The Extrel MAX-HM series quadrupole mass spectrometers from Henniker Scientific are now available with extended mass range options to 16,000 amu
Each instrument in the range features the MAX-HM quadrupole mass filter assembly, a precision machined 9.5mm or 19mm rod set with improved RF-only pre- and post-filter stages, stabilising rods and high power RF generators.
In combination these claim to deliver transmission, resolution and abundance sensitivity characteristics at high masses.
They are available as a fully UHV compatible bolt-on instrument or with application matched single or compound molecular beam inlet pressure reduction stages, addressing a range of atomic and molecular studies, including nano-cluster deposition, analysis of bio-molecules, plasma polymerisation and SIMS/SNMS of polymeric materials.
The range covers discreet upper mass limits of 500, 1000, 2000, 4000 and 16,000amu, with frequency specific and interchangeable RF generators that also allow a single instrument to operate over multiple mass ranges without the need for re-tuning.
