EPIC: System for UHV Analysis of Neutrals, Radicals and Ions from Hiden Analytical

The Hiden EPIC and IDP are designed with the features of high performance RGAs and additionally provided with negative ion capability and pole bias mid-axis potential, thereby making them exceptional research grade mass spectrometers.

Key Features

The main features of the EPIC are given below:

Mass range options to 2500amu, 6 or 9mm pole diameter options

Improved long-term stability with less than ±0.5% height variation over 24h

Improved sensitivity for high mass transmission and automatic mass scale alignment

Pulse ion counter for continuous 1: 107 c/s decade dynamic range

Ion source control for soft ionisation and appearance potential mass spectrometry

Ion energy distribution by mid-axis potential scanning ±100 V, 1000eV option

Wide dynamic range - 5x1010 c/s with Faraday option

Improved contamination resistance via the RF-only pre-filter stage

Temperature reading integrated into data displays for thermal desorption applications

Signal gating 100ns resolution for energy and mass distributions vs time or TOF studies

MASsoft control via RS232, USB or Ethernet LAN

Upgradeable to plasma / SIMS specification

Integral UHV compatible shroud, liquid nitrogen cooled shroud option

Applications

The EPIC is used in the following areas:

Catalysis

Surface science
