布鲁克 BRUKER D8 Venture X 射线单晶衍射仪用途：广泛应用于化学、材料、生物、能源等领域，可精确测定无机物、有机物、金属配合物等结晶物质的三维空间结构与电子云密度，也能分析孪晶、无公度晶体、准晶等特殊材料及药物、生物大分子结构。技术原理：通过 Mo/Cu 钻石微焦斑双靶发射 X 射线，照射到高度有序的单晶样品上，晶体中规则排列的原子或分子对 X 射线产生相干散射。依据布拉格方程，当入射 X 射线波长与晶面间距及入射角满足特定条件时，各晶面的散射波会发生相长干涉形成衍射斑点。探测器记录这些衍射点的位置和强度分布，结合对称性分析、傅里叶变换等数学方法，重构出晶体的三维电子密度分布，进而确定晶胞参数、空间群、原子坐标及键长键角等结构信息。性能：具备 Mo 和 Cu 两种光源，Mo 光源功率≥1800W，管电压 10 - 60kV，管电流 2 - 80mA，稳定性 ±0.005%；Cu 光源为高强度微焦点 Cu 光管，功率≥50W。配备四轴（φ、2θ、ω、Kappa）测角仪，重复精度≤0.001°。探测器为 Photon Ⅲ CPAD 探测器，有效面积≥100×140mm²，具有 shutterfree 功能，采用风冷模式制冷，兼具单光子计数和积分计数模式。配有 Oxford Cryostream 1000 液氮低温系统，温度范围 80 - 400K，控温精度 ±0.1K 。焦斑尺寸≤110 微米，检测量子效率（DQE）≥0.95 ，彩色视频显微镜放大倍数 30~110 倍，分辨率≤3μm。
Product Name: Bruker BRUKER D8 Venture X-ray Single Crystal DiffractometerUsage: Widely used in fields such as chemistry, materials, biology, and energy. It can accurately determine the three-dimensional spatial structure and electron density of crystalline substances like inorganic substances, organic substances, and metal complexes. It can also analyze special materials such as twins, incommensurate crystals, quasicrystals, as well as the structures of drugs and biological macromolecules.Technical Principle: X-rays are emitted through Mo/Cu diamond micro-focus dual targets and irradiated onto highly ordered single crystal samples. Atoms or molecules regularly arranged in the crystal produce coherent scattering of X-rays. According to Bragg's equation, when the wavelength of the incident X-ray, the interplanar spacing, and the incident angle meet specific conditions, the scattering waves of each crystal plane will undergo constructive interference to form diffraction spots. The detector records the positions and intensity distributions of these diffraction points. Combining mathematical methods such as symmetry analysis and Fourier transform, the three-dimensional electron density distribution of the crystal is reconstructed, and then structural information such as unit cell parameters, space groups, atomic coordinates, bond lengths, and bond angles is determined.Performance: It has two light sources, Mo and Cu. The Mo light source has a power of ≥1800W, a tube voltage of 10 - 60kV, a tube current of 2 - 80mA, and a stability of ±0.005%. The Cu light source is a high-intensity micro-focus Cu light tube with a power of ≥50W. It is equipped with a four-axis (φ, 2θ, ω, Kappa) goniometer with a repeat accuracy of ≤0.001°. The detector is a Photon Ⅲ CPAD detector with an effective area of ≥100×140mm², having a shutterfree function, using air-cooled refrigeration, and having both single-photon counting and integral counting modes. It is equipped with an Oxford Cryostream 1000 liquid nitrogen low-temperature system with a temperature range of 80 - 400K and a temperature control accuracy of ±0.1K. The focal spot size is ≤110 microns, the detection quantum efficiency (DQE) is ≥0.95, the color video microscope has a magnification of 30 - 110 times, and the resolution is ≤3μm.
