Three Common Problems with Old Handheld XRF Analyzers

The XRF service department of Eastern Applied Research has seen steady growth in the number of handheld x-ray fluorescence analyzers they service.  This is due to the fact that more and more handheld systems are in the field but also because older models are starting to have the typical ‘lifespan’ issues that require review and repair.

Our technical staff performs a wide variety of repair services on all handheld XRF analyzer brands and models but the three most common issues are very similar to the most common issues that occur with desktop analyzers – software related and the two major components.  Those three most common issues include:

Display Screen: The software interfaces of handheld analyzers are typically either integrated into the design of the system or an older model PDA.  Either way, issues with the screen (cracked, dead, etc) can be one of the most difficult repairs – if possible at all.  When it is an integrated design, it may not be possible to access the actual screen for review and when it is an older model PDA it is rarely possible to source out a replacement.  When issues occur with software interface, it is likely time to start considering replacement analyzer options.

X-ray Tube: Similar to desktop analyzers, the X-ray tube is a critical component and considered the heart of the system.  When problems occur with x-ray tubes, it can often lead to additional issues that result in more involved repairs than simply replacing this single component.  The Eastern Applied technical staff can confirm if problems are the result of a ‘dead’ x-ray tube and work with clients on confirming additional damages and what is required for repair.

Detector Tube: Often times detector tube issues can be identified right away…because they are the result of punctures to the tube window.  Fortunately, new ‘detector shields’ are limiting those issues but tubes still have a typical lifespan and will require replacement at some point.

While most handheld XRF performance issues can be repaired, at some point it is time to consider the repair vs replace debate.  With the recent advancements in handheld systems (particular the innovative XMet8000 series by Oxford Instruments) the benefits of investing budget into a new system will often times far outweigh the short-term cost savings to repair an older model.

XRF Standards DiscussionIf you are currently using an older handheld XRF system and notice any performance issues, please contact the Eastern Applied service center to discuss evaluation of the system…perhaps all it requires is some routine maintenance but our staff can assist either way.

Three Key Advantages of the PMI Master Smart, Mobile OES System

Optical emission spectroscopy (OES) is one of three metal testing technologies that Eastern Applied Research offers on behalf of Oxford Instruments.  The most popular of the OES systems is the PMI Master Smart.  Released in 2014, this newest OES system is the most portable unit on the market and provides a number of benefits that make it an industry leader in mobile OES.

Three of the benefits that make it a popular system for in-house incoming/outgoing inspection and with independent inspection companies are highlighted below…contact Eastern Applied Research with any questions or to coordinate an on-site demonstration of the equipment.

Grade Database
Unique to the Oxford Instruments OES line (both stationary and portable) is the pre-installed grade database that includes 4 million records, covering over 200,000 metal grades.  This database acts as an excellent cross reference tool for system users, providing the ability to search by chemical composition and mechanical properties, obtain heat transfer diagrams, and more.  Request Grade Database Information.

Efficient, Simple, and Flexible
Oxford Instruments developed the PMI Master Smart to be simple and efficient for any user, regardless of past experience. This includes an easy start-up process that makes it almost a ‘plug and play’ system along with operation that anybody can use after a short training session.  However, the mobility options that it offers set it apart from other portable OES systems. At a relatively light 33lbs, users can choose different transportation options like a back-pack or transport cart.  The flexibility of how it is moved, the variety of probes, and the chord length options give the system flexibility and access to most locations required for testing.

Analytical Performance
Optical emission spectroscopy is the technology of choice when proper grade separation requires quantification of light elements or the precise analysis of trace elements.  Common examples are quantification of nitrogen in duplex steels, trace analysis in stainless grades, and quantification of Carbon to properly separate 304 and 304L grades.  Examples of this precision are available from Eastern Applied Research and we can coordinate on-site demonstrations so that your organization can see the benefits that Oxford Instruments PMI Master Smart will provide in achieving your metal testing requirements.

If portable OES can benefit your material verification processes,
then the PMI Master Smart should be considered.
