Analyze carbonate isotopes in the lab and the field without compromising sensitive equipment or slowing down your workday.

Carbonate Measurements: The Classical Approach

 In the classical method to analyze carbonates, you go to the sampling site, gather samples, and bring them to the lab to learn more about the past climate conditions.

For this you would usually use a mass spectrometer combined with a carbonate device.

This is the gold standard for carbonate analysis and produces quality results from small samples.

But what if your sampling or your sampling site was not good? Then your sample analysis creates some confusion in the big picture. What if you don’t get the chance to visit your sampling site again?

Push the Limits of Carbonate Measurements

carbonate-2Why don’t you bring your lab equipment along to the sampling site? Isotope ratio infrared spectrometry (IRIS) is portable and analyzes your samples wherever you are: in the cave, on the boat, in the car… wherever you are.

With IRIS you can analyze δ13C and delta δ 18O data from air, water, carbonate, DIC, and bulk carbonate samples – immediately in the field. This way you can measure your DIC and carbonate samples on-site and in real-time, and optimize your trip.

Bundle up the Strength of IRIS and IRMS

In the lab, Isotope Ratio Mass Spectrometry (IRMS) is the gold standard for carbonate analysis and produces perfect results from small foraminifera samples. IRMS when bundled with a Carbonate Device, provides you with the best possible data from small sample analysis. IRMS will provide you with the highest stability, sensitivity, and precision. You can generate data from just 20 μg of sample.



For Isotope Ratio Infrared Spectrometry (IRIS) you will need 200 μg of sample. But the big advantage is that you can measure samples immediately and in the field. It enables production of δ13C and δ18O data from water, carbonate, DIC, and bulk carbonate samples. It is simple and reliable based on its built-in referencing system, as well as the included and portable reference gas containers. With its ready-to-go software solution, you can start your measurements instantly.



·         When in the field, use IRIS to avoid transporting samples back to the lab. Focus on interesting sampling spots, and return with final results. Analyze up to 100 samples per day.

·         When in the lab, use IRIS to generate precision data quickly. Achieve high sample throughput for precision carbonate analysis – 46 samples a day. Benefit from total process control and data log files for complete insight into all preparation and measurement processes.
