The Agilent 6890 was introduced in 1996. When introduced, the 6890 was the first Electronic Pneumatic Control (EPC) system. The EPC system allowed for the adjustment of the internal systemic conditions based on the ambient temperature and barometric conditions of its surroundings. This enabled better retention times and peak area/height reproducibilities. This technological development allowed the 6890 to grow into the most popular GC system for laboratories around the world.
