MR Diffusion

MR扩散是研究分子运动的强大而广泛的方法，例如布朗运动，翻译运动和流动。

专用的扩散探针是提供增加分辨率和Q空间实验中分辨率的最终工具。高梯度强度和快速切换时间可实现扩散系数的样品的扩散研究5 x 10^-15m²/s，从而可以在较大范围内检测各种扩散时间，并研究X-核中，这需要高梯度强度。

MR扩散配件和MR显微镜配件共享相同的硬件平台，从而可以使用成像配件的梯度放大器驱动扩散梯度线圈。

布鲁克（Bruker）为MR扩散提供了完整的硬件和软件配件软件包，可以轻松地将其添加到具有标准孔（52毫米），宽孔（89毫米）或超宽孔（154毫米）磁体的现有avance光谱仪中。

This accessory provides state of the art MR Diffusion capabilities, very strong gradients together with high resolution MR probe technology together allowing to extend the high-resolution spectroscopy seemlessly into the range of big, slow diffusion molecules. On the other hand it also allows investigating more exotic systems, e.g. porous media.

The MR Diffusion accessory is a user-friendly routine diffusion package which contains both state-of-the art hardware and software which enables non-expert and expert user to take full control of their MR experiment - whether running routine diffusion investigation or developing highly sophisticated diffusion sequences.

MR Diffusion Probes

MR扩散探针可用于SB，WB和SWB系统。SB探针还适合较大的孔磁铁，并提供1H-19F/XBB，并锁定BBI或BBO配置以及自动调整和匹配以及较宽的温度范围。WB探针具有可交换的RF线圈的各种直径为1H，X-核肠带可作为单个或双重调谐。

硬件

Bruker MR Microscopy / MR Diffusion hardware is flexible and powerful, whether performing routine measurements, creating new demanding methods or investigating new types of objects. Bruker Great60 gradient amplifier combines strong gradient pulses with up to 60 A and fast switching times with stability over a large bandwidth, low distortion, linearity and low noise.

The MR Diffusion cabinet is required for all Bruker wide bore or standard bore diffusion gradient coils, requiring one gradient amplifiers. To enable high performance applications with large current amplitudes, fast switching and high duty cycles all MR Diffusion gradient coils are water cooled by a close looped water chiller with built-in temperature, cooling fluid level and flow rate remote monitoring.

Thediff软件包is a comprehensive software to simplify the set-up of diffusion experiments. To focus on physically relevant diffusion parameters, machine level settings are replaced by experiment level parameters. For example, rather than setting the gradient strength in percent, the gradient strength is given in physical units. The user can select between Gauss/cm, mT/m, T/m and Hz/cm (1H). For experimentally relevant parameters, like the diffusion time, thediff程序计算所有relevant delays building the diffusion time and provides a lower limit given by the unavoidable delays in the sequence. In other words, the users do not need to know, which delays form the diffusion time, they only need to specify the diffusion time and the program will automatically set the other parameters. Most of the parameters will be checked for reasonable upper and lower limits.

Thediffprogram covers the standard diffusion/DOSY experiments. It also offers a couple of “2D” methods, where “2D” stands for 2 non-FT or dynamic dimensions, for example like DDCOSY having 2 orthogonal diffusion dimensions, or DRCOSY having a diffusion and a relaxation dimension. The number of available methods will continue to grow in the future.

There are also new setup experiments and pure T1 and T2 experiments.
