Core Viewpoint - The article discusses the release of the "2025 Shandong Province Key Focus Directory for Newly Purchased Large Scientific Research Instruments," which includes nine categories of instruments aimed at optimizing resource allocation and enhancing the efficiency of scientific research in the province [1][2]. Summary by Relevant Sections Overview of the Directory - The directory includes nine types of scientific research instruments such as X-ray diffractometers, mass spectrometers, and flow cytometers, which are essential for various research applications [2]. - The directory serves as a critical reference for provincial universities and research institutions when purchasing large scientific instruments valued at 500,000 yuan or more [2]. Instrument Categories and Regional Distribution - The nine categories of instruments listed in the directory are: 1. X-ray diffractometer 2. Inductively Coupled Plasma Emission Spectrometer 3. Inductively Coupled Plasma Mass Spectrometer 4. Gas Chromatograph 5. Liquid Chromatograph 6. Flow Cytometer 7. Laser Confocal Microscope 8. Ultracentrifuge 9. Fluorescent Quantitative PCR Instrument [2][3]. - The distribution of these instruments across different cities in Shandong Province is as follows: - X-ray diffractometer: Jinan (56), Qingdao (36), Yantai (7), Dongying (6) [3]. - Inductively Coupled Plasma Emission Spectrometer: Jinan (27), Qingdao (25), Linyi (13), Binzhou (13) [3]. - Inductively Coupled Plasma Mass Spectrometer: Qingdao (44), Jinan (43), Weifang (20), Yantai (13) [3]. - Gas Chromatograph: Qingdao (22), Jinan (17), Yantai (11), Binzhou (8) [3]. - Liquid Chromatograph: Jinan (99), Qingdao (65), Yantai (41), Weihai (23) [3]. - Flow Cytometer: Jinan (109), Qingdao (36), Yantai (21), Jining (8) [3]. - Laser Confocal Microscope: Jinan (71), Qingdao (30), Tai'an (13), Jining (9) [3]. - Ultracentrifuge: Jinan (44), Qingdao (12), Tai'an (10), Yantai (9) [3]. - Fluorescent Quantitative PCR Instrument: Jinan (35), Tai'an (25), Qingdao (8), Binzhou (5) [3]. Implementation and Guidelines - Relevant institutions are required to conduct evaluations before purchasing new large scientific instruments, ensuring adherence to the directory and preventing unreasonable growth in the number of instruments listed [2]. - The initiative aims to enhance the utilization efficiency and sharing level of large scientific research instruments in Shandong Province [2].
