The Rigaku Journal Vol. 17/ No. 2/ 2000 Product Information The New Standard of X-ray Dfffraction Rigaku Automated Powder X-ray Diffractometer The Multiflex is a powerful tool for materials development and evaluation The MultiFlex sets the new standard of compactness, safety, and ease of use in X-ray powder diffraction 1. Introduction X-ray diffractometers find wide application from quality assurance to materials research, covering new materials, ceramics, metals, minerals, semiconductors, polymers, and more with a variety of sample types. The MultiFlex is newly designed to meet such diverse measurement requirements. Its compact thetatheta goniometer holds a sample in a horizontal and 60 stationary position, eliminating the possibility of sample spillage during a measurement. It also allows simple handling of samples regardless of the sample shape, size, or type. The MultiFlex measurement software allows users to define multiple scan procedures for repeated use. Comprehensive analysis software enables phase identification, profile fitting, and other varied applications. The Rigaku Journal 2. Features (1) Sample Stays Horizontal Theta-Theta Goniometer The sample is mounted horizontally, which is an ideal configuration when dealing with large or irregular samples, loose powders, or a high-temperature stage. (2) Compact, Space-Saving Design Because lab space is often at a premium, the system's footprint is now reduced by 40% compared with other models of Rigaku stand-alone X-ray diffractometers. Casters are provided for ease of moving the system. an optional sample changer, multiple samples can be loaded and measured with individual procedures to increase throughput. (5) A Variety of Attachments (Optional) • Six-Sample Automatic Sample Changer: Enables up to six samples to be measured in succession. With its integrated sample spinning mechanism, this device effectively measures samples having large grains or preferred orientation. • High-Temperature Attachment: Enables programmed heating and cooling studies from ambient to ~1500EC under software control. Study the effects of thermal processing conditions on material properties. (3) Safety Design Safety interlocks and automatic alignment ensure safe and convenient operation. (4) Rigaku Measurement Software (Optional) Powerful, flexible software handles system alignment, X-ray generator control, routine measurements, and control of the optional high-temperature attachment. Real-time data display allows you to see the results as each data point is collected. Predefined measurement conditions and an intuitive interface make the system accessible even to beginners.
