國立臺灣師範大學貴重儀器使用中心服務計畫

The Instrumentation Center (IC) was established on the campus of National Taiwan Normal University (NTNU) in 2011 March, which belongs to the Department of Research and Develop of NTNU. Currently, the twenty-one advanced facilities are managed by the IC; mostly, seven state-of-the-art facilities among them are incorporated in the service project of Ministry of Science and Technology (MOST) and listed as following: 1. Nuclear Magnetic Resonance (NMR, Bruker AvanceIII HD-600 MHz, Bruker) In addition to regular parts, the TBO probe and auto-loading system are set in the NMR. The TBO probe is specially made for a resonance of three various nuclides, i.e. 1H/19F/BB.In addition, two professors in Department of Chemistry are assigned to organize and evaluate the operation of this instrument. Moreover, in 2019, the majority of samples (90%) are from other universities and industrial companies. 2. High Resolution Mass Spectrometer (HRMS, JEOL JMS-700, JEOL) The HRMS provides electron ionization (EI) or fast atom bombardment (FAB) to ionize samples. Most of all, the small molecular materials are suitable for both these ways. The excellent performance in 2019 is that amount of samples is 2346. 3. Dual X-ray Single Crystal Diffractometer (SXRD, Bruker D8 Venture, Bruker) Thanks to its smart mechanism, not only is the SXRD an energy-saving style, but it also enhances work efficiency. The main analysis includes determinations of crystal system or lattice constant, data collections of X-ray single crystal diffraction, and analyses of crystal microstructure. In 2019, the number of samples from out of NTNU is 81 % in the total amount. 4. Laser Scanning Confocal Microscope System (LSM, ZEISS LSM880 with airyscan, ZEISS) The LSM has been widely adopted to get single-point high resolution image, owing to its effective elimination of noise; it has been broadly used to observe the profiles of fluorescence-labeled samples upon varied time or cross section. The skills of live cell imaging and high-content imaging system have been applied in this system, as well. The good grade in 2019 is that amount of samples are 1114. 5. High Resolution Electrospray Mass Spectrometry (HR-ESI MS, AB SCIEX QSTARR XL, AB SCIEX) Electrospray Ionization (ESI) is an important evolution for MS examinations, which extends MS tests to the biological field. ESI supplies the researches of protein with an efficient and accurate testify. The accomplishment in 2019 is that amount of samples is 1163. 6. X-ray Powder Diffractometer (PXRD, Bruker D8 Advance, Bruker) The PXRD has been extensively used to obtain the XRD patents of inorganic materials, such as metals, semiconductors, alloys and so on. Furthermore, all crystalline parameters of detected samples could be evaluated via the XRD patents. The accomplishment in 2019 is that amount of samples is 590. 7. Electron Paramagnetic Resonance (EPR, Bruker EPR-plus, Bruker) The EPR, a spectroscopic technique, detects species in which unpaired electrons exist. Plenty of materials have unpaired electrons, including free radicals, many transition metal ions, and defects in materials. The studies of EPR crosses several subjects, including chemistry, physics, biology, materials science and medical science. The achievement in 2019 is that amount of samples is 702.
