Hiden launches 3FD mass spectrometer for fast, direct digital signal detection

Hiden Analytical Ltd of Warrington, UK says that, with the new 3FD model, its 3F-series of quadruple mass spectrometers now features direct digital signal detection for its fastest response and most sensitive detection levels, addressing research needs in the UHV/XHV vacuum regime through to specialized fast-event gaseous studies at pressures to atmosphere and beyond.

The system integrates triple-stage mass filter technology with digital data acquisition by direct positive ion counting (pulse counting) to combine a continuous detection range of seven full decades with a detection rate from just 1 ion per second and abundance sensitivity measurements to the parts per billion regime. The integral data accumulation mode enables operation with time-functioned data acquisition for the suppression of fundamental ion statistical noise. Vacuum partial pressures to 5x10-15 mbar are detectable.

Ionization source options are available for conventional residual gas analysis, for surface desorption studies, and for molecular/laser beam measurements. Single-stage and multiple-stage pressure reduction systems are available for operation at higher pressures beyond the UHV range. Requirements for the measurement of externally generated positive ions and for the measurement of both positive and negative ions are addressed by the alternative EP/EQ series. A custom design service is available for specialized applications.
