All systems measure both positive and negative ions, with the integral electron bombardment ion source enabling neutrals and radicals analysis and featuring an advanced appearance potential scanning routine. Additionally the Electron Attachment Ionisation mode is developed specifically for studies of electro-negative species.

The new EQP-20 system is ultra-high sensitivity, ultra-high resolution and specifically developed for applications such as the analysis of hydrogen isotope plasmas. The EQP-20 can be operated in both the first and second quadrupole stability regions, Zone I and Zone H, allowing very high resolution in the mass range to 200 amu and ultra -high resolution in the range to 20 amu. Features include 0.026 amu mass separation and real time quantification of Deuterium and Helium to 10 parts per million levels in Zone H operation.

The 9 mm quadrupole diameter, EQP-9 is the high performance system of choice for high mass plasma analysis. With mass range options to 5000 amu, compound and cluster ion plasmas can be characterised.  Alternative mass ranges can be specified with an additional RF Power supply, giving the system further flexibility, suitable for a wide variety of plasma applications. The most cost effective of the series, the 6 mm diameter EQP-6, features Hiden’s triple filter quadrupole, for high sensitivity and stability measurements of plasma species.

EQP Series Mass range options are:

• EQP-6 – 300, 510 amu.
• EQP-9 – 50, 300, 510, 1000, 2500, 5000 amu.
• EQP-20 – 20/200 amu.

Energy range is 100 eV as standard, 1000 eV is optional.
