XRF Chinese Drywall Testing
Feds: Homes with Chinese drywall must be gutted
Using an XRF to Detect (Sr)Strontium and (S) Sulfur in Chinese Drywall
In "Soil Mode" our XRF units can detect Strontium (Sr) and with the Light Element Analysis Package, they can do Sulfur (S) in the higher range. Chinese drywall is evident if the Sr is 1200ppm or more and the S is 2% or greater.
*Only units with the LEAP package can do Sulfur.
*Only units with the LEAP package can do Sulfur.
QUICKLY IDENTIFY DEFECTIVE CHINESE DRYWALL ANYWHERE Quickly and non-destructively screen for elevated levels of Strontium (Sr) in drywall Defective Chinese Drywall
Safety issues and property loss from imported Chinese drywall have been reported extensively. In November 2009, an inter-agency task force including a CPSC contractor, who used the Innov-X Systems Alpha Handheld XRF, released a report which includes methods to test homes for defective drywall. The presence of Strontium (Sr) at levels over 1,200 ppm has been found by numerous studies to be an effective indicator of Chinese drywall.
Testing companies and contractors have been using Innov-X Handheld XRF to screen quickly and non-destructively for elevated levels of Strontium (Sr), as well as Sulfur (S), in homes with suspect drywall. Homes throughout the southeastern US were hit particularly hard by this devastating problem.
Innov-X Systems and its Environmental Testing Partners will continue to help work towards a standard federal testing protocol. Current findings regarding the accuracy and precision of Handheld XRF as part of a draft protocol can be found in circulating publications. Links to some of these, including the CPSC Information Center, are found in our EXTRA section.
Innov-X Handheld XRF for Strontium (Sr) Screening
Innov-X Handheld XRF are used to test intact drywall quickly and easily without moving or destroying it. Several testing firms have found that elevated levels of Strontium (Sr) in excess of 1,200 ppm, and Sulfur (S) in excess of 2%, are indicative of Chinese drywall. Within seconds, Innov-X Handheld XRF can test for up to 25 elements, in the same test, providing additional information should it be required as the protocols evolve.
