In a previous article, gas chromatography was described as the most popular method for Dissolved Gas Analysis (DGA) conducted in laboratories. In this article, Marius Grisaru describes the established and prevalent DGA method for online and portable devices.
Over the last half-century, most DGA analyses were performed by electrochemical detection. Such methods are reliable, accurate, and provide simple, low-cost, and fast responses to most malfunctions. Despite these advantages, electromechanical detection has fallen out of favor over the last two decades, giving way to new gas measurement methods.
