PRODUCT FOCUS: Master GC Turn-key Analysers for Total Petrochemical Solutions
The determination of volatile and semi-volatile components in petrochemicals is of utmost importance to fulfill research, quality control, and process monitoring purposes. With this in mind, DANI offers complete solutions, including instrumentation, applications, supplies, and services, providing specialised turn-key analysers to meet the most challenging analytical demands. The flexibility and upgradeability featured by the Master GC Fast Gas Chromatograph (Figure 1) easily support an array of custom configurations for special applications.
The Master GC can be equipped with up to three injectors and three detectors simultaneously and allows the use of auxiliary ovens, gas and liquid valves, methaniser, cryogenic cooling device, making the Master GC the most suitable unit for the development of complex analytical systems for the oil, gas refining, and petrochemical segments.
DANI offers a wide range of turn-key analysers covering, among others, natural gas, liquefied petroleum, oxygenates in gasoline, and biodiesel analyses, meeting the specifications given in international regulations. All systems are controlled by the ClarityTM
Chromatography Station software, from data acquisition to processing.

Natural Gas Analysis (NGA)
As it is well-known, the commercial value of natural gas is based on its energy content; hence, composition analysis is strictly required to establish the heating value and BTU content. In view of the cost-driven natural gas marketplace, DANI offers the Master GC Turn-key Analyser which provides an innovative three-channel analysis to fulfill the demand of strict quality control routines.
The three-channel system (refer to Figure 2), based on micropacked columns - PLOT Q and Molsieve 5A,
uses a µTCD: channel 1 with helium as carrier gas for the detection of permanent gases and channel 2 with nitrogen to enable the detection of helium and hydrogen. On the other hand, hydrocarbons from C1 to
