BENEFITS OF USING A FID TO MEASURE THE MULTICOMPONENT GAS MIXTURES

Abstract

The development of the oil and gas complex is one of the priority areas of the Azerbaijan economy. Oil and gas are among the most competitive Azerbaijan goods and are in high and stable demand from global consumers. Therefore, increased attention is paid to product quality. One of the methods for quality control of petroleum products is gas chromatography. Today it is a widely used physical and chemical research method. The capabilities of a gas chromatography are mainly determined by the enormous separating power of the chromatographic columns and the characteristics of the detectors. If the chromatographic column is sometimes called the heart of the chromatograph, then the detector can be called the brain of the chromatograph [1,2]. Effective development of an analysis technique, its successful implementation, troubleshooting of a chromatograph, and metrological certification are impossible without the ability to make the right choice of a detector, operate it competently, and correctly interpret the detector signal. About 50 detectors have been proposed for gas chromatography, but only a few of them are used in practice. The most used are the flame ionization detector and the thermal conductivity detector. The article shows the advantage of using a flame ionization detector to measure important physical and chemical properties, such as density, caloric content, the ratio of the number of carbon atoms to the number of hydrogen atoms C/H. Keywords: Chromatography, gas-mixture, density, hydrocarbon, heat of combustion, calorific value, flame ionization detector, number of carbon atoms, sensitivity, quality.
