Sistemas de difracción de rayos X de monocristal basados en HPAD

Determinación de la estructura de monocristales

XtaLAB PRO MM007

El XtaLAB PRO MM007 está diseñado en torno a la popular tecnología HPAD (Detector Híbrido de Pixeles de Matriz) Este sistema se puede configurar con una fuente de rayos X de ánodo rotatorio de longitud de onda única o doble, adecuada para una amplia variedad de tipos de muestras, a partir de estructuras inorgánicas a compuestos orgánicos y MOFs.

El detector casi perfecto, basado en los últimos avances HPAD, amplía enormemente las capacidades de los sistemas en términos de la velocidad de la adquisición de datos y de una medición más precisa de los datos débiles. El detector estándar en la serie XtaLAB PRO es el PILATUS3 R 200K, el cual ha sido probado en el campo y está fundamentado en la misma tecnología adoptada por las líneas de haz de sincrotrón en todo el mundo. Las características sobresalientes de estos detectores aseguran que cada difractómetro XtaLAB PRO producirá los mejores datos posibles para la fuente de rayos X seleccionada.

PILATUS3 R 200K: Low maintenance, direct photon counting detector



The PILATUS3 R 200K is a hybrid photon counting (HPC) detector designed to achieve the best possible data quality for diffraction experiments. HPC detectors are direct-detection, single-photon counting devices that have essentially no noise and high sensitivity. Moreover, the high dynamic range excellent DQE characteristics for the PILATUS3 R 200K means that they it is well suited for accurately measuring weak reflections alongside very strong reflections - overload corrections and separate scans for weak and strong data are not necessary. The readout time for the PILATUS3 R 200K is 7 msec readout speed, making it capable of true shutterless data collection, thus removing errors associated with shutter open/close and goniometer start/stop events. HPC detectors have revolutionized the way data are collected at synchrotrons and the PILATUS3 R detectors bring those same capabilities to collect the best possible data at home.
