Instrumentation lab



Instrumentation lab includes ICP-MS room and TIMS room

ICP-MS room


NEPTUNE PLUS (Thermo Scientific)

Introduced in November 2017. Equipped with nine Faraday cups and eight CDD detectors. Li, Hf isotope analyses, Ra quantitative analysis are carried out. We are currently preparing for isotopic analysis of Si, Fe and Ni, etc.


ELEMENT XR (Thermo Scientific)

Sector type ICP-MS. 18 element concentration + PGE concentration determination can be performed. The sample is decomposed with three different decomposition methods and measured by three different analytical sequences. The minimum necessary amount of sample to be solution for analysis is ~10 mg in case of basaltic rocks.

iCAP TQ ICP-MS (Thermo Scientific)

ICP - QMS. It is possible to analyze the concentration of 36 elements (Li, Be, B, Rb, Sr, Y, Zr, Nb, Mo, Cd, In, Sn, Sb, Cs, Ba, REE [La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu] Hf, Ta, Tl, Pb, Bi, Th and U) using samples of two different decomposition methods (total of 3 sequences). The minimum necessary amount of sample for analysis is about 2 mg in the case of Basaltic rocks.

iCAP-Qs (Thermo Scientific)

ICP- QMS. Perform in situ spot quantitative analysis of the polished specimen combined with laser equipment. U - Pb dating of Zircon, and trace element analysis such as REE are proceeded.

Analyte G2 Excimer Laser system (Teledyne)

Ar-F Excimer laser system. The wavelength is 193 nm. The system is used for in-situ spot analysis combined with ICP-MS (LA-ICP-MS). Currently, it is mainly connected with iCAP-Qs, for U-Pb dating of zircon, trace element analysis such as REE etc. are examined. According to the linkage to the Visual Stage system (see more info), it is easily set the analytical position precisely under the laser system while confirming the images and data obtained by the microscope, SEM and ion-probes. We have a plan that this equipment will be proceeding connect with Neptune plus and/or Element XR for the in situ spot analysis for much wider applications.
