pressure
reduction stages which address a wide range of atomic,
molecular and surface analysis studies.
