DLS-10

Ultra High Resolution Quadrupole Mass Spectrometer

  • Model: DLS-10
  • Manufacturer: Hiden Analytical

The Hiden DLS series systems are designed for applications in fusion where analysis of hydrogen isotopes and deuterated compounds are of interest. The DLS-10 mass spectrometer is for ultra-high resolution mass spectrometry of hydrogen isotopes, operating in the quadrupole stability zone H, to give mass separation of both deuterium within helium and helium within deuterium.

Features:

  • Fast access for Histogram, Trend Analysis and Analog peak displays.
  • Mixed mode scanning. Trend Analysis, Histogram and Analog peaks in a multi-window display for example.
  • Ion source control for soft ionisation and appearance potential mass spectrometry.
  • Simultaneous real time display of graphical and tabular trend analysis data.
  • Data acquisition from multiple systems via Ethernet.
  • Automatic mass scale alignment.
  • Integral mass spectral library with full editing facilities.
  • Data export facility to ASCII format and to all Windows® devices for printing/plotting.
  • Socket Interface for application control and dynamic data link with Windows® compliant applications.

Applications

  • Fusion research
  • Isotope studies
  • Synchrotron studies
  • Nanotechnology
  • Residual gas analysis
Category:

The DLS-10 quadrupole analyser is a precision assembled triple mass filter with unique, independently driven RF only secondary filter stages preceding and following the primary mass filter. A radially symmetric electron impact ioniser with twin oxide coated iridium filaments and a dual Faraday / single channel electron multiplier detector are included as standard.

Mass range is 1-10 AMU operating in the quadrupole stability zone H with FWHM =0.003 amu.

DLS-10 systems are directly controlled from a PC compatible computer via RS232, USB Ethernet link, providing simultaneous data acquisition from multiple systems. The RC interface unit is a 90 mm high (2U), 19 inch rack mounting unit. It is mains powered and includes power on and filament status indicators.

Windows®-MASsoft Professional PC software provides for fast data acquisition through either user configured acquisition files or pre-set modes selected by icon.

The Hiden DLS-10 system comprises:

  • RC control interface unit.
  • RF generator with preamplifier configured for operation in zone H.
  • Triple filter analyser with integral electron bombardment ion source, precision mass filter and dual Faraday/single channel electron multiplier detector.
  • Connecting cables.
  • Windows® MASsoft Professional PC software.

The system requires a PC for operation, not included in this item.
