Simplified analysis of VOCs in paints and coatings

Eden Prairie, MN, May 23, 2019ASTM D6886, the “Standard Test Method for Determination of the Weight Percent Individual Volatile Organic Compounds in Waterborne Air-Dry Coatings by Gas Chromatography” has been revised to include the Polyarc system as an option. This revision simplifies the analysis workflow by eliminating the need to run standards to determine experimental RRFs. Furthermore, it increases the safety of the scientists and decreases the environmental impact of analysis by reducing chemical storage and waste. Initial ILS results for this revision showed similar repeatability and reproducibility to the original full-calibration method.

The Polyarc system is a breakthrough innovation that combines catalysis with chemical analysis to revolutionize 60-year-old GC/FID technology. The Polyarc converts all organic molecules to methane after chromatographic separation for a truly uniform FID response. Because of this conversion to methane, calibration of individual VOCs is not required; instead, single compound calibration yields highly accurate quantification of hundreds of compounds.

The Polyarc system is a useful tool for the analysis of paints and coatings because of the complexity associated with these samples. “This revision allows users to drastically streamline their analyses, and we’ve received great feedback from the users of the method about how the Polyarc will improve their lab operations,” said Tommy Saunders, Technical Contact for the method revision. “We’re very excited to be enhancing this method and to be a part of the ASTM process.”

The benefits of compound independent calibration with the Polyarc have also improved analysis workflow in a number of other industries, including chemicals, oil & gas, flavors & fragrance, and extractables & leachables. Overall, the Polyarc provides more accurate data by normalizing the FID response while also reducing the complexity associated with calibration. Visit our website for more applications.
