Top reasons why dental acid testing is Ineffective
Acid testing is a common way to distinguish how much gold is present in a simple jewelry alloy. This method is inappropriate for dental alloys because the composition is more complicated. For example, Platinum and Chrome will react to an acid test in the same way. They both will have a neutral reaction. Platinum is a valuable precious metal, and chromium cobalt is an inexpensive base metal. ...

Analytical Methodology for the Characterization of Steels and Iron Alloys by Atomic Absorption Analysis
The analysis of irons and steels has always been a very important job in the industrial and commercial environment. The grading of steels and iron alloys is critical to characterizing their respective strengths to corrosion and stress. There are also many protocols for the several hundred types of steels available. Fe is always the primary component, with elements such as Ni and Cr as ...

Sample preparation is the key to quality analysis with a laser analyser
Sample preparation is the most important step of any chemical analysis. To get the best results with any elemental alloy analyser regardless of the technology, the sample must be clean before taking a measurement. Otherwise the results are always compromised at least to some extent. The effect of dirty surfaces will vary and some technologies are more forgiving to sample surface conditions than ...

What is Laser Induced Breakdown Spectroscopy (LIBS)?
Laser Induced Breakdown Spectroscopy or LIBS is an analytical technique that's been used in laboratories for many years. Most handheld LIBS analysers are used for fast sorting of alloys in scrap yards, and alloy identification and analysis in various applications within the metals industry. Watch video here. How does LIBS work? During LIBS analysis, a focused pulsed laser hits the sample ...

Why detection limits matter in metals quality control
The new Hitachi OE750 spark spectrometer can measure the entire spectrum of elements in metals to low detection limits. For us at Hitachi High-Tech, this was the goal for the OE750 development team and why we ended up designing a completely new optical concept and using a different detector technology. Our view is that detection limits of below 10ppm or >1 ppm (depending on the application and ...

Next-generation OES analysis for total metals control
There’s never been a more demanding time for those in the metals industry. Foundries and steel plants are under increasing pressure to use scrap materials in the melt. Supply chains are getting more complex and perhaps less reliable. Legislation for trace elements is getting ever tougher. The result is that to be able to consistently produce a profitable, high quality product that meets all ...
