Smart Microchip-based Gas Chromatographs
Natural gas is one of the most important energy resources1. However, its chemical composition can fluctuate considerably, depending on where it is found. Added to this, the various gas qualities are mixed together due to the networked pipeline system of main and sub branches, receiving and transfer stations and gas storage facilities. This means that the natural gas must be tested qualitatively and quantitatively at strategic points to establish its volume and its quality parameters such as its calorific value (CV or Btu), hydrocarbon dew point and hydrogen sulfide content.
