R-AXIS SPIDER large area curved imaging plate detector

Finally a small molecule system that is experimentally versatile and extremely easy and inexpensive to maintain.

The large imaging plate format of the SPIDER provides outstanding versatility that cannot be matched by CCD-based detectors.

Compare the SPIDER aperture to the size of a typical CCD

• Routine small molecule analysis is exactly that: routine. The large aperture and lack of the dark current associated with CCD detectors, allows rapid and complete data collection on standard samples. No need to worry about collecting the full resolution of diffraction since the large aperture automatically collects the diffraction limit with Mo radiation.
• Absolute configurations of organic molecules could not be easier. Switch your tube to Cu and the large active area of the detector provides simultaneous measurement of -60° to +144° in 2θ, more than enough for a publication quality structure.
• Weak or poorly scattering crystals are easily handled due to a number of factors. The lack of a dark current (an attribute of any CCD detector) means that long exposures are not degraded by electronic noise.
• High quality electron density studies are achieved by a number of special attributes, specific to imaging plate technology. Error in measurement is reduced by a lack of dark current. Inter-image scaling features are reduced because so many more reflections are measured on a single image as compared to CCD detectors. The high dynamic range of the imaging plate as compared to CCD detectors provides the ability to measure weak and strong reflections accurately during the same scan.
• Versatile Experimentation is achieved by a phosphor that is essentially independent of radiation for Ag, Mo, Cu and Cr. The large aperture is ideal for measurement of powder samples, diffuse scattering or other specialized experiments that might be imagined.
• Easy and cheap to maintain. Imaging plates do not require a detector cooling system, which automatically reduces the device's overall complexity. There is no component in a SPIDER (like a CCD chip) that, if failed, would be catastrophically expensive to replace for someone without a service contract. As with all Rigaku detectors, Rigaku manufactures the SPIDER and will support the product long into the future.
