This manual describes methods for testing chemical emissions from construction products, furniture and toys using gas chromatography-mass spectrometry (GC/MS) technology.
This document describes the use of Agilent Technologies' Thermal Desorption-Gas Chromatography/Mass Spectrometry (TD-GC/MS) systems for testing chemical emissions from construction products and consumer goods. It highlights the partnership between Agilent and Markes International to provide technology for meeting regulatory requirements regarding volatile organic compounds (VOCs) and semi-volatile organic chemicals (SVOCs).
The text outlines various testing methods, including chamber tests, emission test cells (FLEC), and micro-chambers, referencing standards such as ISO/EN 16000 and ASTM D6196. It details the specific capabilities of the Agilent 7890A GC and 5975C MSD systems, noting features like Electronic Pneumatic Control (EPC) and heated, monolithic quartz mass analyzers for high sensitivity and accuracy in emissions testing.
