Desktop Diffractometer MD-10 with Position-Sensitive Detector
This unique device has dimensions
and weight of a microwave oven, however it performs phase analysis of powders
and solid materials with accuracy and speed comparable to those of full-scale
laboratory instruments! And what is still better, it is also much cheaper
than its large and heavy rivals.
This is the most price efficient
solution for mobile laboratories on cars, ships, helicopters and other
transportation facilities, nuclear power stations, small industrial control
laboratories, educational laboratories, etc., and may be used successfully
in geology, ocean studies, ecology, forensic science and many other applications.
Specific features of the device:
-
Debye-Scherrer geometry, horizontal sample
orientation, spinning sample holder,
-
No goniometer and other precision mechanics,
-
Optical microscope for accurate sample
positioning,
-
Two incident-beam monochromators improve
signal to noise ratio and double the angular range of the detector,
-
Sealed-off curved position-sensitive
detector with curvature radius 114 mm and Methane-Argon-Xenon gas
filling,
-
Precise 12-bit ADC provides high resolution
and angular measurement accuracy,
-
Low power air-cooled X-ray tube
with stabilized focus position,
-
High-frequency solid-state single block
HV power supply,
-
AC and DC feeding (optional) is possible
from mains or a battery,
-
Compact electronic control and data
acquisition system in a single module,
-
Small weight, small dimensions, low
price
-
Real-time data processing with MS Windows
software,
-
Low tube power, radiation protective
enclosure and safety interlocks guarantee the safety of the personnel.
To illustrate the device capabilities a diffraction
pattern from corundum sample is shown below. The acquisition time was 800 sec.
