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.

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. With

• Diffracted-Beam Monochromator: Ensures
high resolution and signal to noise by
removing Kβ, continuous x-rays, and sample
fluorescence from the diffracted beam.
