A drywall test should show a difference between a known domestic drywall and suspected tainted drywall. Quality control comparison involves the photo documentation of known domestic drywall and the suspected drywall.The high purity dispersion/suspension solvent must be proven to be free of contaminates. Two recoveries from drywall samples are compared to show consistence in the recovery. ![]() |

Tainted drywall is easy to distinguish with our drywall testing methods. Domestic drywall has certain characteristics that are consistent and easily distinguishable with the unaided eye when properly prepared. A drywall that is tainted will react and separate differently than domestic drywall when dissolved in high purity dispersion/suspension solvent. Color is a major indicator of both tainted and domestic drywall.

Chinese drywall is causing problems with everything from homeowner's health to damaged appliances. Drywall imported between 2004-2006 from certain areas in China can release sulfur-like odorous compounds. The extent of the indoor air quality issues related to this is still unclear. EPA is currently investigating the severity of the problem. However, it is well known that exposure to sulfur compounds can create irritation and breathing disorders. Call 561 577 7202 |
