Purpose.

This test procedure is used for the quantitative determination of aldehyde and ketone emissions in vehicle interior cabin air utilizing a coated solid adsorbent followed by High Performance Liquid Chromatography (HPLC) with ultraviolet (UV) detection.

Foreword.

The determination of aldehydes and ketones in vehicle cabin air is essential to meet customer requirements and regulatory requirements in some global automotive markets. Concentrations are in the parts per million (ppm) range, which warrants accurate analytical measurements. This test procedure is based on a test method EPA TO-11A, published by the US Environmental Protection Agency in 1997. It has been updated to reflect new technology in air sampling and analytical instrumentation.

Applicability.

This test procedure can be used for all air samples for the determination of aldehyde and ketone emissions including cabin air inside vehicles in a stationary or dynamic mode. The results will provide complementary information to interpret findings in GMW3205 and GMW3059.
