Noble Gas NGX NGX static multi collector noble gas mass spectrometer

Description

The NGX is our static multi collector noble gas mass spectrometer designed to measure isotope ratios of any of the noble gases at high precision and accuracy. It uses conventional 1:1 ion optics with the very latest electronics to give simple fixed multi-collection coupled with high performance and sensitivity.     

NGX was developed as the culmination of over 40 years of experience in noble gas magnetic sector mass spectrometry. It uses two recently patented developments: a high-sensitivity, low-temperature cathode source and high dynamic range ATONA® Faraday amplifiers (learn more) combined with advancements in electronics and design to produce a truly outstanding instrument.

Developed in collaboration with noble gas users around the world, NGX can collect any of the noble gases. It retains the simplicity in operation of previous generation instruments but uses modern developments in design and manufacture to produce state of the art performance. We have delighted customers in a number of prestigious noble gas labs around the world.

Key Features

• Patented technology: High dynamic range, electronically calibrated ATONA^® Faraday amplifiers
• Patented technology: High-sensitivity, low-temperature cathode source
• Up to 9 fixed long-life Faradays with optional multiple ion counters for peak jumping
• Low volume design maximising sensitivity and lowering the instrument footprint
• Large radius electromagnet for optimal transmission, resolution, and stability
• Nier type source operates at 8kV accelerating voltage to maximise sensitivity across the mass range
• NGX is fully bakeable to 350°C and includes an in-line SAES GP50 getter pump ensuring a low background static vacuum
• Use of a fixed multi-collector greatly simplifies instrument construction, lowers the collector volume and increases effective sensitivity. It also greatly simplifies instrument operation since no zoom lens or movable optics are required
• An ultimate vacuum of 10^-10 mbar is achieved using 2 separate pumps: an 80 l/s turbo-molecular pump backed with an oil-free diaphragm pump and a 40 l/s ion pump
• Newly developed software providing unparalleled control and analysis for tailor made applications as well as repetitive analyses
• Fully networkable to permit remote control of the instrument

ATONA^®

The unique, patented ATONA (aA to nA) amplification technology from Isotopx has eliminated the need for a feedback resistor. The outcome is a significant reduction in amplifier noise, a dramatic increase in dynamic range, rapid amplifier decay, and improved baseline and calibration stability. But what does this mean for your analysis?

In practice, this means analysis of signal sizes from tens of counts per second to nanoamps (hundreds of volts) with lower noise than any resistor-based amplifier. So you can analyse a wider range of sample sizes than ever before, with more confidence in your data.

Preparation Systems

Sample introduction can be a challenging and time-consuming part of noble gas sample analysis. Isotopx supply extraction lines for preparation and clean-up of noble gas samples or standards. Our extraction lines are constructed from stainless steel and mounted on a flexible aluminium frame giving good accessibility during use and allowing for easier upgrades. All lines are software controlled and can be baked to 350 degrees Celsius to ensure clean preparation systems. A high level of customisation is possible during design and Isotopx work closely with the end-user to agree the final specification.
