液态水同位素分析仪 (δ2H, δ18O)

In 2006, LGR (now under ABB Canada) launched a liquid water isotope analyzer based on OA-ICOS technology. After a long period of testing, the International Atomic Energy Agency (IAEA) was very satisfied with its performance and specially wrote and produced an operation manual and video CD for the LGR liquid water isotope analyzer. In the preface of the operation manual, the IAEA generously praises and predicts that the LGR analyzer will bring a methodological revolution to stable isotope measurement.

In just a few years, there have been over 600 LGR liquid water isotope analyzers worldwide, operating stably in various industries and publishing a large number of literature. The data has been widely recognized in various fields. The changes predicted by the IAEA have quietly arrived.

In early 2010, LGR launched an enhanced liquid water isotope analyzer (912-0008), which is a laser liquid water stable isotope analyzer that combines high speed and high accuracy. This device is capable of measuring liquid water samples¹⁸O/¹⁶The isotopic ratios of O and D/H have accuracies of 0.1 ‰ and 0.3 ‰, respectively. 1080 injection measurements can be taken per day, which means that one measurement can be completed every 80 seconds, and 150 unknown samples can be measured per day.

In 2013, LGR introduced the ability to simultaneously measure δ²H,δ¹⁷O,δ¹⁸The Triple liquid water isotope analyzer (912-0050) of O adopts LGR's internal temperature control technology to ensure smaller instrument drift and provide higher accuracy and precision, δ¹⁸O and δ²The accuracy of H can reach incredible 0.02 ‰ and 0.15 ‰!

Performance testing:

Measurement accuracy and precision superior to isotope ratio mass spectrometer	Linear and Range----Large scale isotope ratio measurement
Comparison analysis was conducted between LGR liquid water isotope analyzer and data from 5 different mass spectrometry laboratories. Fifty LWIA-24d analyzers were used to measure liquid water isotope standards (δ D: -79.00 ‰, δ 18O: -11.54 ‰), and the results verified the excellent performance of the analyzers (high accuracy, precision, and repeatability), R²>0.99999.	The linearity and range of LWIA-24d were extensively tested, with a measurement range of -454.3 ‰ to+1701 ‰ for δ D and -58.62 ‰ to+266.8 ‰ for δ 18O, R²>0.99999.
