Here’s a great story from the front lines of LIBS testing, courtesy of our Applications Manager in Asia Pacific. Only the names have been redacted, to protect the innocent….
We were in Japan and stopped in to visit an intrigued customer. (We did not receive permission to release any names, we were lucky to get these pictures.) They produce oiling systems for large machines in petrochemical, power generation and cement plants and currently own a Spark OES and XRF for their testing needs.
We met with the customer and were given a box of samples. These samples were stainless steels in shapes that the Spark OES system they owned could not test, piping L and T joints. They also wanted to look at L grade welds. While most of samples were too small or too curved for their current Spark OES system to test, upon getting proper grinds on the samples, we were easily and accurately able to test them. This happened throughout Japan. The first test we took with our LIBS of any L grade produced a gasp of disbelief, a verbal “whoa” upon seeing both the initial results and the subsequent repeatability of those same results.
The customers were amazed that a handheld unit could do this type of testing. They were amazed that it handled oddly shaped samples with such ease without the need of special nozzles or recalibration. The small spot size of the unit allows customers to further expand their current testing programs. The ability to test narrow weld spots (< 1cm) will ensure the utmost quality. The ability to use the camera to specifically aim at the area of interest is a huge advantage. These customers left the demo with a newfound respect for LIBS and its ability to fill the gaps in their current testing program.
Important take-aways here: Our ability to excel on parts that Spark OES or XRF cannot easily test really amazed both the distributor and the customer. In particular, testing small welds and unique shapes really drew interest on the incoming QC and PMI of parts. So, having a LIBS system really complements current portable testing programs by adding exceptional advantages that customers haven’t been able to do before. These customers feel that by adding LIBS to their testing programs, they are gaining an advantage of true quality assurance.
