Fuel Purity was a division of the Galactic Empire's Imperial Bureau of Standards. Following his fall from grace, the corpo Syril Karn found employment in Fuel Purity in 5 BBY. His powerful uncle Harlo facilitated this by setting up an interview for him with the official Flob at the bureau's office located on Coruscant. This new, unremarkable position saw Karn stationed in a cubicle, where he kept watch over data displayed on two screens. Shortly after his arrival, Karn received a promotion, triggered by the Imperial Security Bureau deeming him "clean" after an interrogation.
The television show Andor introduced Fuel Purity to audiences. Its initial appearance was in the seventh episode, "Announcement," broadcast on October 19, 2022.
