Measurement in a short time using the D/teX Ultra

Background

The MiniFlex can be equipped with the D/teX Ultra high-speed 1-dimensional detector to obtain greater intensity. By using this detector, it is possible to obtain intensity a few tens to roughly 100 times greater than with a scintillation counter, and this enables a dramatic shortening of measurement time. Fig. 1 shows the diffraction profiles obtained with a scintillation counter and the D/teX Ultra high-speed 1-dimensional detector. The D/teX Ultra detector measures data faster because it can measure a wide range of 2θ simultaneously with good angular resolution.

Using the D/teX Ultra high-speed 1-dimensional detector is effective not only for rapid measurement, but also for detecting trace components. Fig. 2 shows the X-ray diffraction pattern and qualitative analysis results for a mineral sample, obtained in a measurement time of 1 minute. This enables qualitative analysis, with good sensitivity, and evaluation in an extremely short measurement time of mixed mineral samples with multiple components.
