The stable isotope software

ionOS is the most advanced stable isotope software ever created, developed to make your sample analysis effortless. With the increasing demand on the modern-day laboratory for ever more efficiency, ionOS is the ideal IRMS software to support you with your data analysis, saving you time and money whilst generating data more consistently. 

This feature-rich IRMS software has been designed from the ground up for the stable isotope analysis and works in concert with our stable isotope ratio mass spectrometers and inlet systems, providing exceptional automation and sophistication in your EA and GC data processing. When used in conjunction with one of our mass spectrometers, ionOS provides you with as much information as is necessary to verify that your IRMS system is working to specifications, and allows you to control sample runs and schedule tasks. Moreover, ionOS is also able to process third-party data, offering unparalleled gains for the entire stable isotope community.

What have our customers gained by using the ionOS IRMS software?

We really enjoy working with ionOS. All the gas analysis we did in the beginning of 2015 (more than a thousand samples) were calculated and validated with ionOS! We have saved a lot of time. It is very useful for batches of a hundred samples and to check standards.

Our lab runs whole crude oils with hundreds of peaks, of which only a select number are of interest. Peak mapping makes selecting only those peaks across large data sets a quick and easy process, saving us a huge amount of time and effort. Even when there is a change in retention time ionOS can determine where the peaks of interest have shifted to.

I’m VERY impressed by ionOS, especially the calibrations part. It’s basically doing what I always wanted other software to do, but it never seemed to work or wasn’t clear enough. This applies to a lot of chromatography quantifying packages I’ve used.

Dave Hughes // Lancaster Environment Centre, Lancaster University, UK 


Although I use a different IRMS instrument, I use ionOS for the processing of my GC isotope data. ionOS has sharply accelerated my work thanks to the great convenience, user-friendly interface, and advanced functionality: thank you!  
I love ionOS and I also feel the huge potential of ionOS in the future, which will very much contribute to our isotope science community.

Gain time

ionOS offers a vast array of powerful features, delivering considerable time savings to almost every stable isotope lab in the world. Whether handling data from multi-elemental (NCS) analysis or a complex GC separation of 100’s of sample compounds, stable isotope analysis generates large data sets. With our ionOS IRMS software, processing these complex data sets is reduced to a small number of automatic functions, saving you large amounts of time.

Gain simplicity

ionOS presents a clean user interface with clear iconography and structure, which makes it simple to use. Developed with collaborative input from our friends in the stable isotope community, you can be sure that the functionality you want is available within ionOS and is intuitive. The integrated, powerful search functionality gives you the ability to easily find your data, facilitating the management of large stable isotope data sets.

Gain data interpretation

After working hard to collect, prepare, and analyze your samples, the – usually - complex task of data interpretation begins. ionOS goes further than any other stable isotope software to make your data interpretation easy. ionOS is the only IRMS software to automatically provide multi-elemental, multi-point isotope calibration of results for immediate interpretation. Coupled with our unique Peak Maps feature, which instantly identifies GC compounds across multiple injections, you will have confidence in the validity of your data.

Gain data standardization

Standardization of stable isotope data is crucial for collaboration across different laboratories. As a company dedicated to stable isotope analysis, we understand it is our duty to simplify this process. This is the reason why we have put data standardization at the heart of our ionOS stable isotope software. ionOS lets you define a library of isotopic standards which can be used to perform automatic multi-point isotopic calibrations and generate consistent results.

Gain data management

When handling large data sets, it is imperative that the data remains organized and easily searchable. ionOS makes this incredibly simple with the use of batches and its integrated search functionality. Samples can be added to batches at acquisition time or added retrospectively, giving a large degree of flexibility to how your data is managed.

Gain more

ionOS offers more than any other stable isotope software, and our customers agree. This is why we have made ionOS available to the entire stable isotope community. Even if your data is generated using another manufacturer’s instrument, you can import your third-party data and still benefit from the power of ionOS. By powering your research with ionOS, you can be sure that you will have access to our exciting future innovations through automatic updates.
