Spectroscopy vs. Spectrometry – What’s the Difference in OES?
Jul 24, 2017 | Metal Analysis Testing Equipment
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,...
HOW TO DETERMINE CARBON CONTENT IN STEEL
Jun 22, 2017 | Metal Analysis Testing
Carbon is one of the most abundant elements available in nature. It is readily available in the earth's crust and the atmosphere. Carbon is often found as a constituent element in many compounds and substances. Because of its advantageous attributes, it is used in the...
Why Renting OES Equipment Can Be Beneficial
Jun 20, 2017 | Metal Analysis Testing Equipment
Need PMI testing and want to do it in house but don’t want to spend the money to purchase an instrument? The decision to invest in OES instruments or to rent is not a decision made quickly. Besides identifying exactly what type of testing you require and match that to...
Why OBLF Spectrometers?
Apr 11, 2017 | Metal Analysis Testing Equipment
Spectrometers are an investment that most companies want to get right the first time, so it is not something you are likely to reach a decision on in a single sitting.It will take time and research, as well as the comparison of a number of different models and...
Common Metal Identification Methods
Dec 1, 2016 | Metal Analysis Testing
The ability to identify metal is a valuable skill for many operations such as welding, machining, cutting, and fabricating. Metal workers use various methods, from traditional to modern ones, to identify the scraps and sheets of metals that come into the shop. In...
What is Carbon Equivalent?
Jul 11, 2016 | Metal Analysis Testing Equipment
Metal alloys are composed of a variety of elements, each having its impact on the properties and performance of the alloy. Carbon equivalent (CE) is an important factor to consider when selecting an alloy for a specific application. To discuss Carbon Equivalency, we...
Setting PMI Test Standards
May 20, 2016 | Metal Analysis Testing
What are standard operating procedures? Standard operating procedures are detailed instructions on how to carry out a particular job. For positive material identification, PMI testing, these instructions will describe exactly how the sample is to be prepared, what...
How Does PMI Work?
Apr 13, 2016 | Metal Analysis Testing
WHAT IS POSITIVE MATERIAL IDENTIFICATION? Positive Material Identification, or PMI, is an analysis technique used to verify the material chemistry of metal alloys. The surface of the alloy is excited through electrical stimulation and the resulting waves of the light...
Field PMI for C,P & S is a Challenge
Jun 8, 2015 | Metal Analysis Testing, Metal Analysis Testing Equipment
Laboratory OES can easily detect Carbon, Phosphorus and Sulfur with-in metal alloys. Take the Lab OES technology and put it in a mobile package and the results will vary. What creates this variance? Sensitivity to Vibration Laboratory and Mobile OES instruments use an...
Carbon Steel Testing
Jun 2, 2015 | Metal Analysis Testing
Carbon steel is produced in multiple grades and alloying chemistries. Separating carbon steel grades such as 1018, A36, 1144, A366/1008, 1020 and 8620 can be extremely difficult with a handheld XRF unit because of the unreported carbon value and the lack of low limits...
