3F PIC / 1000 Series PIC

The quadrupole analyser is a precision assembled triple mass filter with unique, independently driven RF-only secondary filter stages preceding and following the primary mass filter.

A pulse ion counting single channel electron multiplier detector is included as standard. A Faraday detector option extends the dynamic range to 5×10¹⁰. Pulse ion counting detection provides seven decades continuous dynamic range and with the Faraday detector option, full analytical capability is extended to > 10 decades.

Mass range options are 50, 300 and 510 amu. The 50 amu system is used for optimum low mass resolution and abundance sensitivity.

The HAL/3F RC PIC mass spectrometer includes a UHV low profile electron impact ioniser with twin oxide coated iridium filaments as standard. System options available include cross beam sources and a range of analyser shrouds suited for molecular beam studies. The ioniser electron energy can be scanned and set for threshold ionisation and soft ionisation applications.

Features:

• Pulse Ion Counting detector for fast direct positive ion detection.
• ‘Low-profile‘ ion source. Desorbing surfaces may be positioned to within 8 mm of the ionisation region.
• Wide dynamic range. 7 decade continuous log scale, and up to 5 x 1010 with Faraday option.
• High sensitivity. Detection levels to 5 x 10^-15mbar.
• Fast data acquisition. Up to 650 measurements per second.
• Ion source control for soft ionisation and appearance potential mass spectrometry.
• Gating input for pulsed gas studies with 50 nanosecond gating resolution.
