Tips On Choosing An XRF Energy Analyzer

The first step in knowing what kind of energy analyzer to purchase is to figure out exactly what materials will be analyzed. There will be different grades or alloys to consider. Will the grade need to be matched or is it a case of the batch and heat chemistry needing to be validated?

When speaking of an XRF energy analyzer, there are really only two types of detectors. These two types will be SDD & PIN. The PIN types have been around much longer but they are also far less sensitive than their SDD cousins. Essentially, to figure out which type you will need you should ask three questions. 

First, will you be analyzing light elements? These elements are defined as aluminum, silicon, magnesium, and phosphorus, along with a few others. If the goal is to determine the concentration of these elements than an SDD analyzer will be needed. 

Second, you must ask yourself if speed is a contributing factor to the purchase decision. An SDD energy analyzer will be able to identify any metal alloy within 2 seconds. A PIN version will take approximately 8 seconds. While 6 seconds does not seem like a lengthy amount of time on the surface, when this is multiplied over a huge batch of samples to be processed, it can lead to huge cost savings. In terms of energy analysis, it is always all about the bottom line of the business before anything else. 

Third, consider the extras that accompany the energy analyzer. Will, you need a camera located somewhere on the analyzer and will this camera need to be able to connect wirelessly to be able to transmit data. All of these questions will help to make an effective decision when it comes to purchases.
