EA-i3211 Carbon Isotope Analyzer

AMBA EA-i3211 Carbon Isotope Analyzer is a high reliability low running cost isotopic carbon analysis system for bulk organic and inorganic samples. Combining mid-infrared Quantum Cascade Lasers (QCL) with String Topology Waveguide (STW) technology has enabled a breakthrough cavity volume of less than 0.1mL. Combined with Dumas flashover technology, the resulting small volume sample path results in fast sample turnover rates with low sample volume requirements compared to previous technologies opening up the range of analytical possibilities.

The AMBA EA-i3211 is extremely versatile enabling the analysis of both liquid and solid samples with sample size requirement as low as just 0.2mg of carbon. Thanks to the absence of a GC column the system adapts to a range of sample weights and sample types with differing carbon content. Compared with traditional isotope ratio mass spectrometers and other laser-based isotope analyzers, the EA-i3211 has better repeatability and speed. It is the best tool for isotopic carbon measurement in food science, soil science, ecology, marine biology, materials science, proteomics, oil and gas and other fields.

All AMBA analyzers can be controlled remotely via the Internet enabling operators to obtain and share data from measurements in remote locations and allowing continuous monitoring of the instrument for optimum performance.

AMBA analyzer ownership includes instrument life-time access to our one-to-one customer service and technical support, right from product purchase, through to system integration and beyond.
