摘要

Increased regulatory visibility as well as process and product odor concerns have highlighted the need to accuratelyrnquantify the total volatile organic compound (TVOC) content in low TVOC samples such as paper coatings andrncoating components or high odor samples such as certain dyestuffs. EPA Method 24 has been the historical methodrnof choice but it is totally inadequate when TVOC levels drop below approximately 2%. EPA and Europeanrnregulatory agencies are aware of this deficiency and are working to develop alternative measurement methods. Thernalternative methods offer greater sensitivity than Method 24 because they measure the TVOCs directly. This paperrndescribes the measurement of TVOC content of select paper coatings, coating additives, and dyestuffs using EPArnMethod 24 and two proposed alternative test methods. The alternative measurement methods provided a significantrnimprovement over Method 24 in low TVOC samples. However, these proposed methods have serious deficienciesrnthat will need to be addressed before they can achieve widespread acceptance. Given the known deficiencies ofrnEPA Method 24, it is probable that some type of direct TVOC measurement technique similar to these alternativernmethods will supplant Method 24 as the standard test method for measuring TVOC content in low TVOC samples.
