WARRINGTON, England, Aug. 10, 2011 — The HPR60-EQP from Hiden Analytical Ltd. is a fully integrated system configured for measuring atmospheric and near-atmospheric plasma and reactive processes in applications including analysis of atmospheric plasma jets, dielectric barrier discharges and flame chemistry. The system uses three stages of pressure reduction with orifice sampling at each interstage to provide fast transfer of reactive and neutral species directly to the integral EQP molecular beam-sampling mass spectrometer. The EQP system enables direct measurement of the mass and of the ion energy of positive and negative ions, and of neutral species with the integral electron bombardment ion source. Electronegative species may be identified and measured independently via the built-in electron attachment mode. Energy range is up to ±1000 eV, and molecular weights from 1 to 2500 atomic mass units are accommodated. A custom design service is offered, if required, to engineer a suitable system interface to adapt the sample extraction zone to the reaction region.
