  • A New Paradigm In Aeration Technology
    A New Paradigm In Aeration Technology

    The DO2E organization sprang from one individual’s attempt to solve an aeration problem in a fish hatchery and realizing that his device to do so had many other applications as well. This device broke up algal blooms as well as aerating, and it was only a short step to modify it into breaking up FOG (fats, oils, and grease) deposits in grease traps and lift stations. This device was patented, thus DO2E was born.

Purge and Trap Background 
When using a concentrator system, it is not essential to understand how it works. However, a good grasp of the fundamentals helps you prevent problems and assists you when you are faced with tasks such as method development and troubleshooting. This section is not intended to be a full theoretical evaluation of purge and trap gas chromatography. The main purpose is to help you develop an understanding of how and why compounds are concentrated.
