You may have already read an article or watched a report on the negative effects of Chinese drywall. These new reports show that defective drywall creates a variety of issues, including corrision of metals within the walls and possible health risks.
One method of determining if drywall is defective (problematic) or acceptable is to test for levels of Strontium (Sr); as defective drywall has 2-3 times the levels of Sr present. A recent study (lead by the CPSC) has proven that x-ray fluorescence is an effective method of determining Sr content.
One article (click here for full article) about the defective drywall problems and research into them notes that an outside laboratory “…found that by using handheld x-ray fluorescence (XRF)…they were able to detect markers that could identify Chinese-made drywall at a sheet-by-sheet level.” Those ‘markers’ are detecting Sr in parts-per-million (ppm).
Quickshot XRF is looking into this new application and how our technology can be beneficial in testing drywall. We will be offering new software packages and rental options to meet the testing need, so check www.quickshotxrf.com often for details or contact QSX Instruments to discuss.
