Laboratory Snapshots of Ishida Lab


 A student is separating synthesized organic materials by a liquid chromatography.


 Elemental analysis of organic materials. C, H, N, and S can be analysed simultaneously.


 Fourier-Transform Nuclear Magnetic Resonance (NMR)---A powerful tool for the characterization of organic molecules.


 Apparatus of Gas-Chromatography/Mass-Spectroscopy (GCMS), an indispensable tool for the identification of synthesized organic molecules.


 Electron Paramagnetic Resonance (ESR/EPR) for the study of electron-spin states of magnetic materials.


 Superconducting Quantum Interference Device (SQUID). We can measure dc magnetic susceptibility and magnetization curve in 1.8 - 800 K and -7 - 7 T.


 Measurements of oxidation/reduction potentials of electron-donor/acceptor molecules by Cyclic Voltammetry (CV).


 Single crystal X-ray crystallography. We can determine precise atomic positions in crystals in the temperature range down to 100 K.


 Analysis of magnetic data.


 X-Ray fluorescence spectroscopy (energy-dispersion type). Qualitative and quantitative analysis from X-ray emmision of the elements involved.


 Physical-Property-Measurement System (PPMS). We can measure ac magnetic susceptibility, heat capacity, electrical conductivity, Hall effect, and magnetoresistance in 1.9 - 400 K and -9 - 9 T.
