In our first post about headspace gas chromatography (GC) analysis, we addressed the basics of the volatile components testing process. Static and dynamic headspace/GC analyses are surging in popularity driven by their ability to accurately determine blood alcohol levels and residual solvents in pharmaceutical production. As a result of their effectiveness, organizations in other industries such as cosmetics and food are using it to determine the presence and levels of volatile species in their liquid and solid samples. In this post, we will focus on how to get the best performance when implementing headspace/GC and the key issues to consider when preparing samples.

Part of developing new and relevant applications is staying on top of current events, which can mean reading through a lot of news articles. The one topic we run into most often, especially recently here in Ohio, is hydraulic fracturing. Recently, the governor of Ohio announced increased fees for dumping wastewaters associated with hydraulic fracturing from out of state sources. All implications are that these drilling activities will have a national as well as global impact, as evident by this map of the shale gas plays in North America.
