What is a Rotrode Emission Spectrometer [RES]?
RES stands for Rotrode Emission Spectrometer, which is a type of tool that is used to determine metals present in oil samples. It is a specific designation based on the size of the particles that the spectrometer can detect, typically the detection limits...
Elemental Analysis Using Optical Emission Spectroscopy
Elemental analysis has been around since the early 19th century when Louis Jacques Thenard and Joseph Louis Gay-Lussac conducted research on electrochemical analysis. It has evolved steadily over time, but has dramatically progressed over the last two...
Spectrometer Units: What Does a Spectrometer Measure?
Spectrometry and spectroscopy are related but they are not the same thing. Spectrometry is the application of spectroscopy; spectrometry creates quantifiable results for later assessment. Once you understand the basics of spectrometers, you will need to...
X-Ray Diffraction Testing
X-rays are commonly associated with the medical profession, but their application actually has numerous uses in many other areas. X-ray diffraction testing, commonly called XRD testing or XRD analysis, is a form of positive metal identification used to...
What is Hardness Testing
Hardness can contain a number of meanings. In the metals industry, it can be thought of as a materials resistance to permanent deformation. To a metallurgist, it means resistance to penetration. To engineers, it could be resistance to wear,...
Spectro Analytical Instrument Used for Metal Testing
Spectro has been in business for nearly forty years. They make analytical equipment to test metals. The company has worldwide operations although they have their headquarters in Germany. When looking for a Spectro analytic instrument for metal testing, it...
What is Positive Material Identification?
With so many different ways of analyzing metals that various companies use, it can be difficult to understand exactly how your product or item is going to be tested. One of the most important decisions you will make is whether to use a destructive or a non-destructive...
Destructive vs Non-destructive Metal Testing?
Although it has historically been the preferred method of testing method, destructive testing has also been largely the only way to gain accurate results. With the technological advances, non-destructive testing methods are proving to be accurate, efficient and...
Scrap Metal Recycling 101 – A Guide For Complete Beginners
You can’t turn anything you touch into gold, unless your name is King Midas. But believe it or not: You can help save the environment by turning junk into cash. Perhaps you’ve heard about scrap metal recycling many times before. Maybe you’ve read about it, too, but...
Spectroscopy vs. Spectrometry – What’s the Difference in OES?
Optical Emission Spectroscopy (OES) uses a lot of terms, and occasionally some of them are inaccurately used interchangeably. Though there are certain similarities, spectroscopy and spectrometry are not the same thing. To better understand the difference between them,...
