Highly sensitive, accurate and fast analyzer, reliable measurement of δ13C, δ18O, CO₂and H₂O

ABB LG R-I cosBuilding on the long history and outstanding performance of Los Gatos Research analyzers, the gas analyzer uses patented off-axis integral cavity output spectroscopy (OA-ICOS) technology, the latest evolution of tunable diode laser absorption spectroscopy (TDLAS).

Isotope measurements of carbon dioxide can determine the migration, absorption, residence time, storage and consumption patterns of carbon dioxide throughout the atmosphere and biosphere.Carbon dioxide is a gas particularly useful in such analysis because it exists in the metabolism of organisms and is a by-product of the combustion process.When performing carbon dioxide isotope measurements, scientists need to:

(1) Perform accurate measurements over a wide range of molar fractions

(2) High precision

(3) Even if the proportion of mixed gas composition changes rapidly, it can be accurately measured

(4) Good portability

(5) User-friendly interface

(6) Low drift

(7) For H₂S, NH₂and methane and other hydrocarbons are insensitive.

ABBThe patented OA-ICOS technology is the fourth generation of optical cavity enhanced absorption technology.Compared with traditional fragile cavity decay spectroscopy technology and direct absorption technology, this technology has many advantages.The LGR-ICOS analyzer is simpler and more robust, providing users with higher performance and reliability while reducing operating costs.

The analyzer is insensitive to lens alignment, has a short measurement time, does not require strict control of the pressure and temperature in the cavity, and does not require expensive and power-consuming auxiliary components.The analyzer includes an internal computer that can store data on its internal hard drive almost indefinitely (for applications requiring unattended long-term operation) and use its analog and digital (RS232) output to real-time data.Send to the data logger.There are several optional features available to improve flow time response, allow multiple measurement source gas inputs, or remote access and control of the analyzer over the Internet.
