RoHS Test Equipment: Benchtop or Handheld XRF?

Quickshot XRF recently released the QSX-82D, a desktop x-ray fluorescence analyzer that was developed specifically for RoHS testing needs.  With the release of this system, organizations have both a desktop and a handheld system from Quickshot XRF to consider when looking to add in-house RoHS testing capabilities.  Both systems present different benefits that will meet various end-users interests and this blog touches on a few benefits of each.

Concerns over the difference in accuracy and repeatability of the two systems are topics that most organizations want to discuss.  This is, essentially, a non-factor as both technologies offer the ability to read at PPM levels well below RoHS requirements.  Although, the increased sensitivity the desktop system provides allows it to outperform the handheld when testing metal samples for hazardous substances.

We ran some tests on a sample piece using both systems and a summary of those tests follow:

XRF Testing Results of RoHS ComplianceAverage Reading (in PPM)
note that the largest difference between average results was only 4.28 PPM; in Bromine

Standard Deviation of XRF ResultsStandard Deviation
fairly tight repeatability from each analyzer

Handheld XRF (QSX-HH)
This very popular option from QSX Instruments Inc can provide a good screening device when companies require portability.  Many organizations like that it is available for rent; which provides the option to credit the entire rental fee to the purchase price – making it a popular way to try XRF Technology for an extended period of time before making the full investment.

Top Benefits of Handheld XRF
     -  Portable Testing; good for incoming inspection interests
     -  No Limit to Sample Size; a benefit for testing larger boards that can’t be destroyed 
     -  Cost; only QSX Instruments offers a handheld system at thsi price for RoHS testing 

Desktop XRF (QSX-82D)
RoHS-Test-EquipmentThis system was developed for organizations that have a need to test smaller components for RoHS compliance.  The camera system allows for focus on a specific area and the image is included in reports.  Many users of desktop systems appreciate that the software operates on a computer (not a PDA like handhelds) making it easier to navigate and the reporting capabilities are much more impressive.

Top Benefits of Desktop XRF:
     -  Software; easier to navigate than handheld and better report functions
     -  Color Camera System; insures proper sample alignment
     -  Multiple Filters and Collimators; increased sensitivity and detection limits

At the end of the day, QSX Instruments can not offer a standard answer for what system is the better option.  The decision must be based on the individual organizations testing needs and situation, but both systems can provide accurate information with different benefits.  Feel free to contact a QSX Instruments associate to discuss your testing interests, concerns and the benefits of each analyzer style.
