Testing Chinese Drywall
I don’t have any of the signs of Chinese drywall, why should I get a test?
What do you use to test for problematic drywall?
Tainted drywall testing involves analyzing samples for known markers that are indicative of defective drywall. Several less expensive alternatives are being marketed, but FTIR and XRF look to be the future of accurate Chinese drywall testing.
Unequivocally, FTIR and XRF testing have been proven by the Consumer Products Safety Commission to be the most reliable Chinese drywall tests. These tests analyze drywall samples for carbonate sulfide and strontium respectively. Each of these tests provides nearly perfect accuracy. Defective drywall testing that utilizes both technologies in tandem overcomes any sampling contamination. Drywall compound, or mud, can show up in FTIR analysis as a false positive. That compound, however, does not affect XRF drywall testing.
Why aren’t all inspectors offering Chinese drywall testing that includes FTIR and XRF?
What makes Certified Chinese Drywall Testing different?
What does FTIR Chinese drywall testing involve?
FTIR, or Fourier Transformed Infrared Spectroscopy, relies on the measurement of infrared light that either passes through or is reflected by a sample. The resulting spectrum is compared against a library of known molecular fingerprints. No two compounds will produce the same results under FTIR analysis, creating a powerful tool for identifying unknown compounds at a molecular level.As it relates to drywall testing, FTIR is used to identify carbonate sulfide, a marker that the CPSC has identified as unique to Chinese drywall.
FTIR has been central to laboratory analysis for nearly seventy years. This technology is well establish and is respected and accepted within a court room setting. The fact that this technology is so credible and well established further reinforces its use for problematic drywall testing.
What does XRF drywall testing involve?
Who determined that these technologies are reliable for drywall testing?
–Draft Final Report CPSC Drywall and Indoor Environmental Quality Assessment. November 18, 2009. Pg. 104 of 128.
“Results from this study indicate that the concentrations of Strontium measured by XRF and carbonate ion (carbonate) using FTIR, determined that drywall can be used in combination to reliably identify suspect drywall.”

How is drywall collected for this analysis as part of drywall testing?
Comprehensive tainted drywall tests involve sampling and testing drywall throughout the home. In an effort to minimize the invasive nature of Chinese drywall testing, Certified Chinese Drywall Testing utilizes a specialized 1/4″ core sampling device. A third technology is utilized to guarantee that only one sample is taken per sheet of drywall. With this device, a drywall test is only minimally invasive while guaranteeing a comprehensive Chinese drywall test.Because this is the most comprehensive Chinese drywall test available, Certified Chinese Drywall Testing is the only company to offer fully insurable results! Other companies have Errors and Omissions (E&O) Insurance that covers Chinese drywall testing. These same inspectors then over to sample just a few areas of the home. The insurance only guarantees that the specific areas sampled are not defective drywall. These tests start at $2,500 and offer very little in the way of a true guarantee.
