The Hiden HPR-60 system is specifically designed for analyses at process pressures from sub-atmospheric through to 10 bar.
Mass spectrometric analysis of the ionised and chemically unstable reactive species generated in flame and high-pressure plasma environments requires their rapid transit through vacuum to the mass spectrometer with minimal interaction.
Multiple ultra-high-vacuum (UHV) stages with independent turbomolecular vacuum pumping are separated by coned diaphragms - each with a central orifice - all precisely aligned to enable the unhindered transmission of the sampled beam through to the mass spectrometer probe for analysis.
The mass spectrometer is the Hiden EQP Mass/Energy analyser measuring mass and energy of both positive and negative ions, with the on-board electron bombardment ion source providing analysis of neutrals.
A mechanical beam chopper enhances detection levels for neutrals by modulating the beam, data acquisition then being gated to enable direct comparison of beam-on/beam off intensities for subtraction of background elements.
Systems provide detailed analysis of plasma and flame chemistry together with reaction kinetics and confirmation of gas-phase intermediate species.
A custom design service is available to assist with specific user interface requirements.
