A More Cost-Effective Carrier Gas for Volatile Organic Compound Analysis

The price of helium continues to rise and its availability is inconsistent. As a result, many laboratories are searching for more cost-effective carrier gas options. Innovative gas chromatography systems are capable of significantly reducing helium usage. This informative webcast will discuss a purge and trap system capable of using two different gases for operation. While helium is used as the carrier gas, maintaining existing performance, a less expensive gas, such as nitrogen, is used for the injector split and purge and trap purge phases. The presentation will include data from studies using the most common U.S. Environmental Protection Agency (EPA) volatile organic compound (VOC) methodologies.

Topics include:

• Why is helium conservation important?
• General instrument overview
• Alternative gases
• Comparative data on VOC analysis
• Calibration and method detection limits
