Automotive fogging analyses by xenon UV exposure

摘要

Processes and apparatuses are provided for the liberation of one or more volatile organic compounds from a test sample. The processes include exposing a sample to light of a wavelength less than 400 nm, subjecting the sample to heat, and collecting one or more volatile organic compounds produced from the sample. The volatile organic compounds are detected by any of various methods, and are optionally identified by methods such as FTIR. The processes and apparatus provide for improved detection of relevant volatile organic compounds that are otherwise undetectable by traditional processes.

主权项

1. A process of detecting a volatile organic compound produced from a sample comprising:
placing a first sample and a second sample is a test chamber, said second sample placed entirely behind a support relative to the direction of a light source, said support transmitting less than 1% of light emitted from said light source; exposing for a first time said first sample to light from said light source, said light having a wavelength less than 400 nanometers, said exposing within said test chamber; subjecting said first sample and said second sample to a temperature; and detecting the presence or absence of one or more reaction products produced from a reaction of one or more volatiles from said first sample and one or more volatiles from said second sample, said reaction product produced from the step of exposing and the step of subjecting.
