High Resolution ICP-MS


Finnigan ELEMENT XR, Thermo Fisher, installed in 2023.
This instrument is a double focusing magnetic sector field ICP-MS. It is able to fully automatically change between three fixed resolutions by switching the positions of the entrance and exit slits in < 1 s. High resolution simply distinguishes the analyte from interference by difference in mass. This ability can be used for quantification and isotope ratio analysis for nearly the whole periodic table. Detection limit is as low as a ppq level.

Quadrupole ICP-MS


NexION 350D, Perkin Elmer, installed in 2015.
This is a quadrupole ICP-MS with a universal cell between the ion lens and the quadrupole mass spectrometer. Using the reaction mode, molecular ions can be eliminated by the reaction with reaction gas, such as NH3. Thus, the detection limit of atomic ion, such as Fe+, can be improved significantly. Some 70 elements can be measured simultaneously at a concentration level as low as ppt. This instrument is used for monitoring heavy metals in waste water from Uji Campus and also for research.



SPECTRO BLUE, SPECTRO, installed in 2012.
This ICP optical emission spectrometer is equipped with a Paschen-Runge optical system and charge-coupled device detectors, realizing simultaneous measurement of a number of atomic lines. Detection limit is as low as a ppb level.



TRACE GC2000-DSQ, Thermo Fisher, installed in 2003.
This instrument is equiped with a Dual Stage Quadrupole to virtually eliminate source noise before it reaches the MS detector. This instrument is used for monitoring volatile organic compounds in waste water in Uji Campus.

Automated preconcentration system for trace elements


SPE-100, HHigh-Tech Fielding.
This system realizes simple and rapid preconcentration of trace elements from water samples. Contamination during the preconcentration can be significantly low. We have developed this system in cooperative study with HIRANUMA SANGYO and Hitachi High-Tech Fielding.

Clean room laboratory for chemical experiments

clean room

SANKI, installed in 2010.
The class 1000 clean room is desinged for chemical experiments of trace elements.
