Quality control in industrial processes with phase identification

Ensuring quality control can be a daunting task in industrial processes. The key to a quality product is to maintain that quality throughout the entire process and having the appropriate materials is essential to this accomplishment. The wrong materials could alter the properties of the desired product. It could even change the product and everyone would certainly want the finished product to be able to function with its desired task. Observe the white powder in Figure 1. If one had ordered Al2O3 and observed this clean looking white powder; perhaps no questions would be asked.

Quality control of incoming products and reagents is easy with the MiniFlex. Observe the diffractogram overlays of Al2O3 in Figure 2. In a matter of minutes one can determine if they have the right materials or not. The pattern in blue is a typical diffractogram of corundum. The pattern in black is corundum that has been contaminated with talc. Provided a reference pattern, one may not require phase identification. However, if you are interested in what the contaminate may be, phase identification is required. If you do, make sure you collect all the data you need. Expecting the first corundum peak around 25.58° 2θ could cost you valuable information.

The fifth generation MiniFlex is a general purpose X-ray diffractometer that can perform qualitative and quantitative analysis of polycrystalline materials. The MiniFlex is available in two variations. Operating at 600 watts (X-ray tube), the MiniFlex 600 is twice as powerful as other benchtop models, enabling faster analysis and improved overall throughput. Running at 300 watts (X-ray tube), the new MiniFlex 300 does not require an external heat exchanger. Each model is engineered to maximize flexibility in a benchtop package. Read more...
