In August 2011, another new LGR liquid water isotope analyzer LWIA-24d was settled in China. The instrument was installed at the national field observation station of CERN at the Fukang station. At the same time, LICA's LI-2000 vacuum extraction system was also available. This is the second water isotope analyzer purchased by Xinjiang Biogeography. On the side, the application of stable isotope data is more and more extensive.
