IAEA researchers use the LGR water isotope analyzer to measure high 2H enriched water samples
Researchers at the International Atomic Energy Agency (IAEA) published an article using the LGR Water Isotope Analyzer (912-0032) to measure high 2H enriched water samples. The article has two purposes: The article also briefly describes the use of CRDS analyzer to measure high 2H enriched water samples (CRDS water isotope analyzer can measure δ2HVSMOW-SLAP samples with a value of about 750 ,, but more than 20 times between two samples need to be Injections can remove significant memory effects, so in fact only 15 samples can be measured per day). In 2015, IAEA (Vienna, Austria) announced the use of new 2H- (and 18O-) enriched HDO benchmarks. All δ2HVSMOW-SLAP calibrations use the OA-ICOS technology water isotope analyzer. [Translator's Note: Please note that the IAEA researchers use the LGR water isotope analyzer using OA-ICOS technology instead of the CRDS technology, which means that the LGR water isotope analyzer can be used as an analyzer for making IAEA standards. The LGR analyzer is more accurate, more accurate and more stable. 】 The IAEA article describes four key advantages of the LGR water isotope analyzer: Conclusion: The LGR water isotope analyzer has high performance, low cost of consumables, easy to use, and can be quickly switched back to the stable isotope analysis of natural water samples. It is the leader in similar water isotope analysis instruments. (Note: This article is an independent article published by IAEA researchers. It is authoritative, objective, and independent, and can be widely used.)

(1) Demonstrate that the water isotope analyzer based on OA-ICOS technology can quickly obtain the δ2HVSMOW-SLAP values ​​of high-accuracy and high-precision natural abundance water samples and deuterated water samples (delta_2H ~ +57,000‰);
(2) Subsequent demonstration of the effectiveness of the water sample based on the laser 2H enrichment method to facilitate the productivity of the batch 3H electrolysis enriched environmental drowning laboratory. 
1. Accurately measure high-enriched HDO water samples (delta_2H ~ +57,000‰) with a content of up to 9000ppm. The accuracy and accuracy are the highest levels that can be achieved by measuring natural water samples.
2. Within 1 hour after measuring the highly enriched sample, the user can apply the same settings to measure common natural water samples and quickly eliminate the memory effect. This can be done without an isotope mass spectrometer;
3. The article reports that the LGR water isotope analyzer can measure 60 highly enriched water samples per day;
4. The high performance of the LGR water isotope analyzer described in the article can be implemented on all EP models of water isotope analyzers without special settings.
