Hiden Analytical Europe GmbH

We are pleased to announce the opening of our new company Hiden Analytical Europe GmbH. The new company located in Düsseldorf Germany is responsible for sales and service of Hiden Analytical products in Germany and Austria.

Quadrupole probe analysers for UHV/XHV

The Hiden RGA series of quadrupole mass spectrometers for in-vacuum process analysis is further extended to include systems for applications from general vacuum monitoring through to specialised environmental and R&D applications.

New Compact HPR-20 Gas Analyser Family

Hiden Analytical introduce the new HPR-20 range of application-specific compact benchtop gas analysers for dynamic measurement of in-process gas composition. All systems feature precision quadrupole mass spectrometers with standard mass range options 200 and 300 amu, with mass range options from 20 to 1000 amu being available for specialised applications.

DEMS technique characterises fuel cell chemistry

Hiden Analytical announce a new agreement with The University of California, Berkley Laboratory, to produce their novel dual-layer differential electrochemical flow cell for operation with the Hiden HPR-40 DSA membrane inlet mass spectrometer. The combined differential electrochemical mass spectrometry technique (DEMS) is developed for real-time characterisation of electro-catalytic performance with special relevance to fuel cell chemistry, giving fast identification of gaseous and volatile product and intermediates generated during the electrochemical faradaic reactions directly at the electrode/electrolyte interface.

Hiden ExQ Gas Analysers for TGA/TA Analytics

The Hiden ExQ quantitative gas analyser is a new multi-featured and compact mass spectrometer system providing continuous on-line analysis of dynamic gas streams at pressures from sub-atmospheric up to 30 bar, the comprehensive range of process interface options enabling adaptation of the system for direct connection to the majority of standard TGA/TA instruments.

Microreactor/MS System for Thermal Process Characterisation

The Hiden CATLAB-PCS combined microreactor and mass spectrometer system is purpose designed for the characterisation and evaluation of catalysts, for temperature programmed desorption and reaction testing, and for general thermal studies. The modular benchtop system features an advanced fast-response low thermal mass 1000<sup>o</sup>C furnace, multistream gas flow control of up to eight integrated gas streams, together with the precision Hiden quadrupole gas analyser.

Diagnostic Tools for Atomic Layer Deposition

Hiden Analytical offers a range of mass spectrometer products of special significance to the process and post-process stages of atomic layer deposition(ALD) and evaluation.

Systems are available to monitor gaseous species through the pressure range from ultra-high vacuum through to the millibar regime, from in-process residual gas analysers through to the HPR-30ALD differentially pumped probes for the highest process pressures.

New Hiden Brochure Details MS Vacuum Process Monitors

Hiden Analytical release their new brochure featuring the full range of quadrupole mass spectrometers designed specifically for vacuum process monitoring. Systems cover the full pressure range from UHV(background species, leak detection) through to the millibar regime(process monitoring, control and protection).

Mass spectrometer operating mode enhances spectral purity

Analysis of gaseous species by quadrupole mass spectrometry involves ionisation of the molecular species most typically by the electron bombardment technique, the ionisation process creating fragmentation ions additionally to the parent ion. Spectral interpretation can then be compromised by spectral interference in some gaseous mixtures.

Hiden Analytical introduce the APSI(Appearance Potential Soft Ionisation) mode to their full range of gas analysis systems to enable reduction of the fragmentation ion effect for many species, resulting in enhanced spectral purity to simplify spectral interpretation. Each molecular species has a specific ionisation energy threshold at which the parent ion is formed, higher electron energy then generating fragmentation of the ion. The Hiden APSI mode enables the user to set discreet ion energies from as low as 4eV for each individual mass channel to selectively identify parent ions and to minimise generation of fragmentation ions.

Application examples include identification of deuterium in helium(both at m/z 4), ammonia in the presence of water vapour(suppression of the OH+ ion at m/z 17), part-per-million water levels in argon(suppression of argon isotope ion 36A++ at m/z 18). The 3D profile scan presentation displays selected multiple mass channels with peak intensity v. electron energy to rapidly establish the beneficial and individual energy levels for each selected mass channel.
