A Sample Preparation Technique Comparison for Dissolved Gas Analysis

Splash of oil.

The American Society for Testing and Materials (ASTM) Method D8028 is a method to determine dissolved gases in water. The method describes calibration and sampling techniques. One of the recommendations is to ensure the sample is sealed in order to safeguard the integrity of the sample. This recommendation is taken from United States Environmental Protection Agency (USEPA) Method 5030C used for the sampling of volatile organic compounds in water. Many environmental labs currently open their dissolved gas samples in order to place them in a headspace vial for sampling and analysis. This application will compare the efficacy of ensuring the sample is sealed versus opening the sample and pouring it into the sample vial for analysis.

Our Impact

EST Analytical has been helping labs achieve their analytical goals for over 30 years. Our vision is to engineer reliable laboratory instruments that enable partners to make the world a better place.

To help labs excel we offer Application Notes across our entire product line. They are a resource that explains the technology, performance, and abilities of our products as used against certain methodologies and or applications.

Whether your needs center around a USEPA method, an ASTM Standard, or a sample matrix-based outcome EST has you covered. If you don’t see the technical direction you need, simply contact us. We also offer sample analysis in our onsite Applications Lab.
