Hiden Analytical have introduced a family of quadrupole mass spectrometers designed specifically for UHV/XHV performance, evolved from their 3F series concept and incorporating their triple-stage mass filter technology for mass separation, ion transmission efficiency and contamination resistance. Pulse ion counting detection is common throughout this series, with a choice of positive-ion-only or combined positive and negative ion detection. Quadrupole mean energy scanning is featured for systems configured for analysis of externally generated ions. All systems feature the Windows MASsoft Pro multi-mode control program with multi-parameter scanning for optimisation of operating parameters for each individual mass channel. A choice of ionisation sources enables system optimisation for varied applications including molecular beam, laser ablation, thermal desorption and general neutral studies. All ion source parameters are software-controlled with modes for ion attachment, “soft” ionisation and appearance potential measurement.
