As international quality standards become increasingly demanding, you need to be confident in your QC analysis results – whether you are using an XRF, LIBS or OES analyzer. Without an accurate error margin, you simply cannot be sure that your parts meet specifications.
Whichever analysis method you use, every measurement made has an error margin associated with it. Usually, we try to reduce the error margin by using the best and most appropriate measurement system. For example, to measure a small component, we would use a micrometer and not a meter rule. Yet while the error margin can be reduced, it is never eliminated.
