Isotopx at Goldschmidt 2014, Sacramento

May 16th, 2014


Here at Isotopx, we eagerly anticipate the conferences we attend, as it is an opportunity to interact with new and existing customers and discuss the latest developments in the company.

First on our conference schedule is Goldschmidt in Sacramento, California in June, where we will be continuing our tradition of supporting the geochemistry community by serving as a sponsor for what we regard as the leading conference in geochemistry. 

Isotopx will have a strong attendance at Goldschmidt, with experts on hand from both the TIMS and Noble Gas product lines who will be happy to discuss our most recent technical innovations.

Swing by our booth (#6) in the exhibition to find out about the latest developments at Isotopx, or why not contact us to arrange a meeting over lunch or a beer?

Damian Tootell (Noble Gas –

Jeremy Inglis (TIMS –


We look forward to seeing you.

Not attending Goldschmidt this year?  Look out for future posts about the other conferences we will be attending, including AGU and the International Conference on Isotopes 8

Isotopx to sponsor DINGUE 2013 in Florence

February 5th, 2013

DINGUE meeting logo

Isotopx have announced sponsorship of the DINGUE 2013 noble gas meeting to be held in Florence on the 23rd and 24th of August 2013. The DINGUE  meeting is loosely attached to Goldschmidt which starts on 25 August in Florence to allow geochemists to easily attend both meetings.

DINGUE is an important meeting for the noble gas community since it concentrates solely upon technical and scientific aspects of noble gas applications to terrestrial and extra terrestrial science. Its close association with Goldschmidt also ensures that attendance is usually excellent.

Isotopx will have a booth at DINGUE and will present within the scientific programme on the NGX instrument.  Details of the presentation will be available from this website immediately after the meeting has closed but we will be using the opportunity to make the noble gas community aware of some of the more technical details of the instrument and its performance.

NGX: A new Multi-Collector Noble Gas Mass Spectrometer from Isotopx

NGX: A new Multi-Collector Noble Gas Mass Spectrometer from Isotopx

Isotopx introduces the NGX Multi-collector noble gas mass spectrometer. The instrument uses the proven 27cm radius magnet used in the Phoenix Thermal Ionization Mass Spectrometer with a combination of Faraday and ion counting SEM detectors.

At less than half the volume of the VG5400, the comparative sensitivity is doubled. This is achieved by using an asymmetric arrangement of the ion optics whereby the image length is shortened but still allows the accurate measurement of resolved helium with increased sensitivity.

The design includes novel insulator materials within the ion source that have been specifically selected to reduce contributions to background signals at interfering masses.

We also describe the performance of the latest Faraday amplifier technology of high gain 1e12Ω amplifiers. In comparison to the more traditional 1e11Ω amplifiers, the theoretical signal/noise is improved by a factor of ~3. However, the signal decay or “tau response” times are not significantly compromised (5ppm of peak signal within 3 seconds). This has a favourable impact upon analysis times when peak-hopping.

This paper highlights efforts to improve instrumentation by increasing sensitivity and reducing background interferences which are factors currently limiting analytical precision in Noble Gas instrumentation, whilst showing enhanced Faraday amplification performance to minimise analysis times and improve accuracy.
