Ultra High Resolution Quadrupole Mass Spectrometer

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 Helium and Deuterium.




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 =0.006 amu.



Triple Filter mass spectrometer operating in zone H


The combination of a 6 mm pole diameter micron precision mass filter, and the high frequency RF at low mass range is ideal for analysis of He and H isotopes.

The system is supplied with MASsoft Professional software.

This Windows 10 and Windows 11 compatible software allows control of the instrument via USB 2.0, RS232 or Ethernet. Provides comprehensive I/O for data output and for reading data from external devices for integration and display with mass spectrometer data.

The iRGA software is a new and intuitive application for routine vacuum monitoring. It is designed to be simple and automatic.

  • automatically provides partial pressure data for the common residual gas and vapours, including hydrogen, helium, water, nitrogen, oxygen, argon and a custom gas.
  • includes a new tablet view where the background colour changes depending on alarm condition
  • includes a trend view, scan, leak detection and maintenance modes
  • includes alarm function to send alerts to internal I/O, Wi-Fi and by email
