○Subject and Objectives

The Laboratory and Analysis Division organizes three types of collaborative study in the Phase III Medium-Term Plan.

(1) Research collaboration with research projects: The division manages eighteen basement laboratories dedicated to various analytical needs. The division is responsible for maintaining state-of-the-art facilities, especially stable isotope mass spectrometers, and collaborates with research projects. 

(2) Research collaboration with core projects: A core project FR entitled “Proposal and verification of the validity of isotope environmental traceability methodology in environmental studies” seeks to establish a methodology for how to use the concept of environmental traceability using multiple isotope ratios. The division collaborates with the project in an analytical viewpoint.

(3) Research collaboration with universities via “Environmental Isotope Study”: The division provides “Joint Research Grant for the Environmental Isotope Study” for universities and affiliated institutions throughout Japan, allowing them to use the facilities and exchanging research information. From the FY2016, the division has started the two types of collaborations, “Collaborative research with the Division” or “General collaborative research”.

○Progress and Results in 2017

The division upgraded or maintained various analytical instruments in the laboratories.

The division accepted 18 proposals of “Collaborative research with the Division” and 46 proposals of “General collaborative research” in FY2017 of “Joint Research Grant for the Environmental Isotope Study”.

The division organized a session in JpGU2017 entitled “H-TT23: Development and applications of environmental traceability methods” on 23 May 2017. 18 oral and 15 poster papers were presented in the session. 

The division organized a short course of Environmental Isotope Study: Course 1 for light elements (29 - 31 August) and Course 2 for heavy elements (5-7 September). 16 researchers attended the course.

The division organized the sixth annual symposium of Environmental Isotope Study on 22 December. 137 researchers and students attended the symposium.
