HyPix-Arc 150°: Curved photon counting X-ray detector


hypix-arc curved detector

The HyPix-Arc 150° is a unique, curved Hybrid Photon Counting (HPC) X-ray detector for single crystal diffraction applications. HyPix-Arc 150° has the highest 2θ range at a single position available for the home lab.

Collect more data in a single exposure with less reflection profile distortion:

The HyPix-Arc 150° offers 150 degrees angular coverage from edge to edge. This is more than enough to collect complete single crystal diffraction data, according to IUCr guidelines, for even Cu Kα X-ray wavelength from a single theta position. High and low angle data are measured at the same time, under the same conditions for better scaling, faster data and reduced dose time.

A curved detector minimizes peak distortion by ensuring that, even at short crystal-to-detector distances, diffracted beams are closer to perpendicular than is possible with a flat geometry.

Features:

  • Lowest reflection profile distortion
  • Faster data collection
  • Higher 2θ coverage in a single image
  • All reflections measured under the same conditions
  • Capture more diffracted photons per exposure

CrysAlisPro v40

Now with full 64 bit compatibility!

Rigaku Oxford Diffraction single crystal X-ray diffractometers come complete with CrysAlisPro, our user-inspired data collection and data processing software for small molecule and protein crystallography. Designed around an easy-to-use graphical user interface, CrysAlisPro can be operated under fully automatic, semi-automatic or manual control.

CrysAlisPro logo

The latest release, CrysAlisPro v.40, is now fully 64 bit compatible and ready for the future. As modern diffractometers increase in performance and speed, your experiments generate bigger and bigger images and datasets. Additionally, supporting large detectors with very high pixel counts, such as those more commonly found at synchrotrons, requires large amounts of memory. Moving to 64 bit gives applications access to more memory, enabling the handling of these very large image sizes and data sets.

Expanded support for older Rigaku instrumentation and third party hardware is also in this release.

See below for other new software features that have recently been introduced.

How to get CrysAlisPro

The software is freely available for users of Rigaku Oxford Diffraction single crystal X-ray instruments and can be downloaded from our forum. Please register at http://www.rigakuxrayforum.com. Any queries related to the software may be answered on the forum.

Processing of challenging and non-standard data collections

CrysAlisPro Ewald3D

CrysAlisPro contains a comprehensive and highly effective range of tools for tackling a wide range of samples from easy to challenging, and non-standard crystal samples. For example, EwaldExplorer and Ewald 3D (NEW!) easily identify effects, problems or artifacts in difficult or problematic datasets.

Ewald3D allows visualization of measured reciprocal space in 3-dimensions and in an undistorted way. Identifying diffuse scatter, modulation, subtle twinning, or incorrect instrument models is quick and easy with this brand new feature.

Supporting a range of crystallographic setups and applications

In addition to standard data collection routines, CrysAlisPro contains tools for working with non-standard experimental setups and sample types, including:

  • High pressure data collections
  • Variable temperature and multi-wavelength experiments
  • Powder experiments (data collection and processing)
  • Automatic screening or full data collections of several in situ protein crystals
  • Highly absorbing samples
  • Up to 8-fold twinned samples
  • Charge density measurements
  • Absolute structure determination
Software Compatibility

Exporting frames or data from CrysAlisPro into suitable alternative formats such as mosFLM, XDS, Denzo (HKL 2000) or another Esperanto format is easily achieved. Use CrysAlisPro’s data collection strategy to achieve the best data coverage in the quickest possible time and then automatically output into HKLF format for small molecule datasets or into the MTZ format for protein datasets.

CrysAlisPro is used by numerous research groups to process their synchrotron data. Our software is capable of importing data from several different detector types; known or unknown.

AutoChem

AutoChem is the ultimate productivity tool for small molecule chemists, offering fast, fully automatic structure solution and refinement during data collection. Developed in collaboration with OlexSys Ltd (Durham University, UK), AutoChem works in conjunction with Olex2 where more advanced structure solution and refinement functionality exists. AutoChem is seamlessly integrated within CrysAlisPro, and forms an integral part of our ‘What is this?’ feature.

The ‘What is this?’ feature gives you structures in seconds and ensures you are not wasting time collecting full datasets on known samples or starting materials. It is an alternative pre-experiment option, which is used to plan your full data collections.

bacsaI underestimated the impact a new system would have on the workflow and our ability to analyse multiple samples. It has allowed us to remain competitive, and to be able to provide the necessary service support for research groups in the department.

Dr. Henrik Friis, Natural History Museum at the University of Oslo

Friis Dr. Henrik Friis is Associate Professor in Mineralogy in the Natural History Museum, University of Oslo. Prior to the installation of the new XtaLAB Synergy-S system in early 2018, Dr. Friis had no direct access to a single-crystal X-ray diffractometer system: yet he depends upon single-crystal diffraction techniques extensively to advance his work in relation to a wide range of recently-discovered minerals and new materials research. With a large number of collaborators, worldwide, Henrik was in a position to collect some single-crystal data in the laboratories of his research partners and at a number of central research facilities. There were several reasons for purchasing the XtaLAB Synergy-S system, as discussed, below.

Dr. Samantha N. MacMillan, Cornell University

macmillanMy decision was ultimately cemented by doing a demo of the instrument and I would recommend that anyone considering making a purchase do one, either in person or virtually. I absolutely would recommend my new system – the combination of speed, quality and design has transformed the way that we are doing research in the facility.

Prof. Christine McKenzie, University of Southern Denmark

mckenzieThe “What-Is-This (WIT)” function means that students’ crystals can be checked more or less immediately. There is no longer the sense that we can’t waste our time and valuable machine time on crystals of well-known compounds.

ELement ANalyzer

Elemental analysis attachment for single crystals

The ELement ANalyzer is a state-of-the-art attachment that allows us to obtain qualitative information on elements in a single crystal at the same time as X-ray diffraction data collection for a single crystal structural analysis. By measuring the X-ray fluorescence spectrum emitted during X-ray diffraction experiments with the ELement ANalyzer, it becomes possible to perform elemental analysis on a single grain of crystal. The ELement ANalyzer can be used for confirmation the presence of central metal(s) in a mononuclear or polynuclear complex or solvent in a crystal for small molecule X-ray crystallography. There is a broad range of possible applications of the ELement ANalyzer in scientific fields.
