All Amptek x-ray detector elements are available in either the XR100 or X-123 configuration. The XR100 configuration includes the detector and preamplifier only and must be paired with the PX5 digital pulse processor, MCA, and power supply to be a complete system. The X-123 includes the digital pulse processor, MCA, and power supply and is a complete system. The XR100/PX5 combination is the most flexible and is designed for laboratory use. The PX5 can be used with other detectors, including other manufacturers'. The X-123 configuration is ideal for OEM and custom applications where size and portability are considerations.
