New Chinese Drywall Screen Tests Available for as Little as $61


EMSL Analytical offers six testing solutions for Chinese drywall problems.

Westmont, NJ

Since early in 2009 there have been numerous media reports about imported Chinese drywall causing unpleasant odors, damage to building materials and making people sick across the country from poor indoor air quality (IAQ).

EMSL Analytical, one of the nation’s premier environmental and materials testing laboratories has been inundated with calls from builders, environmental consultants and the general public about testing samples of suspicious drywall. In response EMSL Analytical has developed a series of tests specifically for Chinese drywall samples, which include:

Test 1. Analysis of drywall samples for the presence of total strontium (Sr) by ICP. This inexpensive test priced at $61 is used as a screening procedure to indicate if strontium sulfide is presumptively present in the sample.

Test 2. Analysis of drywall samples for the presence of impurities [iron/Fe2S and strontium/SrS] by X-ray Fluorescence-XRF, X-ray diffraction-XRD and light microscopy.

Test 3. Analysis for the presence of Volatile Organic Compounds (VOCs - especially for organic sulfides). This test indicates if drywall samples emit sulfur-based gases capable of producing corrosions.

Test 4. Analysis of drywall samples for elemental sulfur/BNA analysis. This test indicates if drywall samples emit sulfur-based gases capable of producing corrosion.

Test 5. Analysis of copper wires or surfaces by SEM/EDX. This test indicates if the corrosion of copper surfaces is associated with the components of the drywall.

Test 6. An accelerated corrosion test that provides a qualitative analysis of the drywall for its propensity to corrode copper in environmental chamber exposure.

“Chinese drywall has caused enormous problems in thousands of homes that used the materials that were imported from 2005 through 2007,” reported Joe Frasca, Senior Vice President at EMSL Analytical. “EMSL’s Materials Testing Division has been on the forefront of offering testing solutions to help identify and solve this ongoing problem and we are pleased to announce these six affordable testing solutions,” he continued.
