The new single crystal diffractometer with dual X-ray sources will be part of the diffractometer equipment park in the X-ray service department for structure analysis of Organic Chemistry Institute and will be used for structural elucidation of new compounds. Currently for this purpose are available a single crystal device with a conventional copper X-ray source and a classical CCD detector and a second device equipped with two microfocus X-ray sources (Cu and Mo) and an upgraded detector. One machine was purchased cost-effective with Institute funds as a used device and reaches at this point 15 years life-cycle, by this reason it currently leads to frequent breakdowns. The second available X-ray unit is older than 9 years and is used intensively at maximum work capacity. A third X-ray single crystal diffractometer (a rotary anode machine) has been taken out of service in 2022 after more than 25 years of use. The decommissioning of this very old X-ray machine and the most frequent failures of the diffractometer with the conventional copper X-ray source slow down considerably the operation of the service department and make this replacement urgent.

新的双X射线源单晶衍射仪将成为有机化学研究所结构分析X射线服务部衍射仪设备园的一部分，用于新化合物的结构解析。目前，用于此目的的是一个单晶设备与传统的铜X射线源和一个经典的CCD检测器和第二个设备配备有两个微焦点X射线源（铜和钼）和升级的检测器。一台机器是用研究所的资金购买的，具有成本效益，作为一个二手设备，在这一点上达到15年的生命周期，由于这个原因，它目前经常导致故障。现有的第二台X光机已使用了9年以上，并以最大工作能力密集使用。第三台X射线单晶衍射仪（旋转阳极机）在使用超过25年后，已于2022年停止使用。这台非常旧的X射线机的退役以及使用传统铜X射线源的衍射仪最频繁的故障大大减缓了服务部门的运作，并使更换变得紧迫。
